lastlog(8) -- Linux man page



lastlog - examine lastlog file  


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


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.
.TP 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.  


/var/log/lastlog - lastlog logging file  


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).
