If you like those, see also, off the top of my head and in no particular order: system_profiler, ioreg[1], networksetup, afconvert, sips, osascript, lsregister[2], apfs.util[3], and, from Xcode, GetFileInfo and SetFile.

All have man pages except lsregister; lsregister with no arguments shows help (for context, lsregister is useful when file icons / associations get messed up).

Pbcopy/pbpaste are huge productivity boosters for me

I have a shell alias so I can just type pb to do pbpaste|pbcopy - easiest way I’ve found to strip formatting and get plain text.

It's a little awkward, but Cmd-Opt-Shift-V is "Paste and Match Style" aka "paste as plain text".

Pro-tip (at least for me): control (^) doesn't change this, so you can just hold all the modifier keys rather than trying to remember which 3 let you paste as plain text.

Pb stands for pasteboard and not for lead. :D
