Change directories using sudo

Change current working directory with root permissions. Place this snippet in your .bashrc to add a new "sudocd" command: function sudocd { sudo bash -c "cd $1;bash" } Usage: sudocd DIRECTORY Please note that if you will use this command to cd into directories with the permissions allowing only root to be in them, you will have to use sudo as a prefix to every command that changes/does something in that directory (yes, even ls).

Runs previous command replacing foo by bar every time that foo appears

Very useful for rerunning a long command changing some arguments globally. As opposed to ^foo^bar, which only replaces the first occurrence of foo, this one changes every occurrence.

Delete empty, 24-hours-old directories recursively, without consider hidden directories

Downmix from stereo to mono and play radio stream with mplayer

The solution to a year long (and extremely frustrating) problem I've had, caused by the fact that I only have one speaker; this command downmixes the stream to monophonic output, making sure I don't miss any of the music. NOTE: When stream is in .m3u format, a -playlist option is required, as shown below: $ mplayer -af pan=1:0.5:0.5 -channels 1 -playlist radiostream.m3u This command works great with aliases for various channels in .bashrc. Sample below: $ alias radio1='mplayer -af pan=1:0.5:0.5 -channels 1 radio1stream.pls'

removing syncronization problems between audio and video

This assumes that there is a 10.2 sec delay between the video and the audio (delayed). To extract the original video into a audio and video composites look at the command on extracting audio and video from a movie
