No manual entry for set

But when i code

Use the --help flag

set --help

This is a nice link as well: Linux set and unset commands

If I do that in Linux Mint, I get `bash: set: --: invalid option` – AdminBee May 29 '20 at 15:42
@AdminBee, `set --help` would only work in ksh93 and recent versions of `bash` (4.4+). With older `bash`, `help set` would work better. See also `info bash set` (or `info zsh set` for `zsh`'s `set` builtin), and `set --man` (or `set --nroff 2>&1 | man -l -`) in `ksh93`. – Stéphane Chazelas May 29 '20 at 15:43
@StéphaneChazelas thank you, that's good to know (seriously). Still, it was originally meant as a caveat to this answer, and it may be worth including that information in the post. – AdminBee May 29 '20 at 15:45
You are observing a typical Linux problem. `man set` works on a typical `UNIX` system. That man page however does not include information on the `bash` builtin command but just for the default shells. – schily May 29 '20 at 15:52
