NAME

last − indicate last logins of users and teletypes

SYNOPSIS

last [ name ...  ] [ tty ...  ]

DESCRIPTION

Last searches 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 identical to ‘last tty0’.  If multiple arguments are given, the information which applies to any of the arguments is printed.  For example, ‘last root console’ lists all of "root’s" sessions as well as all sessions on the console terminal.  Last prints 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 on which the session took place.  Last also indicates the session is still continuing or was cut short by a reboot. 

The pseudo-user reboot logs in at reboots of the system, thus entering

last reboot

gives an indication of mean time between reboot. 

Last with no arguments prints a record of all logins and logouts, in reverse order. 

If last is interrupted, it indicates the point to which the search has progressed in wtmp.  If interrupted with a quit signal, (generated by a control-\) last indicates how far the search has progressed to this point, and the search continues.
