UNIX for Dummies Questions & Answers

// AIX 5.3

I am trying to use .sh after changing it to .ksh
Obviously, it doesn't like the file extension change.
I am seeing a lot of odd characters (^M) like below:

Init_Part2 ()^M^M
{^M^M
AWTRACE "AW SET"^M^M
set | grep -e CFG_ -e OUTDIR_ENV^M^M
AWTRACE "AW SET"^M^M
^M^M
if [ "$OUTDIR" = "" ] ; then^M^M
OUTDIR="." # >AW020<^M^M
fi^M^M
AWTRACE "AW000I OUTDIR=${OUTDIR}"^M^M
AWTRACE "AW000I OUTDIR_ENV=${OUTDIR_ENV}"^M^M
^M^M

How do you remove this odd character (^M)?
The .sh file is large, and manual work is merely possible.

thx much

this is a DOS "return". use "dos2unix" command (depends on your os) to change from DOS to unix file format.

file is in dos format change file format to unix

open file in vim

Code:

:se ff=unix 
:wq!

thats it.

if u dont have vim use vi

Code:

:%s/^M//g

^M - (control-V + control-M)

or

Code:

perl -pi -e 's/^M//g' <filename>
