That’s what I personally appreciate in a linux environment - it also provides documentation for it’s commands.
You just need to enter the command:
which in your case is:
and you will see the manual page like ( just the first rows are included here ) :
ZIP(1) General Commands Manual ZIP(1)
zip - package and compress (archive) files
zip [-aABcdDeEfFghjklLmoqrRSTuvVwXyz!@$] [--longoption ...] [-b path] [-n suffixes] [-t date] [-tt date] [zipfile [file ...]] [-xi list]
zipcloak (see separate man page)
zipnote (see separate man page)
zipsplit (see separate man page)
Note: Command line processing in zip has been changed to support long options and handle all options and arguments more consistently. Some old com‐
mand lines that depend on command line inconsistencies may no longer work.
zip is a compression and file packaging utility for Unix, VMS, MSDOS, OS/2, Windows 9x/NT/XP, Minix, Atari, Macintosh, Amiga, and Acorn RISC OS. It
is analogous to a combination of the Unix commands tar(1) and compress(1) and is compatible with PKZIP (Phil Katz's ZIP for MSDOS systems).
