LAST(1)LAST(1)NAMElast - indicate last logins of users and teletypes
SYNOPSISlast [ -N ] [ name ... ] [ tty ... ]
DESCRIPTION
Last will look back in the wtmp file which records all logins and
logouts for information about a user, a teletype or any group of users
and teletypes. Arguments specify names of users or teletypes of
interest. Names of teletypes may be given fully or abbreviated. For
example `last 0' is the same as `last tty0'. If multiple arguments are
given, the information which applies to any of the arguments is
printed. For example `last root console' would list all of "root's"
sessions as well as all sessions on the console terminal. Last will
print the sessions of the specified users and teletypes, most recent
first, indicating the times at which the session began, the duration of
the session, and the teletype which the session took place on. If the
session is still continuing or was cut short by a reboot, last so
indicates.
The pseudo-user reboot logs in at reboots of the system, thus
last reboot
will give an indication of mean time between reboot.
Last with no arguments prints a record of all logins and logouts, in
reverse order. The -N option limits the report to N lines.
If last is interrupted, it indicates how far the search has progressed
in wtmp. If interrupted with a quit signal (generated by a control-\)
last indicates how far the search has progressed so far, and the search
continues.
