Log Rotation related question

vasim38 · 01-23-2019, 03:41 PM

i need to rotate logs daily and i have script working fine.My issue is after log rotation i want different files to be compressed in one single gz. How to achieve this.

eg. /var/log/tmp
-rw-r--r-- 1 root root 0 Jan 23 21:19 abc.log
-rw-r--r-- 1 root root 0 Jan 23 21:19 cdf.log

after log rotation i want both files to be compressed in single file. Can you help me here ?

There are many ways. You can concatenate them to a single file then compress that:

Code:

cat abc.log cde.log | gzip -c > abcde.log.gz

If you need to recover the filenames after decompression, create a tar:

Code:

tar czf abcde.tgz abc.log cde.log

berndbausch : I am asking while executing logrotate script and not in general

This shows how useful it can be to provide more context to questions.

Unfortunately I don't have an answer.

logrotate does have a postrotate option to run a shell script after log rotation.

I thought that was an excellent answer. Two ways to do what the OP asked. Just include either in their script....
