I think you might like "Data munging with Perl, DBI, SQLite" quite well for this then. But it is a different mental paradigm from the command line data filter. As a program it will attach to the database and then you can loop over the data there. That would give you the ability to do whatever you wish to the data. But as other people have mentioned as soon as you use a database the data is no longer in simple text files. The database itself is binary. You access the data through any of a number of programmatic interfaces. It is possible to load plain text data into the database. It is possible to dump the database out as plain text files. That may be sufficient for you. You could cause all of that to be a filter. Start with plain text. Load it. Process it. Dumpt it out as plain text at the end. The extent to which this is lossless depends upon whether you have established relationships between tables in the database or not. Since SQLite is a relational database. You could have a field in one table called item_id and have it refer to another record in another table. That is the typical type of relationship. That isn't easily communicated in the type of plain text files you have described so far so I assume you do not have any such relationships in your data. But you know your data so you can decide that for yourself if what you are doing fits doing it that way or not. Bob signature.asc Description: Digital signature

They have an easier task of identifying the file. They only need to
identify the file for the file types that they can play. They don't
need to identify every possible file type.

I have never seen the file utility built into any shell. The file
utility relies upon the magic file which contains a small descriptive
language programmed to identify files by content. I think that would
be too much to incorporate as a shell builtin. It just does not get
executed that often so not enough return on the investment.

That says that there isn't anything programmed into the magic file in
order for the file program to identify the file. If someone programs
in the identification then the file command could identify it. But
regardless of you showing that it does not handle qs files the file
utility does quite well with most file types.

Actually file can identify docx files.

foo.docx: Microsoft Word 2007+

Different players use different codec libraries. And in Debian things
are more confused because of the fork between ffmpeg and libav.
Debian chose the libav fork. In hindsight that was probably a bad
choice and I think we would be better off with ffmpeg instead.
In the end it means that every player is slightly different. It is
all related to the file encoding. Some work great and others don't
work so well. (shrug)

building .debs with "+b1" on the end
I want to re-build a package for personal use, and have a special version number for my custom build. Since I'm not planning on customizing the source or the debian control files, I think the ideal choice is to build a binary package with a suffix like "+b1" or "+local" on the end. An example of this sort of thing is the current wheezy package of "libcrypt-blowfish-perl" (https://packages.debian.org/wheezy/libcrypt-blowfish-perl) As near as I can tell, the 2.12-1+b2 .debs of this package was created after the 2.12-1 .debs, but from the same source code, and without creating an entry in the changelog. How would I do this? I've looked in various places, and I can't find any relevant documentation. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Over-provisioning is the reserved space that the vendor keeps to so that the physical layer of the storage device never actually becomes very full. The more the vendor does over-provisioning the less full the drive can get. Even if the logical layer appears full. The drive needs big blocks of free space in order to be able to operate since it will erase in large blocks. And of course that reduces the impact of not using trim. This is why I don't think an SSD would degrade in performance very much at all when the logical layer of the file system is very full. Bob signature.asc Description: Digital signature

Uhm, is text not a subset of binary (when talking about the contents of the files that implement a database)? Does SQLite encode text fields in some non-human-readable manner? Okay, thinking about it a bit, the lack of delimiters, and the puzzling nature of binary zero when trying to read it as text, might be what Nuno was referring to.

For some people seeking to keep data in text format, that might disqualify SQLite. Apparently not the OP?
what was broken with sysvinit? some thoughts on initialization "systems"
The first problem I notice with sysvinit is that it is not a (single) initialization system. Or, that may be the only problem, other than that it is a feature rather than a problem to those who understand the issues involved, whereas it is perceived as a problem by those who expect a system. Attempting to unpack that a little, I do remember a time when I was looking for some centralized way to control what was being started when, and being a little stressed out to discover I would have to learn sh for real if I wanted to play with what boots up when. And then I would have to read and understand the programs -- scripts -- being used to get everything started. And one of the distressing elements it all was the ad-hoc nature of the collection of init scripts. The only thing systematic about any of it was the loose framework of runlevels and the method of controlling boot order by tagging a script's filename with a priority number and then trusted the collating order. Which felt a lot like line numbers in basic programs, plus some extra chances for confusing oneself. It took me several years (and playing with MSWindows's Wrong Way To Get It Right) to see that ad-hoc nature of sysvinit was, indeed, a feature, not a bug. Sysvinit has been evolving, so that certain common features of services could be accessed through more central tools -- chkconfig and such. Also, the nomenclature has evolved quite a bit, so that, when you read the documentation for one set of daemons and pick up the documentation for another, you don't tend to be as lost at first. Likewise, the structure of the scripts. What I want to see, rather than the implementation of a system where a system doesn't belong, is more evolution of the sysvinit set of systems, more cooperation between the teams working on the various services/daemons, so that methods of communicating dependencies and status information can be made more regular. Systemd does seem to provide a forum for such communication, but I question the cost of the forum -- abandoning the ad-hoc, flexible nature of sysvinit for the confined, and confining vision of a small group of engineers whose (there's no way to avoid saying this) egos exceed both their experience and their vision. Sometimes, no, often in engineering fields, an inexperienced engineer has been able to clear the air of irrelevant arguments and provide a catalyst for real solutions when the experienced engineers have been blinded by their experiences. And the new solution solves things. I see some catalyzation of new approaches and such, but my present impression of systemd is that it is heading away from the solution, seeking the illusion of a solution found in Microsoft's stuff. However, I can hope that the experiment with systemd, after having run its course, might provide us with more tools to return (yet again) to a more organized and accessible sysvinit. The point of this ramble is what? I'm not sure. But, rather than rant about how stupid systemd is, perhaps we can get a working group or two set up to figure out how daemons and their packages should communicate their dependencies and status with each other? Then we could really solve the problem systemd is not solving right now, and either fix systemd or discard it as necessary.

Doubting the veracity of information you are given is one of the responsibilities you accept when you start thinking for yourself. Calling a peson's choice about how he spends his time "dubious grounds" is one of the principle tools of tyranny. Even parents trying to help children understand they are the root cause of their own problems should avoid using such arguments.

Re: Clone GPT partition table - with Lenny ?
Other than not being fully automated, what would be wrong with: - use dd to copy the first 10MiB of the old drive to the new, - use dd to skip all but the last 10MiB of the old drive and seek to the same spot on the new drive - use dd if=/dev/zero to zero the first MiB of each partition. That *should* guarantee that the partition structure is copied from the old drive to the new and that no partition contains RAID IDs. You have to think about what you're doing, but it should work and allow mdadm to equalize to the new drive. Also, unless I'm mistaken, neither hard drives nor hard drive controllers have used CHS in many years, mostly because CHS has not been constant across the platter(s) in about as many years. Far as I know, only partitioning tools gripe about CHS alignment. It's why I stopped using fdisk, sfdisk and other ancient partitioners. And I came close to scrapping parted because it can't do simple arithmetic; but using 'unit s' works well enough, provided I do all the begin/end computations outside of parted.

Those are helpful examples. I'd forgotten about perl's
autosplit mode (the -a in -lane) which splits the input
lines to @F. It makes sense that the -F option is the
same in perl as for awk.

B, thank you. dd leads to problems with RAID, though. I did try that first, and messed the system up further. I hadn't included that story in the original post, because I hadn't wanted to write something too long; but here it is. Debian Lenny uses Lilo to boot from a RAID1 and when you do a dd over sda -> sdb you do, indeed, get a bit for bit copy. But, you also get an exact replica of the disk ID, and Lilo complains about that (but does go on to boot). More seriously, mdadm seems to have a kind of 'dynamic' or 'live' repair/re-assembly capability. While I was dd-ing, mdadm tried to also do a re sync on each partition as it came into existence. (I was surprised by this.) The result was two programs writing to the same areas and mdadm evenually entered a somewhat strange state, and stated renaming the /dev/md[n] to something else - I now have a /dev/md126, even though mdadm.conf still has /dev/md2. But I've left it because the system does boot up, for now. So, the RAID1 isn't perfect yet, and won't be after the 2nd disc is added, but I see on the linux-raid list that someone else has reported this issue of md renaming so I hope to fix that, as well, afterwards. So I do just want to clone the GPT partition table, if I can, and let mdadm re sync the data in the partitions. DD does seem attractive, I agree, but leads to problems in this instance.

Just for the archives, the file extension is a poor indicator of the

Clone GPT partition table - with Lenny ?
List, good evening, We have a RAID1 server running Lenny, one of whose two 2TB discs comprising the RAID arrays has failed. The discs were partitioned into 8 partitions during the Debian Lenny installation, and separate RAID1 arrays were built on 7 of those partitions, again during Debian installation. The Debian installer employed a GPT partition table for these discs; it also chose the (precise) partition boundaries. The machine is no longer an active server on our network; its role has been taken by a new-build Wheezy box. The end goal is to restore the RAID1 arrays, then update the properly configured machine to Wheezy. So I need to partition the new disk, and I'd like it to be an exact clone of the existing RAID1 member, so that each partition starts on the same sector, etc. I can then repair the arrays using mdadm. As far as I can see, there is no command in fdisk or parted that will clone the partition table for me. I can create a partition table on the new disk, but I will need to have the exact partition start and end points, to be sure of exactly matching the existing disc. Is there, in Lenny, a command or tool for cloning a GPT? Alternatively, how could I find the exact partition start points on the working disk, and sizes, etc, to help me partition the new disk?

Microsoft Word woth the proprietary .docx extension, would also
probably show as data, but, I doubt that mplayer, or vlc, or totem,
would work with that .docx filetype.
The above output for the file command was previously posted in the

And, I have found that vlc (running on Debian 6), has a problem with
some of the files, in that the output for some of the files, as with
the output for mplayer, is choppy (if that is the correct term),
meaning that it will play a little bit, then stop, then play a little
bit more, a bit like the reproduction from the movie projectors from

But the problem comes when you have to delete/insert a new column into existing data. If you delete, say field_5 column, you have to change the index in awk scripts for all the subsequent fields. I thought a better approach might be to refer to the columns by their header names, so I thought a database might be appropriate. raju

The `rules` file seems to be the source of the problem. Change $(MAKE) DESTDIR=$$(pwd)/debian/hithere prefix=/usr install to $(MAKE) DESTDIR=$$(pwd)/debian/tmp prefix=/usr install and try again. If it is your own application you are compiling this way, I suggest you to configure the application's makefile to automatically create necessary file structures in order to be able to keep the `rules` file as simple (and as compatible...) as possible.

I think it's a matter of sucky documentation, which is rampant. First, the makers of software do a lousy job of documentation. Second, everyone with half an opinion puts yet another contradictory "fix" or "tip" on the Internet, and if they test their fix or tip at all, they test it in only one situation. And, if I had my way, it would be a felony to use a pronoun in documentation. Redundancy is wonderful compared to confusion. And how bout those guys using a word or phrase that hasn't been defined in the documentation, and is known only to people already past the point of needing the documentation? Computers and Linux just keep getting more complicated, and documentation just keeps getting worse. I'm pretty sure that if we all had good documentation, we could modify our boxes to our hearts' content without undue mishaps. > > 4. Systemd is turning a lot of heads and postings.

New 64bit install. More problems.
1. /var/mail/usermail very large, containing hundreds of messages. Should only have 10-20. This file serves a dovecot imap server and messages have been read and deleted. What is going on here?

Re: Preseed and security packages during install
Well, the problem with netboot preseed is that it takes a mirror - and the official mirrors only have the latest on deb 7 and the latest on deb 6 unless I’m mistaken. So even if I try to use a netboot from 7.4 I will still get 7.5 through the mirror and the install will fail to find the discs. I just completed the install manually in this case through 7.4 ISO CD without issues, but it’s quite a hassle when you’re using to just pxe booting and getting it all served to you ;) I’m used to CentOS where you can choose exactly which version you’d like to install from the repo using a network install.

As long as your /tmp does not normally exceed your RAM size it might be a good idea. Still, it is not really SSD specific: It will of course save a few writes, but as long as /tmp is always smaller than your RAM, there are obviously not that many writes anyway. > Lastly, the partition alignment discussion on > http://tytso.livejournal.com/2009/02/20/ is from 2009 - is it relevant > today?

None of the modifications is "necessary". You can simply replace a HDD with a SSD without having to worry much. Still, a ramdisk for /tmp could be useful (also in HDD environments).

To do it for test purposes, you boot to the GRUB menu, highlight the menu entry you would normally boot from, and press 'e'. In the resulting list, the kernel command line is the one mentioning 'vmlinuz'. Add the parameter to the end of that line, and boot the rest of the way.

If/when you want to make this permanent, you'll need to fiddle with /etc/default/grub and/or /etc/grub.d/* (I suspect more likely the former), and run the 'update-grub' command afterwards. Or you could just install the systemd-sysv package, assuming that's available, which makes all the necessary changes automatically. - -- The Wanderer Secrecy is the beginning of tyranny.

Fools rush in where Angels fear to tread: systemd
I am a foolish user of Wheezy. I want to see for myself what will happen if I switch to systemd today. I find on wiki.debian.org/systemd a document with steps needed to install and test systemd, but I have trouble: After using apt-get to install the systemd package the next step is (verbatim): To test systemd before switching to it by default, you can add the following boot parameter to the kernel: init=/bin/systemd (end verbatim) How do I add this parameter to the kernel? I think I must open some file somewhere, probably in /etc and edit it with vim or emacs (hopefully my choise) and I should place this string correctly within that file: What file (full path) ? What position within the file? I think I might be able to guess the position, once I know the path to the file, and can read its pre-existing content, but I am not such a fool as to assume that the position will be obvious to a fool.

Preseed and security packages during install
Hi, I was recently bit by the bug listed here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746642 which resulted in my new SATA drives not being recognized during a Debian 7.5 install. Is there anyway to install 7.5 with my sata card without installing 7.4 from ISO first? I’m using PXE-boot with the netinstall iso and a preseed file. The security packages are added AFTER the detection/partitioning of disks so I’m unable to detect the drives. Any idea how to solve it? Is it even possible? I’ve tried modifying the netboot initrd and add firmware to it, but it seems that during netboot it actually downloads the latest stable.. Kind Regards, David

This is what the > systemd-shim project is intended to allow (but see below). So in other words, at least as far as the systemd project itself is concerned, you can't. (I'm assuming systemd-shim is not a product of the systemd project, since that project's developers seem entirely content with just the main implementation and it seems unlikely they would want to host two parallel implementations of the same interfaces in the same collection of projects.) Also, I wasn't talking about running logind without systemd "as PID 1", although of course that's a major consideration; I was talking about running logind with systemd possibly not even present on the system at all. I.e., completely independent components, which may simply be able to interact with and enhance one another. >> Can you run journald without systemd or logind? > > I don't know. The question seems somewhat moot to me, since I've seen > people who like systemd in principle but think journald is a > terrible idea, but I don't think I've seen someone who likes journald > but thinks systemd is a terrible idea. The question isn't about what someone necessarily wants to do, but about whether systemd et al. are monolithic or (independently) modular. systemd's advocates claim that it is highly modular, and (to quote from this very thread) "anything but monolithic". If the various components of systemd are independently modular, than each one can run - possibly, though it would be to be hoped not, with degraded functionality - without any of the others present. If they cannot do so, then they are not independently modular - and, by implication, are at least partially monolithic. >> If you can, then why is it that libpam package dependencies which >> appear (if I've understood the discussion correctly) to be about >> functionality now provided by logind are pulling in systemd *as the >> active init system* automatically? > > There appear to be two facets to this: > > First, the dependency on systemd's interfaces is expressed as a > Depends entry of the form "systemd-sysv | systemd-shim", so as I > understand it "install systemd-sysv" ends up being the default method > of resolving the dependency because it's the first entry in the > alternation. > > Second, logind >= 205 has a further interface dependency on systemd > (logind <= 204 sets up cgroups by itself; logind >= 205 relies on > systemd >= 205 to do it) which the current version of systemd-shim > does not yet fulfill: > > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=752939 Which seems to indicate that far from being non-monolithic, systemd et al. are moving towards being *more* so, by making something that previously was capable of running independently no longer capable of doing so. (As far as I can tell, logind itself exists only as the binary 'systemd-logind', which is packaged as part of the systemd package rather than in its own logind or systemd-logind package. The same sort of thing appears to be true of journald, hostnamed, localed, shutdownd, and timedated, the latter four of which I hadn't even heard of. That's another aspect of the "can't get one without the others" factor which is what leads people to describe systemd as monolithic.) This type of change gets made in the name of tighter integration and increased efficiency, and it probably does provide that. But it does so at the expense of decreased modularity and interchangeability, and makes the system as a whole more monolithic - with all the negatives that implies. (I have further discussion and possibly argument on the topic of init-system-related dependencies, which does relate to the modularity vs. monolithism argument, but I've deleted it here as being a distraction from that main topic.) - -- The Wanderer Secrecy is the beginning of tyranny.

SSD optimization on Debian (2014)
Hi all, I wanted to upgrade my system to amd64 and used that opportunity to install 2 240GB (1GB = 1000MB etc. unfortunately) SSDs on my rig. The partition map is below: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:00 223.6G 0 disk ├─sda1 8:10 186M 0 part /boot ├─sda2 8:20 1K 0 part └─sda5 8:50 223.4G 0 part ├─gp01-root (dm-0) 254:00 1.9G 0 lvm / ├─gp01-swap (dm-1) 254:10 1.9G 0 lvm [SWAP] ├─gp01-usr (dm-10) 254:10 0 23.9G 0 lvm /usr ├─gp01-tmp (dm-11) 254:11 0 4.8G 0 lvm /tmp ├─gp01-var (dm-12) 254:12 0 4.8G 0 lvm /var └─gp01-home (dm-13) 254:13 0 186.2G 0 lvm /home sdb 8:32 0 223.6G 0 disk └─sdb1 8:33 0 223.6G 0 part └─gp02-virtual (dm-2) 254:20 143.1G 0 lvm /virtual so there are two LVM volume groups with the first one on sda hosting the OS and second on sdb using 1 partition for my VMs. I have done the following for optimization (ref: https://wiki.debian.org/SSDOptimization?action=show&redirect=SSDoptimization): 1) Kernel: Linux localhost 3.14-1-amd64 #1 SMP Debian 3.14.9-1 (2014-06-30) x86_64 GNU/Linux 2) Updated the firmware for the Intel 530 240GB disk 3) I have not gone into partition alignment for two reasons: 1) the article on debian wiki refers to is from a long time ago, 2) blockdev doesn't indicate misalignment (see below): $> sudo blockdev --getalignoff /dev/sda1 0 $> sudo blockdev --getalignoff /dev/sda2 0 $> sudo blockdev --getalignoff /dev/sda5 0 4) For mounting file systems, I have added discard in /etc/fstab and also enabled issue_discards in lvm.conf 5) Enabled deadline scheduler using udev rules as I intend to have two HDDs reconnected. 6) Added vm.swappiness as kernel option in /etc/sysctl.d/local.conf What I want to know at this point is: Is there anything else that is recommended? The section on RAMDISK options on tmpfs, does that help? Lastly, the partition alignment discussion on http://tytso.livejournal.com/2009/02/20/ is from 2009 - is it relevant today?

Can you run logind without systemd or journald? If you have something else that provides the systemd interfaces logind depends on, you can run logind (and timedated, localed, and hostnamed) without using systemd as PID 1.

If you can, then why is it that libpam package dependencies which appear (if I've understood the discussion correctly) to be about functionality now provided by logind are pulling in systemd *as the active init system* automatically? There appear to be two facets to this: First, the dependency on systemd's interfaces is expressed as a Depends entry of the form "systemd-sysv | systemd-shim", so as I understand it "install systemd-sysv" ends up being the default method of resolving the dependency because it's the first entry in the alternation. Second, logind >= 205 has a further interface dependency on systemd (logind <= 204 sets up cgroups by itself; logind >= 205 relies on systemd >= 205 to do it) which the current version of systemd-shim does not yet fulfill: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=752939 -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

I installed a second hard drive, installed Debian, and almost everything works. But I apparently told the installer that the system clock is set to UTC, when it is not (because windows has no real concept of time). So when I boot to windows the displayed time is the actual local time, but when I boot into Debian the displayed time is four hours behind local time. If I do a date -u the time that is displayed is the correct local time. I have modified /etc/adjtime and removed the UTC line, but every time I boot up Debian the line re-appears, and the displayed time is still four hours behind. So how do I tell the Debian system that the hardware clock is set to local time in an effort to compensate for the lessor system's inability to correctly manage time? Thanks, Nelson You can tell windows to use UTC internally (while still displaying local time) see http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Windows/2000/Q_21805674.html Thanks Erwan, but I am afraid I have to leave the windows installation alone. Fortunately I rarely have to mess with windows, and as a general rule I don't lower my standards to theirs, but in this case I have no choice, at least until we can eliminate windows from the equation completely. This problem has been around for a long time: Windows insists on setting the hardware clock to local time. A fix I came up with long ago was to doctor /etc/init.d/ntpd to (re)set the hwclock to UTC on boot. This was on a redhat or opensuse machine, so on a debian machine you'd want to edit /etc/init.d/ntp instead. There wasn't any need to install any additional packages to include this one line in that file. dpkg-reconfigure -plow tzdata as root which will allow you to set the global timezone data for your machine. That way you don't necessarily have to adjust adjtime and can choose which timezone you're in which will also sort out the DST "stuff". Reset the clock using the date command to set the time. date --set=070511352013 Then run hwclock --systohc to set the time in the hardware clock which should then be correct for Windows and Linux.

I wasn't intending you alter the initrd, although you can do that if you
want. For a USB stick (no need to be root):
1. Plug in and use the last few lines of dmesg to find the device name.
Let's say it is /dev/sdc.
2. Make one partition large enough to hold grub's files (~10M) and a
netinst or CD-1 image with '/sbin/fdisk'. Put a filesystem on it with
mkfs.vfat from dosfstools.
/sbin/mkfs.vfat /dev/sdc1
3. Install pmount. Mount this partition:
pmount sdc1
4. Install grub on the stick:
grub-install --boot-directory=/media/sdc1/boot /dev/sdc
5. Determine the UUID of /dev/sdc1:
/sbin/blkid /dev/sdc1
6. Download the hd-media vmlinuz and initrd.gz from
http://ftp.nl.debian.org/debian/dists/wheezy/main/installer-i386/current/images/
and copy them to /boot. Copy your preseed file and a netinst or CD-1
image to /.
7. Write a /boot/grub/grub.cfg like so:
menuentry "Test preseed file" {
search --fs-uuid --set=root UUID
linux /boot/vmlinuz priority=high file=/hd-media/preseed.cfg
locale=en_GB.UTF-8 keymap=gb
initrd /boot/initrd.gz
}
You choose "priority", "locale" and "keymap". I'd start with "priority=low".
Add "shared/ask_device=manual" and "shared/enter_device=/dev/disk/UUID"
to the linux line after you are confident with what you have above.
initrd.gz contains iso-scan. It searches for a Debian ISO on the stick.
When it finds it the partition the ISO is on is mounted on /hd-media.
preseed.cfg is on the same partition so that relieves you of the necessity
of mounting it by hand.

Delays locale and keymap questions (when locale and keymap are put in
preseed.cfg) until after network configuration takes place. Not needed
because the preseeding takes place from the linux line at the start of
the install.
I'm not too sure there isn't a bug in the Wheezy installer which leads
to "keymap=gb" not being acted on with "auto=true". People with a "us"
keymap may not notice it because d-i defaults to a us keyboard anyway.
I'll leave it to you to handle tranferring the USB stick contents to a
CD. :)

Yes, the 'file' utility is a much better indicator of the file type
("file filename.ext"). I haven't seen it written anywhere, but believe
that the same capability is built into the shell, at least into bash.

Such as "data munging with X" where X is awk, perl, python, ruby, or
other programming language. There is even a classic book Data Munging
with Perl that specializes in such things. I tend to use awk for such
things since they can be done as a one-liner fairly easily.

Of course this assumes a simple csv format. If there are quoted
commas in the data then full CSV parsing is needed. But if not then
this works well.

And so for for me with the above. All of those can be done as
one-liners with perl, python, ruby, other too.

With SQLite you don't have a central server. You just have a local
database file. So if you must have a database then I suggest SQLite.
However I don't think you need a database yet at this time.

If you are already sed/grep/awk then stop at awk. :-)
Seriously though what do you want to do that can't be done easily with awk?

Of course! Everything is already readily available to you without

If you like perl then:
perl -F, -lane 'END{print $t} $t += $F[7] if $F[1] == 5'
And similar for other languages. You could even load a full CSV
module if needed.
