Hello.
XZ is a compression format which I like to use, mostly for its good results when compressing text files. And I was seeking to use it with logrotate.
And it’s done now with these 3 lines added in /etc/logrotate.conf :
compresscmd /usr/bin/xz compressext .xz uncompresscmd /usr/bin/unxz
The default compress argument is “-9”, which is working with xz, so no need to edit.
In my servers, logrotate only rotates logfiles in /var/log, so this find command uncompressed GZIP files and compressed them in XZ format :
find /var/log -name “*.gz” | while read filename; do gunzip $filename && xz -vz9 ${filename%.gz}; done
On Debian, the XZ format tools are available in the xz-utils package.
That’s all folks !
