Linux Utilities

Personal reference list of Linux programs and packages – biased to my work, interests, and needs when setting-up Linux boxes.

Approximately 1.3k programs (1% of Ubuntu repo), arranged alphabetically.

Sources

Ubuntu repository, GitHub, SourceForge, vendor websites.
Collated over a number of years from Linux magazines, web searches, and repo hunting.

Notes

A tick in the repo column means the package should exist in the main Ubuntu repo. Nevertheless, some packages can be hidden away – these are marked with 'use apt' (apt search <pkg> to search and sudo apt install <pkg> to install).

Some of the programs listed are included by default with Ubuntu-based distros. Nevertheless, they remain, since on some distro installs they are curiously absent.
