SummaryRe: Backup script

Hello managers,
Iam putting all replies in this mail
Hi,

I beleive I understood the mail. Here is what i think.

Since you are executing the tar from the script itself, it is executed in a
subshell. thus the execution of next statement
continues. You can create a function and move the tar statement into it.
This will hold the execution of Unlock till the
function finishes. This could work out. Refer to sh(1) for details on this.

Modify your script to capture the PID of tar.  Once you have it you can use

pwait (PID) to watch it.

I'm an old csh hack so your syntax may vary....


set PID=`ps -ef | grep tar | grep -v grep | awk '{print $2}'`
pwait $PID
...rest of script

problem was solved after i put "{" after #1/bin/sh and closed it after done
"; }" in the back up script i used also i introduced `date '+%M%H%' to
confirm time in the script.
