Re: Shell Script Returned Value

[Mark Lundy]

The other thing you could do is tee the output to a file, then process that file. That would allow you to check return codes
and also process the filenames tar spews out. Would be two separate steps and little more code! What you are doing is unusual and, interesting! OK, exactly what are you trying todo! :)

Maybe the following will work:
( tar ..... ; TAR_RETVAL=$? ) | while read ...

the () puts the tar is a subshell, the subshell's output goes to your
loop.

Subject: Shell Script Returned Value

Hello everyone,

I have a small programming question here, which I'm not sure if it's
possible to do or not, but any suggestions would be greatly

appreciated.

What I need is for the following to return with the appropriate exit
status
value ( $? ).

---- Start Code ----
tar -cvzf $dev $dir 2>>$backup_error_report | while read line
do
...(conditions here)...
done
retval="$?"
---- End Code ----

Because I'm piping the 'tar' output to 'read', no exit status value is
returned. Is there any way I could still get tar's return value doing

it

this way?.... If that makes any sense to anyone.

Thanks.
