Identify File with ControlM Characters
Dear Members,

I have a file which contains ControlM characters in it.

I need a command by the means of which i should be able to identify if a file has controlM characters.

How can this be achieved.

Thanks
Sandeep

grep can do that...

Code:
grep '^M' filename

Note: type CTRL+V CTRL+M to get the above.

^M comes when we hold ctrl V and M together. This can be done in vi editor.
How do i print ^M in my shell script.

Code:
CR=`echo '\0015'`        # Carriage Return
grep "${CR}" filename

You could say pipe the grep to "wc" and count the hits.
