Check These Out

Keep one instance of an irc chat client in a screen session
This command attempts to attach to existing irssi session, if one exists, otherwise creates one. I use "irc" because I use different irc clients depending on what system I am working on. Consistency is queen.

setup a tunnel from destination machine port 80 to localhost 2001, via a second (hub) machine.
this is handy when the hubmachine is the only machine that can connect to the destination machine (allowed on ip by firewall) and you want to access it from your laptop.

Disable system bell in an X session
Execute this command in a terminal to disable the system-bell during X-session lifetime.

Show all mergeinfo for a svn subtree

Print one . instead of each line
this version only uses shell builtins

SoX recording audio and trimming silence
Records audio from your mic in FLAC (Free Lossless Audio Codec) format, starts only after it detects at least 0.1 seconds of noise and stops after 1 second of silence. You can adjust the percent values (sensitivity) to best fit your microphone and voice (0.1% if you have a great quality mic, higher if you don't, 0% does not trim anything). Useful for speech recognition in conjunction with my previous command titled 'Google voice recognition "API"' (http://www.commandlinefu.com/commands/view/8043/google-voice-recognition-api).

Concatenate video files to YouTube ready output
Takes two input video files and an external audio track and encodes them together to an MPEG-4 DivX output video file with the correct size ready for uploading.

show dd progress
if you need see progress of long dd command, enter subj on other console

Connect to FreeWifi hotspot (France) and keep the connection active
(In French) Connection aux hotspots FreeWifi, et maintien de la connection active

get the oldest file in a directory
reverse the sorting of ls to get the newest file: $ls -1tr --group-directories-first /path/to/dir/ | tail -n 1 Problems: If there are no files in the directory you will get a directory or nothing.
