ksh script, exit status and pipe
I want to execute a command, redirect stderr and tee stdout
e.g.
tar ... 2>foo.err | tee foo.log
however I also want to capture the exit status of the first command
tar ... 2>foo.err | tee foo.log
exitstatus = $?
simply gets the exit status of tee of course
tar ... || exitstatus=$? 2>foo.err | tee foo.log
always sets exitstatus to zero, looks like I need to establish some
precedence but brackets don't seem to help.
Is there an idiom for this?
Maybe I should hide the tar in a function?
Apologies if the above is a FAQ, I've RTFM where M = "Learning the Korn
Shell" and "Unix Power Tools", I'm none the wiser (though opening the
latter is always good for a half hour off-topic diversion).
