Not knowing what jot(1) was, I read the man page. The synopsis says:
SYNOPSIS
jot [-cnr] [-b word] [-w word] [-s string] [-p precision] [reps [begin
^
[end [s]]]]
^
...so I type in:
$ jot
usage: jot [-cnr] [-b word] [-w word] [-s string] [-p precision]
[reps [begin [end [s]]]]
^ ^
Is my understanding correct that options in square brackets are optional?
