LAST(1) General Commands Manual LAST(1)NAME
last - display recent on-line session records
SYNOPSIS
last [-f file] [-r] [-n] [name] [tty] ...
OPTIONS -f Use file instead of /usr/adm/wtmp
-r Search backwards only to last reboot
-n Print a maximum of n lines
EXAMPLES
last reboot # When was the system last rebooted?
last ast # When was the last login for ast?

DESCRIPTION
Last Searches backward through the login administration file (default is /usr/adm/wtmp), printing information about previous logins and
reboots. During a long search, the SIGQUIT signal (CTRL-) causes last to display how far back it has gone; it then continues.

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
/usr/adm/wtmp

Our system produce logs when a script is run which may not be daily, the logs have a format: name_YYMMDD.log - both name and .log are consistent, date changes as per the day the script is run.

Howdy all. I have some scripts that read a text file looking for a keyword, then returning all the text until another keyword and puts it into a new file. Problem is, sed returns the entire last line that contains the 2nd keyword, and I don't want it! Here's an example of the sed script line:
