SYNOPSIS

9       last [-a] [-n number | -number] [-f filename]
10            [name | tty]...

DESCRIPTION

14       The  last  command  looks in the /var/adm/wtmpx file, which records all
15       logins and logouts, for information about a user, a  terminal,  or  any
16       group  of users and terminals. Arguments specify names of users or ter‐
17       minals of interest. If multiple arguments are  given,  the  information
18       applicable  to  any of the arguments is printed. For example, last root
19       console lists all of root's sessions, as well as all  sessions  on  the
20       console terminal. last displays the sessions of the specified users and
21       terminals, most recent first, indicating the times at which the session
22       began,  the duration of the session, and the terminal on which the ses‐
23       sion took place. last also indicates whether the session is  continuing
24       or was cut short by a reboot.
25
26
27       The  pseudo-user reboot logs in when the system is shutdown and when it
28       reboots. Thus,
29
30         last reboot
31
32
33
34
35       gives an approximate record of when the operating system  instance  was
36       shutdown and when it rebooted. This can be used to calculate the avail‐
37       ability of the operating system over time.
38
39
40       last with no arguments displays a record of all logins and logouts,  in
41       reverse order.
42
43
44       If  last is interrupted, it indicates how far the search has progressed
45       in /var/adm/wtmpx. If interrupted with a quit signal  (generated  by  a
46       CTRL−\),  last  indicates  how  far the search has progressed, and then
47       continues the search.
