ttyrec: Record Terminal Session in Linux

Overview :

 

ttyrec is a tty(terminal) recorder  in unix like operating system & recorded data can be played back with the help of ttyplay command.ttyrec is just a derivative of script command for recording timing information with microsecond accuracy as well. It can record emacs -nw, vi, lynx, or any programs running on tty.

 

Installation on Ubuntu :

 

# sudo apt-get install ttyrec

 

Installation on RHEL 6.X / CentOS 6.X / Fedora

 

First Download the ttyrec rpm package using wget command  and install using below mentioned yum command.

# wget ftp://ftp.pbone.net/mirror/ftp.turbolinux.com/pub/TurboLinux/stable/tested/Desktop/10/i586/ttyrec-1.0.6-1.i586.rpm

# yum localinstall ttyrec-1.0.6-1.i586.rpm

 

 

Now start Recording using ttyrec command :

 

Open the terminal type the below command and when you want to stop the recording type exit.

# ttyrec

 

When we run the above command recording of terminal session will start and when you type exit, recording will be stopped and a file name “ttyrecord”  will be created in the current directory.

 

 

Now Play the recorded sesssion using ttyplay command

 

# ttyplay ttyrecord

 

commonly used options in ttyplay :

 

  -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.

 

We can also change the speed by using special keys like :

 

+ 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.

 

 

Measuring the time of recorded data :

 

Using ttytime command we can determine the time of recorded data in seconds.

#  ttytime ttyrecord

14  ttyrecord
