Hello,
I add script call features to newsyslog. This adds a one field to
newsyslog.conf. When newsyslog processed log file, this can execute
arbitrary program.
Situation to assume:
* For the log file which cannot use signal.
* Cases to do statistical application for log file.
A sample entry of newsylog.conf:
# logfilename [owner:group] mode count size when [ZB] [/pid_file] [sig_num] [/program]
/var/log/foo.log bar:baz640 1 100 * Z - - /etc/foo.sh
'-' is usable as a filler of null field.
I used similar enhanced function from the past. I think that you can
apply this patch for 5-current. In addition, I can prepare a patch
for 4-stable if it is necessary.
I ask for testing and a review of the following patches.
Thanks.
