Large Unixware 7.01 Syslog file
I have a very large syslog file on a Unixware 7.01 system. Can I delete the syslog file and will Unixware 7.01 recreate it? If not, what is the best way to clear the syslog file to reduce its size?

This is on a Sun box, but the principle is the same... (remember to archive syslog if you require it: cp ./syslog ./syslog.archive; gzip ./syslog.archive)
Code:
# ls -lar
total 14
-rw-r--r--   1 root     sys         2653 Aug 10 19:27 syslog.0
-rw-r--r--   1 root     other        758 Aug 15 12:29 syslog
-rw-r--r--   1 root     other        240 Aug  9 11:32 sysidconfig.log
-rw-------   1 root     sys            0 Aug  9 11:05 authlog
drwxr-xr-x  31 root     sys          512 Aug 10 18:03 ..
drwxr-xr-x   2 root     sys          512 Aug 14 03:10 .
# ps -ef | grep syslogd
    root   179     1  0   Aug 15 ?        0:00 /usr/sbin/syslogd
    root 17250 15626  0 12:37:40 pts/5    0:00 grep syslog
# cat /dev/null > ./syslog
# ls -lar
total 12
-rw-r--r--   1 root     sys         2653 Aug 10 19:27 syslog.0
-rw-r--r--   1 root     other          0 Aug 16 12:37 syslog
-rw-r--r--   1 root     other        240 Aug  9 11:32 sysidconfig.log
-rw-------   1 root     sys            0 Aug  9 11:05 authlog
drwxr-xr-x  31 root     sys          512 Aug 10 18:03 ..
drwxr-xr-x   2 root     sys          512 Aug 14 03:10 .

If the file isn't truncated right away, you might need to
kill -HUP <syslogd_pid_here>

Cheers

From the /var/adm directory, first I suggest making a copy of the file:

cp syslog syslog.old

Then you can clear the file using:

> syslog
