last(1)


last -- indicate last user or terminal logins

Synopsis

last [-n number | -number] [-f file] [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. Names of terminals may be given fully or abbreviated. For example last 10 is the same as last term/10. 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 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 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 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>e) last indicates how far the search has progressed so far, and the search continues.

The following options are available:


-n number|-number
Limit the number of entries displayed to that specified by number. These options are identical; the -number option is provided as a transition tool only and will be removed in future releases.

-f file
Use file as the name of the accounting file instead of /var/adm/wtmpx.
