I am not sure what you mean by "not working" - as far as i know the od command is known to work and if this is not the case with you there is something seriously going wrong.

I suppose the "^[" are not literal sequences of "<caret-char><opening rectangular bracket>" but in fact ESC-chars, right?

If so, try something along the following line:

Code:
ESC="^["       # a ESC-char entered literally!
sed 's/'"${ESC}"'[[0-9]*m\]//g' /path/to/file > /some/new/file

and see how far that gets you. Be prepared not to catch all the ESC-sequences at first. You may have to adapt the regex a bit.

I hope this helps.
