Shell Programming and Scripting

Hi,

My file has this special character "^M"

I would like to remove this characters.

eg:

abc,abc,^M

i tried using sed but doesnt work.

i used octal dump command to see special character it returns following:
015
\r

Appreciate your reply.

Use "dos2unix" on that file.

Tried:

$ dos2unix file

ksh: dos2unix: not found

Also Tried:

sed 's/^M//g' file> file1

The file1 still has the special character ^M

Appreciate reply
