This script as written doesn't do at all what you think it does.  It just
echos the script arguments, splitting them where they contain `\' or `n'.

If you want to iterate for each line in a file, use `read':

while read line
do
        process line
done < file

How exactly does bash `crash'?  Does it core dump?
