I am not very good with bourne shell scripts, but above you increment LOOP
with
LOOP=$[LOOP + 1]
why won't it work if you do a
FILE=$[FILE + 1]
Also, isn't this statement clobbing your $FILE?
cat $FILE | tr "\r" "\n" > $FILE
If the filenames are numbered 1, 2, 3, 4; can't you just use the LOOP
variable?
(Sytnax is probably wrong)
#! /bin/bash
LOOP_TIMES=$#
LOOP=1
FILE=$1
while [ $LOOP -le $LOOP_TIMES ]; do
cat $LOOP | tr "\r" "\n" > "$LOOP.new"
LOOP=$[ LOOP + 1 ]
done
Which would run all files in the directory (assuming the file names start at
1)
Here is a quick perl script that might work for you
#!/usr/bin/perl -w
$directory = "./";
@ls = `ls $directory`;
foreach(@ls)
{ chop($_);
system ("cat $_ | tr \"\r\" \"\n\" > $_.output");
}
This will take ALL files in directory (including binary and data, opps) and
run then though the tr command and put the output in the same file name but
with .output at the end of it. You might not need the chop command, I
forget. Also check the syntax, and make sure all files in the directory are
plain ASCII text files. Oh yea, make a backup first and use at your own
risk.

Does that include the job market? My job sucks they stuff me in a hole and
force me to work with NT, yuck.
Anyways, hope that helps. Let me know if you need it to do something else.
