Check These Out

Find and copy scattered mp3 files into one directory
This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3) It copies all the files to the "mp3" folder in your home directory. If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"

subtraction between lines
It's allways strange for me to see sed and awk in the same command line if you can avoid it

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

Automatically rename tmux window using the current working directory
Adds a function that runs every time the prompt is rendered. The function grabs the CWD from PWD and issues a command to tmux to change the current window

determine if tcp port is open
Requires netcat.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Real full backup copy of /etc folder
Yes, rsync(1) supports local directories. And, should anything change, it's trivial to run the command again, and grab only the changes, instead of the full directory.

Run a command only when load average is below a certain threshold
Good for one off jobs that you want to run at a quiet time. The default threshold is a load average of 0.8 but this can be set using atrun.

clear all non-ascii chars of file.txt

Deleting / Ignoring lines from the top of a file
Output lines starting at line 2.
