print latest (top 10, top 3 or *) commandlinefu.com commands

wget -qO - http://www.commandlinefu.com/feed/tenup | xmlstarlet sel -T -t -o '<x>' -n -t -m rss/channel/item -o '<y>' -n -v description -o '</y>' -n -t -o '</x>' | xmlstarlet sel -T -t -m x/y -v code -n

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.
