NAME

SYNOPSIS

DESCRIPTION

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

?

--help

Print a usage message on standard output and exit successfully.

--version

Print version information on standard output then exit successfully.
