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 reboots. Thus,
last reboot
will give an indication of mean time between reboots.
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.
- -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 filename
- Use filename as the name of the accounting file instead of /var/adm/wtmpx.
Date and time format is based on locale specified by the LC_ALL
,
LC_TIME
, or LANG
environments, in that order of priority.
