Mark -
You're right, that's an odd inconsistency. I thought perhaps we could
modify IFS, but it uses space/tab/newline by default, yet it doesn't
seem to be splitting on the space in the first example. (I would
think it should.) These two commands produce identical files
(according to `cat -vet`, which should show me nonprinting
characters):
LIST=*; for i in $LIST; do echo $i >> listout1;done
ls >> listout2
Obviously, there's something in one output that's not in the other,
but I don't know what it is. So ... I don't have an answer for you,
but you might consider using a dash of Perl instead. This snippet
produces what you want, and works with both the output files from the
previous two commands:
open(LIST,"listout2");
while (<LIST>) {
print;
}
Perl splits input on newlines unless told not to.
If you do find a solution to the bash dilemma, please post it!
