how to generate a random number using a POSIX shell??
as part of a shell script, i'd like to generate a random number (preferably an integer), but i'd like to do it in a POSIX-compliant way. AFAICT, using the $RANDOM variable is not POSIX-compliant -- that variable is not defined in a strict POSIX shell. any other suggestions? perhaps reading a number of bytes from /dev/urandom or something? rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

overview of files/directories for gnome desktop?
i'm trying to throw together a short tutorial for new users on using the stock GNOME desktop that comes with RH 9 and, since i typically have scripts to do most of what i want, i've rarely used the standard icons so i have a couple simple questions that lead into a more complicated question. starting with a brand new user account, and running startx, i notice that i have, initially, three icons in the top left corner: user's Home Start Here Trash but it's not immediately clear what these icons correspond to in terms of actual apps. unlike icons on the panel or in the menus, right-clicking on these desktop icons and asking for Properties doesn't specifically list what the icon represents. if i look in ~/.gnome-desktop, it's easy to see that there are three files that correspond to those icons, but that still doesn't tell me everything about them. if i firther go into ~/.nautilus/metafiles, i can find several more files that complete more of the picture. but, for example, if i double click on, say, Trash, where is the association from that icon to the nautilus file maanger, which is invoked? i guess the more general question is, where i can read something which describes the general layout of the GNOME file and directory hierarchy and how it all hangs together? i've never had any problem customizing my own desktop by adding extra launchers to the panel and so on, but in order to explain how all of this works to new users, i should probably have a much more detailed understanding of what's going on behind the scenes. in particular, i'm curious about the Start Here icon. the getting started guide describes it as a place designed to hold all of the tools and applications you need to access when using your system. technically, is this just a more convenient way to access what's already available in the main menus? is there anything magical about that icon and what it does that's not immediately obvious? and so on. a pointer to the file and directory structure for GNOME would work just fine, thanks. rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

how can i create and manipulate ram disks??
i'm trying to figure out what i can and can't do with ram disks, so let me explain what i've found so far, and perhaps someone can fill in the gaps. by ram disk, i don't mean the boot-time initrd image. i mean setting aside an arbitrary amount of RAM, formatting it as an ext2/3 filesystem, mounting it, filling it with files, and then having smokin' fast access to those files. (as an aside, i wanted to test this by creating a ram disk big enough for the kernel source directory, to see just how much faster a kernel build would run.) so, under RH 9 and with the 2.5.72 kernel, i can see the kernel option for RAM disk support, and a default size of 4096 (kilobytes, or 4M). from what i've read, i can create a number of ram disks corresponding to /dev/ram[012345...], by doing the following: # dd if=/dev/zero of=/dev/ram0 bs=1024 count=16 for a tiny ram disk of 16k (supposedly). so what actually happens? if i try to create an ext2 filesystem on it: # mke2fs /dev/ram0 it works, but it's obvious that it's 4M in size -- the default. i didn't *ask* for the default size, i was hoping i could pick the size myself. but i get 4M anyway. (i can mount that filesystem, and df shows the same thing: 4M). the same thing happens no matter what size i use for dd, until i try to go over 4M, at which point, at the 4097th write (just past 4M), i get No space left on device. in short, no matter what i ask for, i'll get a 4M ram disk. so, the questions: 1) is there any way to create a ram disk of an arbitrary size, regardless of the kernel config value for default size? 2) once i create a ram disk, is there an indicator that tells me that such a thing exists? i mean, free will show me that there's less free space, but that's about it. is there maybe an entry under /proc keeping track of ram disks? you know ... maybe /proc/list_of_ram_disks?? :-) 3) once i create one (even if i'm still stuck with 4M), how can i manually release it? and again, is there a way to verify the return of that ram disk space to the OS? rday -- Robert P.

WRT my example of building a kernel, i realize that the linux kernel is amazingly efficient, but during a typical kernel build, there is constant disk activity. i was interested in setting up the source tree as a ram disk and at least benchmarking. it may be that there's little advantage, but i'll never know until i try. If your RAM disks are using all of you memory, you may end up swapping your programs like crazy. Anyway, all free memory is used by the kernel for buffers, making RAM disks fairly useless. again, until i can benchmark it, i'll never know if there's an advantage. and, as i said, when i do a standard kernel build, there is a fair amount of HD activity, so there's certainly *potential* for reducing disk activity. rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

In single user mode, a root shell is opened on /dev/console. good to know. ... from the file. So inittab is not required but nor is it ignored. On some of my older systems I've overiden this with... ~:S:wait:/sbin/consolechooser ... where consolechooser is a script I wrote to deal with some serial consoles that wouldn't behave themselves. With runlevel 1 your box still needs to have some basic funtionality, in run level S, nothing really needs to work except /sbin/init and /bin/sh... it's basically one step up from booting with init=/bin/sh ... using runlevel S instead of the init= hack (assuming S works) really just means you don't have to reboot the system to go back to a 'real' run level. just to clarify a few things i probably didn't cover clearly in my first post, it's fairly obvious what happens when you move between numbered run levels -- any of 1,2,3,5 -- with the init command. if you're, for example, in level 3, and type init 2, init consults /etc/inittab, which causes all of the K and S scripts in /etc/rc2.d to be invoked, etc, etc. in addition, there is the runlevel command, which prints the previous and current runlevels, so that if you just changed from 3 to 2, the output will be 3 2. if you just booted, though, the runlevel output will be something like N 3, since there *was* no previous runlevel. however, run level s (or S) is different since it isn't defined in /etc/inittab. i was initially a bit confused when, from run level 3, i typed init 1 and, after all the service shutdown, the runlevel command printed 1 S. that was a bit odd, i thought, since i never *asked* for single user mode, but it became clear when you look in /etc/rc1.d and notice that, after all the K scripts, the two S scripts are S00single (go to single user mode) and S17keytable. so, technically, going to run level 1 does take you eventually to single-user mode. but it's not clear if it's a good idea, from say run level 3, to type init s to go directly to single-user mode, since none of the /etc/rc1.d scripts will be run, and all your services will still be running (go ahead and try it, it doesn't seem to hurt anything). from what i read, going directly to single-user mode in this way is not recommended, and is supposed to be used only by other scripts or utilities. when you *boot*, however, it's fine to choose either run level 1 or, in the more extreme case if you've toasted your /etc/inittab, run level s. ok, i think it all makes sense now. rday -- Robert P.

more emergency booting -- emergency mode and init=/bin/sh
(just to complete a doc i'm writing on trouble shooting and emergency booting, my final experiments when even booting to single user mode or run level 1 is not going to work.) two even more minimal booting scenarios i've just tested are booting with the emergency word appended to the boot line, or init=/bin/sh. so what's the difference? (and feel free to fill in the inevitable holes here.) emergency mode - Section 9.4 of the RH 9 Customizaation discusses booting to emergency mode, by simply appending the word emergency to the kernel line at boot time. if you try this, you'll be prompted for the root password to actually go into maintenance mode, at which point, you have a single shell on VC 1. so what can you do here? first, mount shows (at least in my case) only two actual mounts (so this is a good scenario if the root filesystem is good, but some of your others are toast): # mount /dev/hda1 on / type ext3 (rw) /proc on /proc type proc (rw) and that's it. but if you try to see what's running with ps, you get a complaint that /proc is not mounted, that you should make sure you have a line for /proc in /etc/fstab, and that you have to mount it manually with: # mount -t proc /proc /proc it's a bit odd that mount shows /proc is mounted, and i *do* have such a line in /etc/fstab (as we all do, i'm sure), but you still apparently have to mount it manually, so i do, at which point ps shows me: 1 init ... about a dozen more ... 15 bash 55 ps so in emergency mode, init was started, and i have the single shell i can work at. fair enough. in this mode, i can manually mount any of my additional filesystems, but oddly, they don't show up as being mounted with mount or cat /etc/mtab. however, they *are* listed in /proc/mounts. go figure. oddities with the docs --- the Cust Guide claims that emergency mode is useful in that init files are not loaded, and it can be used if init is corrupted or not working. that's a bit odd, since init was definitely started for me here, and i'm not about to trash /sbin/init to see what happens. anyone know if emergency mode can handle a damaged /sbin/init? also, section 9.4 claims that the root filesystem is mounted read-only, but that wasn't true in my case. anyone care to clarify either of these points? init=/bin/sh mode an even more minimal boot scenario is to boot by appending init=/bin/sh, good if you've really trashed your /sbin/init program, since this tells the kernel to start a shell instead of the normal init program. the differences here from emergency mode are that you don't get prompted for the root password -- you just get dumped into superuser maintenance mode. you get all the same weirdnesses as with emergency mode, as in having to mount /proc and so on. but once you do, running ps shows: 1 sh ... 14 kjournald 47 ps which just verifies that, yes indeed, sh was invoked as process 1 instead of init, as one would expect. at that point, this looks very much like emergency mode, at least superficially. rescue mode -- both of the above still require a working root filesystem, at the very least. if you don't even have *that*, you're pretty much forced to boot from, say, the CD-ROM in rescue mode, and fix things from there. so, as i read it, in order of getting more desperate and needing a more minimal configuration to get your system running, * single-user/run level 1 * emergency mode * init=/bin/sh * rescue mode off of the CD any clarifications anyone wants to add? rday p.s. i didn't get into using root/boot floppies or other stuff like that, which would give you even more options. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list

what's the fundamental differences between runlevels [sS] and 1?
rather than being sloppy and continually fudging the distinction between run level s/S (single-user mode) and run level 1, i'd like to really appreciate the differences. first, given that it's common to shut down from multi-user mode to what most people call single-user mode, most people will type init 1. so far, so good. this will, based on the contents of /etc/inittab, kill the services referred to in /etc/rc1.d and, at the very end, run two start scripts: S00single S17keytable so, from this perspective, moving to run level 1 effectively shuts down services and just moves to single user mode (throwing in the keytable script at the end). however, running init s is quite different, since it bypasses the shutting down of services. according to the init man page, you're not really supposed to run init s manually, and i can that's a reason why. i tried it from run level 3, and not surprisingly, none of the services were terminated. what about the difference between going to run level 1 as opposed to run level S at boot time, by editing the boot line at the GRUB prompt? if you go to run level 1, that will eventually cause a read of /etc/inittab to see what's involved in going to that run level. again, so far, so good. but what about going to run level s? /etc/inittab doesn't define what to do with that run level, and the man page for init seems to suggest that you can go to s without the need for /etc/inittab. this is useful to know if you trash your /etc/inittab file, and it suggests that you can get around this by going to run level s at boot time, then repairing/ restoring /etc/inittab. but not so fast. i tried that, and it seemed clear that, even booting to run level s, the file /etc/rc.sysinit listed in /etc/inittab was being invoked, so /etc/inittab appears to still be necessary. anyway, you get the idea. i just want to appreciate the subtle (and not so subtle) differences, and when to use each. rday -- Robert P.

Basically, I'd like some ideas for partition sizes. Say if I have a 20GB drive what would be a suitable, good partition layout, keeping in mind I'd like to do a complete full install. here's a cheap trick i've used for a while. as a first-time throwaway install, do a full install into one humongous, single root partition. once that's done, boot, then # cd / # du -s * this will give you a good idea of what you're looking at in terms of directory usage. note particularly the size of /usr -- a full install will normally take 4-5G just under /usr alone. note that all this is in aid of creating fixed partitions. instead of that, just choose to use LVM at install time, and you can manipulate your partition sizes at will later on. from what i've seen, assuming that LVM is a solid, stable product, there's little reason not to start using it. rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list

It is really not that difficult and the time spent getting it right would pay for it on the first install. I have some links somewhere. If you like I can try to dig them up. With your skills you should be able to knock out a working version in half a day or so. The kickstart list is good for working on stuff like this as well. the above is pretty close to what i did some time back when i was teaching for a major client in texas. they had a classroom i would get access to about an hour before class started on the first day. all seats already had a set of red hat CDs, so what i brought was a kickstart floppy with an appropriate ks.cfg file. one at a time, i'd start a kickstart install at each seat, removing the floppy after it had done its job (about a minute or so), and move on to the next seat. once they were all installing, i'd go for coffee, come back in a while to swap CDs. yes, i know i could have burned custom CDs with the ks.cfg file right on the CD, but it didn't seem worth it. if i ever wanted to make changes, it was way easier to just make a new floppy than a whole new set of CDs. rday p.s. if you're feeling ambitious, you can have a laptop with the CD ISOs on it, and use that as a network kickstart server, make things go even faster. i did that a couple times as well. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
RH 9 -- a couple more questions and observations
1) since www.osnews.com already has a review of RH 9, does this mean that it's set in stone, and that no more adjusting or updating will be done? just curious. 2) if it's a finished product, can nvidia drivers be far behind? (he asks, tongue firmly in cheek.) 3) even if the product itself is not available yet, what are the chances of seeing release notes so we at least know what's coming down the pike? just so we can get a head start on mental preparation. rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list

Red Hat Linux 9 | Get the latest Linux early (fwd)
Red Hat list admin: A number of folks received the following on the Red Hat mailing list recently. The overwhelming evidence is that it is spam, given the return address of redhat.chtah.com. If this is indeed what happened, it seems appropriate to bar all *.chtah.com postings to any and all red hat mailing lists, yes? The links contained in the message are a *clear* attempt to get subscribers to sign up for a completely bogus service, with the proceeds going directly to chtah.com. The faster this domain can be blacklisted, the less chance there is of someone being fleeced.

RH 9: ok, so i overreacted ... but i'm still miffed
ok, so it seems that that first mailing to the RH list was legit after all, so i'm left looking a little sheepish. but i'm still somewhat peeved about how this was done -- unspeakably clumsily. that initial posting was more confusing than anything else. rather than being even remotely informational, it left most scratching their heads, wondering, RH 9? what happened to 8.1? is this spam? is that a typo? certainly, the fact that most people were confused shows that it was *very* badly presented. it's *still* not clear why the jump to 9. one would think that someone at RH would have had the sense to predict that most serious red hatters would want to know about that, yet there was no explanation. and, more to the point, that posting was pure spam. it provided no information, answered no questions -- just announced RHN for red hat 9, and click here to join and give us some of your money. the disclaimer insisted that i got it because i had opted in to get info. i don't recall ever opting in, unless they're talking about the official red hat mailing list, and i joined that one because i wanted to get real information. that posting didn't even vaguely qualify. this whole thing was really poorly done. rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list

at that point, is it really 8.0 anymore, regardless of

a better question might be, why do you need to know this

Hi,
now it works, but because of the '*'.
now i want to remove the leading abc from all files in my directory.
i tried this:
for i in *; do mv $i `echo $i | sed s/abc//`; done
but it doesn't do that.
i always get the error, that the last arguement must be a directory!
I guess, the reason are the white spaces in the names.
perhaps the expression `echo $i | sed s/abc//` also have to
be set in '' or so, but it doesn't work this way.
please help
Single quotes ' are treated literally by the shell interpreter. i.e. no
filename expansion. With double quotes, your variables are expanded prior to
being used. So...
for i in * ; do
mv $i `echo $i | sed -e 's/abc//'`
done
Note: Your example has not dealt with filenames that do NOT contain spaces.
rather than going to the trouble of firing up sed, you can use
the pattern-matching operators built into the shell:
${var#string} # discard shortest prefix matching string
as in,
${i#abc}
will return the string corresponding to the contents of $i,
with a prefix of abc deleted. if the prefix isn't abc,
no change.
check out:
${var#string}
${var##string}
${var%string}
${var%%string
rday
p.s. just to clarify, you would do:
mv $i ${i#abc}
p.p.s. note that string in all of the above can be a
wildcard pattern as well, making it really powerful.

Hi,

But what is about:
${var##string}
${var%string}
${var%%string}
What means the double #, the single and double #?
Please explain me in some words! Thanks!
Is there a man page with this information?
these are internal *shell* constructs, so you would find
them in the man page for bash.
respectively, they are operators which will *remove*, and return
to you what's left, after removing from the variable value:
1) the shortest prefix matching the pattern
2) the longest prefix matching the pattern
3) the shortest suffix matching the pattern
4) the longest prefix matching the pattern
example:
$ filename=/a/b/c/fred.c
$ echo ${filename%.c}
/a/b/c/fred
$ echo ${filename##*/}
fred.c
... and so on. and they're blindingly fast since they're built
into the shell.
rday
p.s. i just typed in the above from memory -- here's hoping there's
no typoes, but i'll let you play with them.
