Shell Programming and Scripting

Hi ,

I have special character control M in many of my files as below

ersNet-Telnet-3.03/Makefile.PL100644 21166 144 612 7113770214 135
77 0ustar jayusers## -*- Perl -*-^M
^M
use ExtUtils::MakeMaker qw(WriteMakefile);^M
^M
WriteMakefile(NAME => "Net::Telnet",^M
DISTNAME => "Net-Telnet",^M
VERSION_FROM => "lib/Net/Telnet.pm",^M
dist => { COMPRESS => "gzip", SUFFIX => "gz" },^M
($] >= 5.005 ?^M
(ABSTRACT => "Interact with TELNET port



Is there any script/command to find which all files have these control M characters. I tried doing a grep for ^M in my entire directories and sub-directories but it lists files which do not have ^M characters also.

Thanks in Advance
Mohammed

How you are typing ^M ?

Is it using ctrl+v+m or just "^" + m

Grep should work fine with ctrl+v+m

grep -R ^M * works on FC5

^M is a \r character (0x0d), try od -cx filename to find out what charachters in your file

In script you can also use od -x filename | grep 0d in a loop for each file

Thanks guys..od -x command is working

dos2unix (also called dos2ux) will clean up DOS files -- the (^M) thing you see at the end of every line.
