  • This shell function takes a single argument, which is used as the base name of the .wav, .timing and .session files created. To create a screencast: screencast test type and talk ... then type 'exit' or to exit the screencast. test.wav will contain the audio from your screencast. test.session will contain text and control characters needed to paint the screen test.timing will contain timing information needed to synch individual keystrokes in test.session with the audio. to play back: aplay test.wav & scriptreplay test.{timing,session} NOTE: because the shell function uses the variable "$!", and bash likes to expand '!' during history expansion, you will need to turn off bash's history before you enter the shell function. This can be achieved using the command set +H

  • If you have multiple displays or monitors the DISPLAY environment variable will tell X where to send the output. This is very handy for setting up a mediacenter at home. You can plugin the computer to the TV and then ssh to the computer and set the DISPLAY as above, then run your program and it will show up on the TV.
