Question missing hidden characters
I made a small change to a UNIX script. When I tried to run it I received the following message:
/bin/ksh[11]: ^M: not found
/bin/ksh[13]: ^M: not found
/bin/ksh[39]: ^M: not found
As ^M is a non printing character, I don't know how to discover where it is missing. How can I correct thiis error?

Also, how can I avoid this error in the future?

thank you very much for your help

That looks like something you'd get when your script actually contains carriage returns and Unix doesn't like it. Is it possible that you edited your script with a Windows-based text editor that saved the file in DOS format? Try running dos2ux or dos2unix on your script (might want to make a backup first) and run it again. Just a hunch.

Always edit unix text documents with a "text" editor that defaults to unix line endings. That will help you avoid such scenarios in the future.

The editor you used may provide a means to convert the line endings back to unix.
