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. FILES

wcat - printout wtmp entries SYNOPSIS
wcat [-w wtmp|-] [-adX[3|4]] [-s start] [-e end] [-b H[:M[:S]]] [--help] [--version] SYNOPSIS
Wcat provides an easy way to recover trimmed information from wtmp binary files. This tool can be useful for scripts that need only partial information from them. Notice that wcat output is binary wtmp entries so if this information is printed out to a terminal or screen it might mess it up. A better use of wcat would be: wcat | rawtmp -w - OPTIONS
-w wtmp|- Read alternate wtmp file. -X[3] Read tacacs 3.x wtmp format. -X4 Read tacacs 4.0 wtmp format. -d Output time in MMM DD HH:MM:SS date format. -a Print contents of ut_addr (if it exists) instead of ut_host. -s start Display accounting info from `start'. -e end Display accounting info up to `end'. -b H:M:S Show accounting info from the last few hours/minutes/seconds. --help Print this help message. --version Print the version of rawtmp.
