Control - M is the end line character when a file has been transferred to Unix systems from Windows system.

Some transfer utilities remove this character.

The MSDOS text file line terminator is two characters - carriage-return (ctrl/M) followed by line-feed (ctrl/J).
The unix text file line terminator is a single character - line-feed (ctrl/J).
Text files transferred from MSDOS to unix without conversion contain an unwanted ctrl/M character just before the end of each record.
Because ctrl/M has no special meaning in a unix text file it can in fact occur anywhere in the record.

@mvsramarao: please follow the link in my last post - it will lead you to a brief description of Control-M, the job- and workload-automation tool produced by BMC, which is most likely the subject of your mails.

ps: your question would have fit better in UNIX and Linux Applications, unless you really ment the terminator character.

You are all correct, and you have to admit the question in its present formulation isnt clear:
Is the thread owner talking of the character he see in his mails or is he receiving mails in his in-box from a user called Control-M?
Even that is strange since the Control-M job scheduler mails under the name of the operator of the job and the standard is usually to the operators themselves in order to correct/reschedule faulty jobs...

Yes, I also assumed since it was written Control M that the application was meant. It is an automated scheduler that runs on a mainframe or a distibuted environment.
