NAME

       aulast - a program similar to last

SYNOPSIS

       aulast [ options ] [ user ] [ tty ]

DESCRIPTION

       aulast  is  a  program  that prints out a listing of the last logged in users similarly to the program last and lastb. Aulast searches back
       through the audit logs or the given audit log file and displays a list of all users logged in (and out) based on the range of time  in  the
       audit  logs. Names of users and tty's can be given, in which case aulast will show only those entries matching the arguments. Names of ttys
       can be abbreviated, thus aulast 0 is the same as last tty0.

       The pseudo user reboot logs in each time the system is rebooted. Thus last reboot will show a log of all reboots since  the  log  file  was
       created.

       The  main  difference  that  a user will notice is that aulast print events from oldest to newest, while last prints records from newest to
       oldest. Also, the audit system is not notified each time a tty or pty is allocated, so you may not see quite  as  many  records	indicating
       users and their tty's.

OPTIONS

       --bad  Report on the bad logins.

       --extract
	      Write raw audit records used to create the displayed report into a file aulast.log in the current working directory.

       -f file
	      Use the file instead of the audit logs for input.

       --proof
	      Print out the audit event serial numbers used to determine the preceeding line of the report. A Serial number of 0 is a place holder
	      and not an actual event serial number. The serial numbers can be used to examine the actual audit records in more  detail.  Also	an
	      ausearch query is printed that will let you find the audit records associated with that session.

       --stdin
	      Take audit records from stdin.

EXAMPLES

       To see this month's logins
       ausearch --start this-month --raw | aulast --stdin
