RTFM function
Some commands have more information on 'info' than in the man pages

Removes file with a dash in the beginning of the name

check site ssl certificate dates
remotely connects to an https site, fetches the ssl certificate and displays the valid dates for the cert

Alert visually until any key is pressed

Connect to all running screen instances
There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.

Print CPU load in percent
Faster then all other commands here at cmdlinefu with the same purpose.

Remove last line from files recursively
Used this command recently to remove the trailing ?> from all the files in a php project, which has having some unnecessary whitespace issues. Obviously, change *.php to whatever you'd like.

convert unixtime to human-readable with awk
- convert unixtime to human-readable with awk - useful to read logfiles with unix-timestamps, f.e. squid-log: sudo tail -f /var/log/squid3/access.log | awk '{ print strftime("%c ", $1) $0; }

Basic sed usage with xargs to refactor a node.js depdendency

List upcoming events on google calendar
Requires googlecl (http://code.google.com/p/googlecl/) Even better when you wrap this in a script and allow the --date=STRING to be $1. Then you can type: whatson "next Thursday" The date string for UNIX date is very flexible. You can also add --cal "[regex]" to the end for multiple calendars.
