ttyplay

TTYPLAY(1)						      General Commands Manual							TTYPLAY(1)

NAME

       ttyplay - player of the tty session recorded by ttyrec

SYNOPSIS

       ttyplay [-s SPEED] [-n] [-p] file

DESCRIPTION

       Ttyplay plays the tty session in file, which was recorded previously by ttyrec(1).

       When -p option is given, ttyplay output the file as it grows.  It means that you can see the "live" shell session running by another user.

       If  you	hit  any  key  during  playback, it will go right to the next character typed.	This is handy when examining sessions where a user
       spends a lot of time at a prompt.

       Additionally, there are some special keys defined:

       + or f
	       double the speed of playback.

       - or s
	       halve the speed of playback.

       0      set playback speed to 0, pausing playback.

       1      set playback to speed 1.0 again.

OPTIONS

       -s SPEED
	      multiple the playing speed by SPEED (default is 1).

       -n     no wait mode.  Ignore the timing information in file.

       -p     peek another person's tty session.
