I couldn't find a way to do this within the
.plist file, however using newsyslog (rotate log files) instead seems to be the way forward.
- Add the following syntax:
<log filename> [owner:group] mode count size when flags [/pid_file] [sig_num]
- Verify that the configuration file is correct with
sudo newsyslog -nvv
So for example from the question, I'll add the following to
/path/to/logfile.log 644 2 1000 * J
/path/to/another_logfile.log 644 2 1000 * J
- mode: 644 (
root can change it, everyone else can read it)
- count: 2 (maximum number of archive files which may exist)
- size: 1000 (max log file size of 1000 kilobytes)
- when: * (log rotation solely depends on the size)
- flags: J (newsyslog should attempt to save disk space by compressing the rotated log file using
See the newsyslog manual for more information.
