OPTIONS    [Toc]    [Back]

       Reads information  about  previous  logins  from  filename
       instead of from the accounting file /var/adm/wtmp.  Limits
       the output to maxlines number of record lines.  Limits the
       output  to  maxlines number of record lines. Provides SVID
       conformance, and is equivalent to -maxlines.

DESCRIPTION    [Toc]    [Back]

       The last command displays, in reverse chronological order,
       all  previous  logins and logouts entered in the currently
       active /var/adm/wtmp file. The list of output records  can
       be  restricted  to  maxlines number of record lines if the
       -maxlines or the -n maxlines option is specified. The last
       command also displays logins and logouts by the user specified
 with the name parameter, and logins and logouts from
       terminals  specified with the tty parameter.  The tty terminal
 references can be fully named (for example, tty0) or
       abbreviated  (for  example, 0). For each process, the following
 information is displayed according to session, with
       the  most  recent session listed first: Time session began

       far the search has progressed in the /var/adm/wtmp file is
       provided. If the command is interrupted by a quit  signal,
       an  indication  as to how far the search has progressed is
       provided, but the search continues.

       To obtain information about the mean time between reboots,
       use the word shutdown as the name parameter.
