Actually, I am piping it through openssl to encrypt it first. That is the reason for the non-conventional output. See here: tar -zcvf - * --exclude-from $EXCLUDES | openssl des3 -salt -k $1 | dd of=$(hostname)-$(date +%Y%m%d).tbz I tried appending " > OUTPUT" to the end in the hope that it would capture the output to a variable with the name OUTPUT but that did not work. So, How should I be doing that? > Another error I noticed is that you provide the --exclude-from after > the '*' which expands to input file names. > Then you can redirect stderr to stdout in order to fetch it using back-ticks: > > tar_stdout_and_stderr=`tar -zcvf out.tar --exclude-from $EXCLUDES * 2>&1` > This is something that I cannot do because of the pipe to encryption. -- Dotan Cohen http://what-is-what.com http://gibberish.co.il Please CC me if you want to be sure that I read your message.
