Help decipering a command string

Staci Tribelhorn — Wed, 27 Aug 2008 15:46:54 GMT

Can someone decipher what this command is doing? We've recently upgraded to a new server and since then our sulog appears to be getting truncated daily. In reviewing the syslog, I've found this entry; however, I'm not sure what the command is doing.

/opt/dsau/bin/clog -D -f 'sulog' -l /var/opt/dsau/layouts/syslog_layout -t 100 /var/adm/syslog/syslog.log

Thanks,
Staci

I have only ever seem mention of clog before. It's used for log consolidation. I'll poke around and see what I can find. Maybe someone will know more.

Hi Staci:

Perhaps this manual helps:

So basically it looks like someone was displaying 100 lines from syslog.log that had the word sulog in the line. and had is formatted to the sysylog_layout.
