Hello,
I need a few explanation about the log files for system messages:
/var/adm/messages and
/var/log/syslog.

As /var/adm/messages is empty on my machine, i need help.
First, i would like to know what the difference between these 2 files is? Do they contain different kinds of system messages?

Do they exist on all unix version? (I know that they do exist on Sun but what about AIX?). Are they always plain text files?

Any answer is welcome, thank you in advance.
