tar cvf tarfile.tar *
rc=$?

if [ $rc -ne 0 ] then
echo "error bad tar."
else
echo "good tar"
fi

Add additional code as required.

Hi,

You can redirect stout and sterr to a logfile
tar cvf .... > outputfile 2 >&1

then check the logfile for errors(grep) and generate some error in your script using "logger". In this way you errors can be in the syslog file or someother you can define in syslog.conf.

HTH,
Peter

You can simply redirect the output of the tar command to a file by using the ">" symbol and specifying a file name where the output of the tar command will be written
