Convert a videos audio track to ogg vorbis.
Assumes you have ffmpeg and oggenc. Similar to other scripts here, but this time outputting to Ogg Vorbis. I added the variable assignment for a nice output name. This is part of an interactive bash script I have with a few little multimedia tasks in it. http://www.dward.us/software/VSAK.sh

Swap a file or dir with quick resotre
This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).

Generate MD5 of string and output only the hash checksum in a readable format
Generates the md5 hash, without the trailing " -" and with the output "broken" into pairs of hexs.

git pull all repos

run complex remote shell cmds over ssh, without escaping quotes
It executes commands as arguments to ssh, avoiding problematic shell expansions, without the need of writing the commands in question to a temporary file, just reading them from STDIN.

Open (in vim) all modified files in a git repository
The option --porcelain makes the output of git easier to parse. This one-liner may not work if there is a space in the modified file name.

Display the size of all your home's directories
Display the size (human reading) of all the directories in your home path (~).

Display error pages in report format
This command will return a full list of Error 404 pages in the given access log. The following variables have been given to awk Hostname ($2), ERROR Code ($9), Missing Item ($7), Referrer ($11) You can then send this into a file (>> /path/to/file), which you can open with OpenOffice as a CSV

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

To get the CPU temperature continuously on the desktop
There is no need for variables. I also added sleep to reduce cpu usage, however I didn't test it.
