[Hunki]

I have this file sent to me by someone running windows ( my guess ) , how to can I remove these ^M

DEBUG_ON=true^M
# DEBUG_ON=false^M
^M
# Region we are running in^M

Run dos2ux on them. The pair of newline+carriage return characters are the windows line terminator as opposed to Unix which has only newline. And dos2ux utility will do just that i.e. strip away the carriage return (^M) from the end of each line.

cheers!

vi the file

do the following key sequence
:s/cntl-Vcntl-M//

where cntl-V and cntl-M are single key strokes

If you happen to already be in vi when you notice this, you can fix it immediately without exiting and running the dos2ux tool:

:1,$s/^V^M//
:w

Or something as simple as:
tr -d "\015" < infile > outfile

Thanks for the dos2ux.
