Daemonize nc - Transmit a file like a http server
Allow to launch nc like a daemon, in background until you still stop it. You can stop it with kill %1 (jobs method) or kill PID. The -k option can force nc to listen another connection, but if you use redirection, it will work only one time. The loop's inside doesn't do anything, but we can imagine to send a message to screen when a connection is established

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

Execute a command without saving it in the history
Yes, by correctly setting the HIST* variables you can make certain commands not saved in history. But that's complicated and easy to make a mistake. If you set HISTFILE= to blank, nothing in your current shell session will be saved in history. Although this is not a precise answer to the subject, but it's very simple.

Replace duplicate files by hardlinks
This variation can handle file paths containing spaces.

list files recursively by size

Remove security limitations from PDF documents using ghostscript (for Windows)
#4345 also works under windows

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)
Friday is the 5th day of the week, monday is the 1st. Output may be affected by locale.

Copy a file using pv and watch its progress
pv allows a user to see the progress of data through a pipeline, by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA. (man pv)

Create a tar file with the current date in the name.

bulk rename files with sed, one-liner
Far from my favorite, but works in sh and with an old sed that doesn't support '-E'
