[Solved] Removing Colors and ^M in a log file

Hi,

I'm trying to send a log file to mailx as a "Body Message" but since the file contains so many control and color characters it's making an attachement out of it instead of putting it in the body.

The file looks like this:
HTML Code:
Bringing up loopback interface:  ^[[60G[^[[0;32m  OK  ^[[0;39m]^M^MŽ
 19 Bringing up interface eth0:  ^[[60G[^[[0;32m  OK  ^[[0;39m]^M^MŽ

I've tried the following with no success.

cat boottest.log | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[mGK]//g"

I then did a dos2unix but this remains at the beginning

^[%G▸ ▸ Welcome to CentOS·Ž
2 Starting udev: ^[%G[ OK ]^MŽ

and even after the dos2unix one ^M remains in the file because it's in the middle of the text.

Don't take into account the line numbers, this is only my text editor setup.

Any help would be appreciated.

Do you have dos2unix and have you tried that?
Code:
dos2unix infile

Yes As mentioned I did try that on top of the sed command with no success

Try some like this:
Code:
awk '{gsub(/\^M|\^\[\[[0-9]*G\[\^\[\[0;32m|\^\[\[0;39m\]/,x)}1' file

If you open vi specify a path to a file that does not exist, vi will create a new, blank file at that location in the filesystem and open it.
