I added a file with the following content to /etc/logrotate.d:

/var/log/ocmpproxy.log {
daily
missingok
rotate 4
postrotate
touch /root/test.txt
kill -USR2 `ps aux | grep java | grep OcmpProxy | sed 's/\([a-z]*\) *\([0-9]*\) .*/\2/'`
endscript
}

When I run logrotate, (logrotate -d -f logrotate.conf), my process does not receive any signal. Even the /root/test.txt is not created!

If I run "/bin/kill -USR2 `ps aux | grep java | grep OcmpProxy | sed 's/\([a-z]*\) *\([0-9]*\) .*/\2/'`" from the command line my process receives the signal without any problem.

I am new to logrotate. I appreciate any help.
Is that wrong to call shell command in logrotate?

Thanks in advance.

I'm not sure how picky logrotate.conf is, albeit generally a few options are specified outside of the {} configuration brackets.

I would do this;


# rotate 4 is already defined in default options of logrotate.

/var/log/ocmpproxy.log {
daily
rotate 4
missingok
postrotate
/bin/touch /root/test.txt
/bin/kill -USR2 `ps aux | grep java | grep OcmpProxy | sed 's/\([a-z]*\) *\([0-9]*\) .*/\2/'`
endscript
}
logrotate -f /etc/logrotate.conf
