#!/bin/bash

# Should do the same as:
# ls | read f; do echo $f; done
# ...but without starting a new shell

# DOES NOT WORK PROPERLY!

#================
# Alternative #1:

IFS=$(echo);
for file in $(ls); do
    echo $file;
done

exit;

#================
# Alternative #2:

for tmp in $(ls | perl -pe's/\s/\x1/g; $_.=" "'); do
    file=$(echo $tmp | perl -pe's/\x1/ /g; s/\s$//;');
    echo $file;
done;
