DEC OSF/1 Unix / Tru64 log files

1. /etc/syslog.conf defines the system logging directories, e.g.:

    
   mail.debug              /var/adm/syslog.dated/mail.log
   syslog.debug            /var/adm/syslog.dated/syslog.log
   

   The .dated suffix causes a daily log directory dd-mmm-hh:mm to be created. Otherwise the log files will grow undefinitely, unless they are "rotated" as indicated below.
   Whenever /etc/syslog.conf is modified, one has to tell the syslogd daemon to reconfigure:

   kill -HUP `cat /var/run/syslog.pid` # send a "hangup" signal
   

2. The system default logging into /var/adm/syslog.dated is associated with a cleanup cron job.
   If a different logging scheme is chosen, one may use /opt/bin/logrotate.sh
   as a shell script to rename previous versions of the logfiles by appending a version number running from 0 through 5. This way the last week's syslogs are kept.
   Use

    
   crontab -e                     
   # or:
   vi /usr/spool/cron/crontabs/root # OSF/1 2.x,
   # then insert:
   0 3 * * * /opt/bin/logrotate.sh /var/adm/syslog/mail.log  
   2 3 * * * /opt/bin/logrotate.sh /var/adm/syslog/syslog.log  
   ....
   

   to schedule this at 3:00 AM, 3:02 AM, etc.
