commands I’ve never seen or don’t know about. There’s almost nothing in standard POSIX that falls in this category, and a lot of OSS that does. E.g., I use to always reach for fuser until I realized it’s not a base install on many distros, so I switched to lsof which is is, and is also both more powerful and harder to use.
commands I’ve seen before but use so infrequently I forget they exist, or what they’re called. This is sadly a larger set than I’d like.
This is a good list.
There are three kinds of Linux commands:
