For a long time I’ve maintained a memory aid in the form of a list of useful commands which can be used on the command line for Linux, macOS (OS X), BSD, Solaris, etc., so I thought I’d list them in a sticky blog post in case they come in useful for others. Most of these will run on any Unix-type operating system, though I’ve usually indicated where a command is OS-specific. These can be run manually for admin purposes and also scripted for automation purposes.
