Script to Remove Garbage Character
Hello,

Whenever I transfer files between machines, I find a garbage character (^M) being appended to the end of every line of the file.

Can you suggest a script wherein I can eliminate the garbage character.

I tried sed 's/^M//g' < filename > filename1

...but it doesn't work. Also, this being an escape character, does it add more complexity than it would take to eliminate a normal character?

Thanks in anticipation.

transfer in ascii mode
This is common problem if you transfer in binary mode. Try transferring in ascii mode. You can use
tr -d '^M' <file_name
to delete.

run "dos2unix" on that file and it should get resolved.

If you just wan to delete all control chars without having to pipe to a new file and rename it, use:

This will get rid of all the control chars in the file.
Code:
echo '%s/[[:cntrl:]]//g\nwq' | ex filename

Or use
This will just delete the ^M's
Code:
echo '%s/\015//g\nwq' | ex filename
