Extract a remote tarball in the current directory without having to save it locally

Create a pdf version of a manpage
Quick and dirty version. I made a version that checks if a manpage exists (but it's not a oneliner). You must have ps2pdf and of course Ghostscript installed in your box. Enhancements appreciated :-)

Push your present working directory to a stack that you can pop later
If are a Bash user and you are in a directory and need to go else where for a while but don't want to lose where you were, use pushd instead of cd. cd /home/complicated/path/.I/dont/want/to/forget pushd /tmp cd thing/in/tmp popd (returns you to /home/complicated/path/.I/dont/want/to/forget)

Make a dedicated folder for each zip file
${f%*.zip} strips off the extension from zip filenames

Encoding from AVI to MPEG format
http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-mpeg.html MEncoder can create MPEG (MPEG-PS) format output files. Usually, when you are using MPEG-1 or MPEG-2 video, it is because you are encoding for a constrained format such as SVCD, VCD, or DVD. To change MEncoder's output file format, use the -of mpeg option. Creating an MPEG-1 file suitable to be played on systems with minimal multimedia support, such as default Windows installs: $ mencoder input.avi -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 \ -o output.mpg -oac lavc -lavcopts acodec=mp2:abitrate=224 -ovc lavc \ -lavcopts vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3

Show git log beautifully
Only show a short of important information inline ( include branch info ), and color this log tree.

Generate the CPU utilization report
Generated the CPU utilization stats with 5 lines /every 2 seconds. Needs sysstat package to be installed prior to use sar.

Pulls total current memory usage, including SWAP being used, by all active processes.

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

SVN script for automatically adding and deleting files
