I'm trying to add a debug option to a script of mine. Normally I want to hide any output, like warnings etc, so I put
>/dev/null 2>&1 behind a lot of commands.
Now, when I want to debug my script, I would have to manually remove those, or put every command inside an
if ... fi testing for a
I thought putting
>/dev/null 2>&1 inside a Variable (
$REDIR) and writing
command arg1 $REDIR would do the trick. If I want to debug, I would only need to leave
But a short test on my shell showed me, that it won't work that way:
~$ echo "bla" >/dev/null 2>&1 ~$ REDIR=>/dev/null 2>&1 ~$ echo "bla" $REDIR bla ~$
>/dev/null 2>&1 didn't work either for obvious reasons.
So why does my idea not work here? Did I misunderstand something about putting commands etc. into Variables and calling them?
