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.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Kill process by pid
To kill a process in windows by using the PID. Change 10728 to the PID of the process you want to kill.

Find usb device in realtime

Make ogg file from wav file
Make ogg file from wav file

a function to create a box of '=' characters around a given string.
First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4962, cleaned up, shortened, and more efficient. Now a ' * ' can be used as the box character, and the variables get unset so they don't mess with anything else you might have. They marked c++ as a function for this command, but I'm not sure why. Must be a bug.

Display screen window number in prompt
Add this to your $HOME/.bashrc file. It will only set this prompt if it is running inside screen ($WINDOW var is set) Looks like this... $ ion@atomos:~[2]$

Swap a file or dir with quick resotre
This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).

pimp text output e.g. "Linux rocks!" to look nice

Load file into RAM (cache) for faster accessing for repeated usage
Best result when file size less than half of RAM size
