Suppose you have recorded your console session with "script" command. And then you want to display it via simple "less" command. But wait, you see: (note: by default ls use coloring scheme via command aliasing, so if you don't have it, simply use ls --color) 

ESC]0;mulyadi@rumah:/tmp^GESC[?1034h[mulyadi@rumah tmp]$ ls
ESC[00mESC[00;34mgconfd-doelESC[00m ESC[00;34mvirtual-mulyadi.Bx4b1XESC
How do you make these "strange" characters to appear as color? Use less -r <your script file> and you'll see colors as they originally appear.
