LASTLOG(8)						      System Manager's Manual							LASTLOG(8)

NAME
       lastlog - examine lastlog file

SYNOPSIS
       lastlog [<-u|--user> login-name]
	       [<-t|--time> days] [<-h|--help>]

DESCRIPTION
       lastlog	formats  and  prints  the contents of the last login log /var/log/lastlog file . The login-name, port, and last login time will be
       printed. The default (no flags) causes lastlog entries to be printed, sorted by the numerical UID.

       -u, --user login-name will cause the lastlog record for
	      login-name only to be printed

       -t, --time days will cause only the lastlogins more recent
	      han fIdays to be printed

       -h, --help print a one-line help message and exit.

       The -t flag overrides the use of -u.

       If the user has never logged in the message "**Never logged in**" will be displayed instead of the port and time.

FILES
       /var/log/lastlog - lastlog logging file

CAVEATS
       Large gaps in uid numbers will cause the lastlog program to run longer with no output to the screen (i.e. if  mmdf=800  and  last  uid=170,
       program will appear to hang as it processes uid 171-799).
