This lengthy cryptic line will print the latest top 10 commandlinefu.com posts without their summaries. To print also their respective summaries use the following (even bigger) command line:
wget -qO - http://www.commandlinefu.com/feed/tenup | xmlstarlet sel -T -t -o '<doc>' -n -t -m rss/channel/item -o '<item>' -n -o '<title>' -v title -o '</title>' -n -o '<description>' -v description -o '</description>' -n -o '</item>' -n -t -o '</doc>' | xmlstarlet sel -T -t -m doc/item -v description/code -n -v title -n -n
It is recommended to include this line into a shell script to be easily run, as I do myself. You could also use the following URLs to browse the top 3 commands:
wget -qO - http://www.commandlinefu.com/feed/threeup | xmlstarlet ...
.. or all others:
wget -qO - http://feeds2.feedburner.com/Command-line-fu | xmlstarlet ...
PS: You need to install "xmlstarlet" to run it. It is found in Debian APT repositories (apt-get install xmlstarlet) or under the http://xmlstar.sourceforge.net/ URL.

You can also save EXIF information by copying it to temp.jpg:
jpegtran -optimize -outfile temp.jpg <JPEG> && jhead -te temp.jpg "$_" && mv temp.jpg "$_"
first need to Edit the configuration file /home/cicciobomba/.subversion and under the [tunnels] add this line ciccio_diverso = /usr/bin/ssh -p 12345
(This may be specific to bash only.) This transforms the current working directory to all uppercase characters and replaces forward slashes with backslashes, prepending the string with "C:" and appending a single ">". It serves no practical purpose, but may serve as a great practical joke if you can insert it to some victim's .bashrc :-) Show Sample Output
You can also use gawk: ps auxww | gawk '/application/' | gawk '/processtobekilled/' | gawk '{print $2}' | grep -v grep | xargs kill -9
There must be no space between -p and the password
Bind it to a shortcut key, using something like xbindkeys-config (if you do not have xbindkeys: apt-get install xbindkeys xbindkeys-config)
This command is used to verify a sha256sum-formatted file hash list on IBM AIX or any other UNIX-like OS that has openssl but doesn't have sha256sum by default. Steps: 1: Save to the filesystem a script that: A: Receives as arguments the two parts of one line of a sha256sum listing B: Feeds a file into openssl on SHA256 standard input hash calculation mode, and saves the result C: Compares the calculated hash against the one received as argument D: Outputs the result in a sha256sum-like format 2: Make the script runnable 3: Feed the sha256sum listing to xargs, running the aforementioned script and passing 2 arguments at a time Show Sample Output
I needed to convert a screen capture when using Gnome's "recordmydesktop" and convert it to a .wmv for playback in Windows.
