Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Sort a character string
Sorts a character string, using common shell commands.

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

a short counter
Maybe you know shorter ?

Rescan partitions on a SCSI device

list any Linux files without users or groups

Find the package that installed a command

find the biggest files recursively, no matter how many
This command will find the biggest files recursively under a certain directory, no matter if they are too many. If you try the regular commands ("find -type f -exec ls -laSr {} +" or "find -type f -print0 | xargs -0 ls -laSr") the sorting won't be correct because of command line arguments limit. This command won't use command line arguments to sort the files and will display the sorted list correctly.
