Hi,
I stumbled about another bash problem today:
for item in $(false);
echo $item
done || { echo for failed; }
doesn't fail. I think it's bad that there is no
set -e
like switch which really catches all failures of this kind.
If you want to ignore non zero exit status you can always use || true.
Of course the workaround is obvious: use
dummy_var=$(false)
for item in $dummy_var;
echo $item
done || { echo for failed; }
However you have to remeber this pitfall.
I know that some scripts may depend on the current behaviour.
So what about adding a new switch beeing more strict?
Sincerly
