Description
The last command checks the wtmp
file, which records all logins and logouts for information about
a user, a tty line or any group of users and lines.
The argument name specifies a user name and/or tty line.
The command last -t 01 root
would list all root sessions as well as all sessions
on /dev/tty01.
last
prints the sessions of the specified users and ttys,
including login name, the line used, the device name,
the process ID, plus start time and elapsed time.
last
with no arguments prints a record of all logins and logouts, in
reverse chronological order.
The options behave as follows:
-h-
Do not print a header.
-H hostname-
Report on hostname only.
If the -W option is not used to specify the pathname of a
wtmpx(F)
format file, last reads /etc/wtmpx.
-n limit -
Limit the report to limit lines.
-t line -
Specify the terminal line.
-w wtmpfile-
Use wtmpfile instead of /etc/wtmp.
Note that wtmpfile must have the same
format as /etc/wtmp.
-W wtmpxfile-
Use wtmpxfile instead of /etc/wtmpx.
Note that wtmpxfile must have the same
format as /etc/wtmpx.
Files
/etc/wtmp-
