man¶

display a manual page
NAME
    man - display a manual page

SYNOPSIS
    man name

DESCRIPTION
    Prints the manual page for a command. Pages are plain-text files in
    the /man directory, one per command, named after the command in
    lower case. `man dir` prints /man/dir. Works for both /bin programs
    and OS built-in commands. An unknown name prints
    "no manual entry for NAME".

    man is a /bin program (a `cat` with a fixed /man/ prefix), so it can
    also be run explicitly: run /bin/man.bin cat

EXAMPLES
    man dir          the manual page for dir
    man man          this page
    man grep         the regex dialect grep accepts
