UNIX Terminal Session Hijacking Utilities Ttyutils is UNIX/Linux terminal session hijacking toolkit, also a customize and extendible platform.
By create a pseudo terminal to run a program, ttyutils can whole capture the program output data, and control the input to that program.
After program output data been captured, ttyutils can save these data to a encrypted and compression file, late can be play back to reappear the session, or send these data to monitor program at realtime.
Ttyutils will also use these data to create a virtual terminal(just like a terminal emulation (think xterm), but invisible), user can setup screen feature condition match on this virtual terminal to trigger customize action.
the usage of ttyutils is similarity to shell built-in command `exec', so the chief program of ttyutils named ttyexec.
