NAME
who - show who is logged on
SYNOPSIS
who
[-imqsuwHT] [--count] [--idle] [--heading] [--message] [--mesg]
[--writable] [file] [am i]
DESCRIPTION
This manual page
documents the GNU version of
who.
If given no non-option arguments,
who
prints the following information for each user currently logged on:
-
login name
terminal line
login time
remote hostname or X display
If given one non-option argument,
who
uses that instead of /etc/utmp as the name of the file containing the
record of users logged on. /etc/wtmp is commonly given as an argument
to
who
to look at who has previously logged on.
If given two non-option arguments,
who
prints only the entry for the user running it (determined from its
standard input), preceded by the hostname.
Traditionally, the two arguments given are `am i', as in
`who am i'.
OPTIONS
- -m
-
Same as `who am i'.
- -q, --count
-
Print only the login names and the number of users logged on.
Overrides all other options.
- -s
-
Ignored; for compatibility with other versions of
who.
- -i, -u, --idle
-
After the login time, print the number of
hours and minutes that the user has been idle.
`.' means the user was active in last minute.
`old' means the user was idle for more than 24 hours.
- -H, --heading
-
Print a line of column headings.
- -w, -T, --mesg, --message, --writable
-
Like
-s,
plus after the login name print a character indicating the user's
message status:
-
- +
-
allowing write messages
- -
-
disallowing write messages
- ?
-
cannot find terminal device
The long-named options can be introduced with `+' as well as `--',
for compatibility with previous releases. Eventually support for `+'
will be removed, because it is incompatible with the POSIX.2 standard.
