Check These Out

Check if a process is running
Send signal 0 to the process. The return status ($?) can be used to determine if the process is running. 0 if it is, non-zero otherwise.

Connect-back shell using Bash built-ins

Query an NFS host for its list of exports

List files with full path
Prints contents of current directory with the full path prepended to each entry. You can add '-type f' if you don't want the directories to show up (for those less familiar with find). I can't believe ls doesn't have an option for this.

Find broken symlinks
Locate broken symlinks in the current directory. Also useful, to remove broken links: $ find . -type l ! -exec test -e {} \; -print0 | xargs -0 rm

Mute speakers after an hour
Mutes the speakers after an hour, in case you fall asleep watching a video...

Quickly graph a list of numbers
Useful when you've produced a large file of numbers, and want to quickly see the distribution. The value of y halfway along the x axis is the median. Simple! Just create the listOfNumbers.txt file with a number on each line to try it out.

Docker: Remove all exited docker container

Cheap iftop
Shows updated status in a terminal window for connections to port '80' in a human-friendly form. Use 'watch -n1' to update every second, and 'watch -d' to highlight changes between updates. If you wish for status updates on a port other than '80', always remember to put a space afterwards so that ":80" will not match ":8080".

Detach a process from the current shell
ignore HUP interruptions
