Dear all,
I have a rather naive questionabout 'for' loop through a directory.
What happens if the directory is empty?
Let's try:
$ for i in /foobar/* ; do echo $i; done
/foobar/*
Why do I get the string '/foobar/*' and not nothing?
(note that there is no /foobar/ directory on my system)
In such a case, I would prefer having nothing rather than that.
Is there any option or trick to avoid this behavior ?
Best regards
Christophe
