thanks for the reply but this doesn't work.

The one that did the job was:

HTML Code:
CR=$(printf "\r")
ESC=$(printf "\e")
sed "s/$ESC\[[^Gm]*[Gm]//g;s/$ESC%G//g;s/$CR//g" boottest.log

To remove ^M character use (ctrl + v) and (ctrl + M)

sed -n 's/ctrl+v,ctrl+M/ /gp' file1

First, note that new readers might not realize that ctrl+v is intended to mean press the v key while holding down the key marked ctl, ctrl, or control (depending on your keyboard manufacturer).

Second, note that many readers might not realize that you don't want them to type a comma in the search pattern.

And, third, if they figured out both of those, this wouldn't remove carriage return characters; it would replace them with a space character.

And, by using the -n option to sed you throw away completely any lines that did not contain a carriage return character.

Furthermore, this sed script does absolutely nothing to remove the terminal escape sequences that were the half of the problem noted in the original poster's request.
