The previous log name is used as the base of the output file, which is written to a specified directory with a .txt extension.
The file /etc/acctadm.conf is maintained by the acctadm command, I read the log file names from it, and if there is no log file I don't start one. i.e. you need to manually start accounting with acctadm the first time to decide which logs you want to generate. The command syntax now looks like this:
# ./exdump
Usage: exdump [-vwr] [
-v: verbose
-w: wracct all processes first
-r: rotate logs
-a dir: use acctadm.conf to get input logs, and write output files to dir
-w: wracct all processes first
-r: rotate logs
-a dir: use acctadm.conf to get input logs, and write output files to dir
The usual way to run the command will be from cron as shown
0 * * * * /opt/exdump/exdump -war /var/tmp/exacct > /dev/null 2>&1
2 * * * * /bin/find /var/adm/exacct -ctime +7 -exec rm {} \;
This also shows how to clean up old log files, I only delete the binary files in this example, and I created /var/tmp/exacct to hold the text files. The process data in the text file looks like this:

Since the -w option forced long running processes to write an accounting record they have not finished, and I chose to mark this by showing the duration as -1. One odd thing shown here is that the sched process generated three identical accounting records, this needs some more investigation.
I'm going to run this for a while, and install it on a few other machines including SPARC Solaris 10 and Solaris 8 to make sure its robust.
