LAST(1) UNIX Programmer's Manual LAST(1) NAME last - indicate last logins of users and teletypes SYNOPSIS last [ -f filename ] [ -N ] [ name ... ] [ tty ... ] DESCRIPTION _L_a_s_t will look back in the _w_t_m_p 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. _L_a_s_t 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 ses- sion is still continuing or was cut short by a reboot, _l_a_s_t 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. _L_a_s_t with no arguments prints a record of all logins and logouts, in reverse order. The -f filename option allows the user to examine an alternate _w_t_m_p file. The -N option limits the report to N lines. If _l_a_s_t is interrupted, it indicates how far the search has progressed in _w_t_m_p. If interrupted with a quit signal (gen- erated by a control-\) _l_a_s_t indicates how far the search has progressed so far, and the search continues.
