NAME
last - display login and logout information about users and terminals SYNOPSIS
last [-a] [-n number | -number] [-f filename] [name | tty] ... DESCRIPTION
The last command looks in the /var/adm/wtmpx file, which records all logins and logouts, for information about a user, a terminal, or any group of users and terminals. Arguments specify names of users or terminals of interest. If multiple arguments are given, the information applicable 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 displays the sessions of the specified users and terminals, most recent first, indicating the times at which the session began, the duration of the session, and the terminal on which the session took place. last also indicates whether the session is continuing or was cut short by a reboot. The pseudo-user reboot logs in when the system is shutdown and when it reboots. Thus, last reboot gives an approximate record of when the operating system instance was shutdown and when it rebooted. This can be used to calculate the availability of the operating system over time. last with no arguments displays a record of all logins and logouts, in reverse order. If last is interrupted, it indicates how far the search has progressed in /var/adm/wtmpx. If interrupted with a quit signal (generated by a CTRL-), last indicates how far the search has progressed, and then continues the search. OPTIONS
The following options are supported: -a Displays the hostname in the last column. -f filename Uses filename as the name of the accounting file instead of /var/adm/wtmpx. -n number|-number Limits the number of entries displayed to that specified by number. These options are identical; the -num- ber option is provided as a transition tool only and is removed in future releases. ENVIRONMENT VARIABLES
Date and time format is based on locale specified by the LC_ALL, LC_TIME, or LANG environments, in that order of priority. FILES

Arguments specify names of users or ttys of interest. The names of ttys can be given fully or abbreviated. For example, is the same as If multiple arguments are given, the information that applies to any of the arguments is printed. For example, lists all of sessions as well as all sessions on the console terminal. The command prints the sessions of the specified users and ttys, most recent first, indicating when the session began, the duration of the session, and the tty on which the session took place. indicates if the session is still in progress or if it was cut short by a reboot. The pseudo-user logs each time the system reboots. Thus, is a useful command for evaluating the relative time between system reboots. If is interrupted, it indicates how far the search has progressed in If interrupted by a quit signal (generated by a Ctrl-), indicates how far the search has progressed, then continues the search. The command searches backwards through the database file to display bad login information. Access to should be restricted to users with appropriate privileges (owned by and readable only by because it may contain password information.

When used with and displays the user's host name as it is stored in the files and respectively. The host name is displayed between the tty name and the user's login time. Limits the report to number of lines. Use file as the name of the accounting file instead of or Use file as the name of the accounting database instead of This option should be used along with the option.
