Display which distro is installed

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Show one line summaries of all DEB packages installed on Ubuntu based on pattern search

I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name. The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well.

Edit video by cutting the part you like without transcoding.

Examples: The following will take frames starting at 15.2 seconds for a total of 45.9 seconds: $ mencoder -ss 15.2 -endpos 30.7 -oac copy -ovc copy mymovie.avi -o myeditedmovie.avi Keep in mind -endpos is the total time, i.e. the output video in this is 3 minutes 3 seconds in length: $ mencoder -ss 1 minute -endpos 2 minutes 3 seconds -oac copy -ovc copy mymovie.avi -o myeditedmovie.avi
