i have a final question ...

i have a list of directories inside a string.
i want to tar these directories. i wrote this code;

Code:

directories="/home/cumhur/code/scripts /home/cumhur/Desktop/vim71/src"
destination="/home/cumhur/Desktop/compressed"

for i in $directories
do
	tar -cvzf "$destination$date-$i.tar" "$i"
done

what is wrong in the code ?
it gives me this result;

Code:

tar: /home/cumhur/Desktop/compressed-/home/cumhur/code/scripts.tar: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: Removing leading `/' from member names
/home/cumhur/code/scripts/
/home/cumhur/code/scripts/deneme.sh
/home/cumhur/code/scripts/untitled folder/
/home/cumhur/code/scripts/untitled folder/deneme
/home/cumhur/code/scripts/untitled folder/program2.c
/home/cumhur/code/scripts/untitled folder/qwer.sh
.
.

edit: these directories exist.

You are simply trying to do something like

Code:

tar -cvzf "/home/cumhur/Desktop/compressedMon Dec 17 15:28:00 CET 2007-/home/cumhur/code/scripts" "/home/cumhur/code/scripts"

which is obviously wrong. You can first extract the name of the directory from its absolute path and eventually format the date to avoid blank spaces inside the file name. For example

Code:

directories="/home/cumhur/code/scripts /home/cumhur/Desktop/vim71/src"
destination="/home/cumhur/Desktop/compressed"

for i in $directories
do
        dir=$(basename $i)
	tar -cvzf "${destination}/$(date +%Y-%m-%d)-${dir}.tar" "$i"
done

Also, when you are testing scripts you can put an echo in front of some commands: in this way the commands are not executed but will be echoed after the shell has done all the variable expansions (and you will immediately know if the results are what you expected or not).

i think the dir should me more detail define,
you can try this dir=`ls -R youdir`;And i'm unable to describle it
clearly.
