I got a log from remote linux computer. It looks like:

But it should be:

The messy codes are terminal control escape sequences, you can use command "infocmp xterm" and "man terminfo" to get more details.
My question is how can I remove these terminal control escape sequences in the file?
Thanks a lot!
I solved this issue using lots of regular expressions according to http://invisible-island.net/xterm/ctlseqs/ctlseqs.html
