Full Discussion: Reading wtmps file
Operating Systems HP-UX Reading wtmps file Post 302966252 by MadeInGermany on Wednesday 10th of February 2016 05:10:24 AM

The -X option is for the /var/adm/wtmps.* files, otherwise fwtmp reads the /var/adm/wtmp.* files.
I have no clue what the extra numbers mean. The man pages are too short (and a bit confusing).
If you want to try the last command, the following extracts most out of the files:
Code:
last -Rf /var/adm/wtmp
last -XxRf /var/adm/wtmps

--
Normally, at least during a system login, wtmp and wtmps are written simultaneously. wtmps has room for more information. So reading wtmps alone should be sufficient.

NAME
utmpx, wtmpx - utmpx and wtmpx database entry formats SYNOPSIS
#include <utmpx.h> /var/adm/utmpx /var/adm/wtmpx DESCRIPTION
The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files. The utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database contains the history of user access and accounting information for the utmpx database. USAGE
Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to inter- act with the utmpx and wtmpx databases to ensure that they are maintained consistently. FILES
/var/adm/utmpx user access and adminstration information /var/adm/wtmpx history of user access and adminstrative information SEE ALSO
