TAR help

[minus0]

How do you check the exit status of tar? if I do a man on tar, I see that an exit status of 0 means that the tar operation was succesfull but I am not able to figure out how to trap this exit status. Any inputs?

doesn't help - I use Korn shell and this site doesn't talk about ksh. any other idea?

it really does not matter what utility you use - the paradigm is the same [if a utility exit codes are 'well-behaved'].

myUtility myArguments

if [ "${?}" -eq 0 ] ; then
echo "must be a success"
else
echo "must be some kind of failure"
fi;

I swear I tried $? and it didn't work but then that was probably one more mistake of mine but now it does return the correct status - thanks guys

 

[vgersh99]

it depends on the shell:

sh,ksh,bash [most Bourne-likes]
${?}

csh,tcsh [csh-likes]
${status}
