Here's a usefull perl script to trim the wtmp file,
in case it got too big, which happens sometimes, or got curropted (which also happens often).
You could learn from here how to parse the wtmp file...
but of course for just reading its content always simply use "last" like Neo said....

When I type last oracle I get dates from Nov 28, 2000 all the way back to the beginning of time it seems.

Anyone got experience where wtmp logs get truncated everyday? Though sulog, failedlogin and lastlog seems to be fine.
The server uptime is 18 days running on AIX 5.3. Sorry this seems to be a generic questions but never really encountered before. (6 Replies)
Hi,
Does anyone have a script to truncate the wtmp file.
I want to move older entries in the wtmp to a new file and move it out of var/adm and shrink the size. (4 Replies)

ac - login accounting
SYNOPSIS
/usr/sbin/ac [ -w wtmp ] [ -p ] [ -d ] [ people ] ...
DESCRIPTION
Ac produces a printout giving connect time for each user who has logged in during the life of the current wtmp file. A total is also pro-
duced. -w is used to specify an alternate wtmp file. -p prints individual totals; without this option, only totals are printed. -d
causes a printout for each midnight to midnight period. Any people will limit the printout to only the specified login names. If no wtmp
file is given, /usr/adm/wtmp is used.
The accounting file /usr/adm/wtmp is maintained by init and login. Neither of these programs creates the file, so if it does not exist no
connect-time accounting is done. To start accounting, it should be created with length 0. On the other hand if the file is left undis-
turbed it will grow without bound, so periodically any information desired should be collected and the file truncated.
