I come from a time when "The System" did nothing for you. If you
missed a period or semi-colon, etc. execution stopped and, if you were
lucky, you got a cryptic error code number with no other explanation.
Hell, my Unix shell programming book is almost 30 years old! And it's
one of the newer ones. ;-)
But thanks for the info anyway.

You don't really need to place semicolons anywhere for a one-liner;
the system does it for you. I've cut and pasted Greg's example into
the command line, and then pressed Uparrow (for history recall):
$ for dir in ab*/; do
> name=${dir%/}
> enfuse --output "$name.jpg" --compression=97 "$dir"/*.jpg
> done
bash: enfuse: command not found
$ for dir in ab*/; do name=${dir%/}; enfuse --output "$name.jpg"
--compression=97 "$dir"/*.jpg; done
and there's your one-liner.

David.

Silly me. I failed to substitute the correct dir name letters in the
script for example "ab" prefix I origninaly posted. Didn"t even notice
until I started troubleshooting 3 hours later. That's what I get for
reading the list a 6:00am. With semi-colons properly placed for a one
liner, it works.

Most likely it means there weren't any matching directories wherever
you ran it. The ab*/ glob will be used literally if it doesn't match
any directories.
If you want to check for that, you can add a test.
for dir in ab*/; do
test -d "$dir" || continue
name=${dir%/}
enfuse --output "$name.jpg" --compression=97 "$dir"/*.jpg
done
You said you had twenty-something directories named ab01, ab02, etc.
So it should have matched unless you ran it from the wrong place,
or unless you lied about your directory names.
But nobody would EVER lie about their directory names in a shell
programming question. Oh, no, never.

I added those semi-colons just as you did to make it one liner correct:
Same error.
Time to troubleshoot. I hope it's just a syntax error somewhere.

Shell Script Help
Hi! All, Want to create a simple, one liner to type in to automate what I've been doing manually: Perform an operation on files in unique, sequential directories, save the results of the operations for each directory with a file name of that directory in the directory the target directories reside in. For example: Directories ab01, ab02 ... ab30 results in output ab01.jpg. ab02.jpg ... ab30.jpg outside of those drectories. There will never be more than 99 directories -- usually a lot less. The actual number will vary job to job. The letters in the directory names will vary job to job, but will remain constant for each job. Only the numbers will sequence. Any help is appreciated. Thanks. B
Automatic Backup Script Help
Hi,
I am trying to setup a basic backup script for a Debian 6.0.5 server and
am wanting to validate the scripts I have so far.
Here is the scenario...
The server has 2 x 1Tb hard drives in RAID 1 config. A third 1Tb hard
drive is used for scheduled rsync snapshots.
I also have 5 x USB 3.0 1Tb hard drives for taking backups off site.
The aim is to plug one of the external hard drives and rsync the
snapshot backup to it automatically.
Using udev rules I now have the hard drives being recognised on plug in
and udev firing off a test script.
As it is not a good idea to block up udev by running the backup script
from the udev rule, I need a staging script to start the backup, but not
immediately.
The backup script is intended to be run 1 minute after the external hard
drive is plugged in, and this is what I have come up with:
Staging Script
==
/data/backups/scripts/start-disk-1.sh
#!/bin/bash
echo /data/backups/scripts/backup-disk-1.sh | at now + 1 minute
Is this the correct way to call the backup script, or is there a better way?
Backup Script
=
Now the backup script needs to do certain things.
1) Mount the hard drive and fail if necessary.
2) Carry out the rsync to the external hard drive.
3) Unmount the external hard drive.
4) Generate a log of the backup process.
4) Send an email with the log as the message body.
I have not figured out how to generate the log.
I am not sure of my script syntax including vs ' vs ` delimiters.
The actual backup script I have come up with is as follows... (I hope
email line wrapping doesn't ruin the script layout.)
/data/backups/scripts/backup-disk-1.sh
#!/bin/bash
# Backup to Disk 1
# Set Variables for Script
backup_description=Disk-1

Is this the correct way to call the backup script, or is there a better way?
It doesn't seem like a bad idea; especially since you get some extras from at
(e.g. mail error output to user) for free. Another approach would be
{ sleep 60; /data/backups/scripts/backup-disk-1.sh }
But I don't see why you even need the sleep.
start_date_time='date +%Y-%m-%d-%H:%M:%S'

the check, instance #2 creates the file… Better would be a proper locking
solution. (sorry I'm not offering one in this reply)

I agree. I suspect using sleep will merely suspend udev operations as well.

That is what I am trying to achieve by the progress file. I have noticed
that sometimes with usb, the device is discovered multiple times. So I
want to prevent multiple instances of the script. I will obviously need
to find a better locking mechanism.

I am lost here. I thought that this would be a simple mountpoint check.
Is there a better way to mount and check if the drive is mounted?

O `pidof rdesktop` descobre o PID do rdesktop e o passa ao wait, que fica aguardando o termino desse programa para dar continuidade ao script. Fiquei curioso. Pelo que eu achava, o bash executava cada linha e esperava o fim da execução para passar pela próxima linha. Assim, a linha wait seria desnecessária, pois a execução do script só continuaria quando o rdesktop fosse terminado - inclusive porque o script poderia continuar de forma diferente em função do código retornado pelo programa, por exemplo. Mas pela própria pergunta original, parece que não é assim que funciona. Mais detalhes? tiago.

I'll have to look into this some more when I have time. A script like
this could be very useful for preparing the formated output from the
program in question. Everyone could just run their data through this
script and then modify some awk commands to get the fields of their
choice. Thanks Fred and Paul for the suggestions.

for this task or outline some steps, I can probably get to my solution.

I now need to covert the elapse time column from the string format
hours:min:sec to a column containing just seconds. I am unsure how to
do this. Can I use command substitution in a sed substitute command?
(sed -e 's//$(command to do math)/') I don't necessarily need a piece
of code but if someone could recommend a bash tool which is well suited
for this task or outline some steps, I can probably get to my solution.
Thanks in advance.
Too bad you don't have a two digit second format, or you could do the following:
HMS='12:34:56'
SECONDS=`date -ud '1/1/70 '$HMS +%s`

I was hoping to make this solution as simple as possible, so that my

ah, I see.

can make the first subexpression match zero or one time. In that

...exactly (though it's 'undef', not null, strictly speaking). And
the nice thing is that Perl doesn't segfault or throw fatal exceptions
in such cases... it just works as expected. If used in a numeric
context, an undefined value will just evaluate to 0, which is typically
what you want.
So, the above s/// statement simply has to be modified as follows
s/^((\d+):)?(\d+):([\d.]+)/sprintf %.3f, $2*60**2 + $3*60 + $4/e
as you may have figured out yourself in the meantime.
Or, taking advantage of the fact that any trailing garbage (':') does
not do any harm to string-to-number conversions in Perl, you can even
save one pair of parentheses ;) -- not universally recommended, though.
s/^(\d+:)?(\d+):([\d.]+)/sprintf %.3f, $1*60**2 + $2*60 + $3/e
(Alternatively, you could of course also write
perl -pe '{} while s/^(\d+):([\d.]+)/$1*60+$2/e'
as another step to achieving obfuscation. OK, I'm being silly.)

With 'find' you can -exec on each result.
For example (note the trailing \; is required to end the exec string.
find will execute all commands until that is found.):
find /usr/src -name .config -exec cp {} /backup_data{} \;
{} will be expanded to the entire path of the found file. The above
line won't work because cp won't create the entire path
/backup_data/usr/src/kernel-source-2.6.9-rja/.config :) You might
want to process {} to create a proper destination.

use find(1) with the mtime flag, e.g.
find /tmp -type f -mtime +30 -exec rm {} \;
will remove all files in /tmp that are more than 30 days old.

Script help...............
Hi debian world...
Im not know very much about scripts so i need some help with one..
Here my situation:
A script will be executed when i call to my linux box... here it is:
/etc/init.d/xringd stop
/root/IP_MAIL
pon incomingcall
/etc/init.d/xringd start|
|
|
This has the -detach option so i can kill it
and the script will continue...
Now, i have problems with /root/IP_MAIL, becouse it try to send me my ip number
before i can get one... this is how IP_mail looks:
1)DAY=$(date +%A)
2)NUMBER=$(date +%d)
3)TIME=$(date +%r)
4)MONTH=$(date +%m)
5)IP=$(/sbin/ifconfig | grep inet | awk '{print $2}' |awk -F: '{print $2}' |
grep -v 127)
6)echo Today, $DAY $NUMBER/$MONTH [$TIME] you have got an ip address: $IP
/tmp/iptemporal.tmp
7)mail -s Identidad: $IP [EMAIL PROTECTED] /tmp/iptemporal.tmp
in [EMAIL PROTECTED] i get:
Today, Monday 26/10 [07:45:12 PM] you have got an ip address:
so how can i make IP_MAIL do 1,2,3,4 and 5 until $IP is not empty ?? (is $IP is
not empty then go on and send the mail...)
Thanks,

Hmmm, What you need, is a script in /etc/ppp/ip-up.d/ to do this, but only
when 'pon incomingcall' is executed.. change your first script thus:
/etc/init.d/xringd stop
touch /tmp/make_IP_available
pon incomingcall
rm /tmp/make_IP_available
/etc/init.d/xringd start
place your second script in /etc/ppp/ip-up.d/ and start it with:
#!/bin/sh
test -f /tmp/make_IP_available || exit 0
...
so if the first script was called, it creates a temporary 0 byte file,
that the second script checks for. If it exists, it mails you with the IP
Address.

RE: Script help...............
Dunno why you are doing it this way so let me ask. Why are you not using the
scripts in /etc/ppp/ip-{up,down}?? The IP address of the connection is passed
to the scripts on login. So you are guaranteed to get a good IP. If this is
not useful for some reason contact me and I can get your script working.
