  • Is sed not easy or elegant? Commented Oct 26, 2014 at 4:51
  • Maybe there is a command line utility that automagically removes the control chars? Commented Oct 26, 2014 at 4:52
  • There is [:cntrl:] pattern and indeed sed 's/[[:cntrl:]]//g' file1 > file2 is first what comes to my mind. You can use also tr, awk, pure bash... but hard to judge which tool is more easy or elegant. Commented Oct 26, 2014 at 4:59

    Oh, from your update I see, that the problem is not with control characters but with characters which are interpreted as control by shell as \e[0m (colors), although I'm not sure if ^M is control or literal in you log. Commented Oct 26, 2014 at 5:02
  • ^M is control char in the log. I tried your sed, it does remove the control chars but not the other bits like [60G[[0;32m Commented Oct 26, 2014 at 5:11
