Run a program transparently, but print a stack trace if it fails
For automated unit tests I wanted my program to run normally, but if it crashed, to add a stack trace to the output log. I came up with this command so I wouldn't have to mess around with core files. The one downside is that it does smoosh your program's stderr and stdout together.

Rotate all jpeg images in current folder, rename them to EXIF datetime and set files timestamp to EXIF datetime

Merge files, joining each line in one line

Paste OS X clipboard contents to a file on a remote machine
Redirects the contents of your clipboard through a pipe, to a remote machine via SSH.

Remove text from file1 which is in file2 and stores it in an other file
This command compares file2 with file1 and removes the lines that are in file1 from file2. Handy if you have a file where file1 was the origional and you want to remove the origional data from your file2.

Merge video files together using mencoder (part of mplayer)
Using mplayer's mencoder, you can merge video files together. '-oac' specifies the audio encoding (here copy, to just copy and not compress) '-ovc' specifies the video encoding (same thing).

Find passwords that has been stored as plain text in NetworkManager

Show total disk space on all partitions
show off how big your disks are

Find where a kind of file is stored
In this case searches for where .desktop files are stored. The resulted is a sorted list of the top directories containing such files.

continuously print string as if being entered from the keyboard
Cycles continuously through a string printing each character with a random delay less than 1 second. First parameter is min, 2nd is max. Example: 1 3 means sleep random .1 to .3. Experiment with different values. The 3rd parameter is the string. The sleep will help with battery life/power consumption. $ cycle 1 3 $(openssl rand 100 | xxd -p) Fans of "The Shining" might get a kick out of this: $ cycle 1 4 ' All work and no play makes Jack a dull boy.'
