With Gentoo, it is a good idea to keep the install logs
of all installed packages.
In case something goes wrong, a grep in these logs is sometimes very handy.
However, if you set PORTAGE_LOGDIR in your make.conf, you soon have also
thousands of logs of obsolete packages, because each emerge
(successful or not) and also each unmerge (even fast unmerge)
produces a logfile.
The purpose of this project is to eliminate all logs except for the
newest installation logs for the actually installed packages;
the used ones are compressed using brotli, zstd, xz, lzma, bzip2, or gzip,
and selected ones (determined by /etc/logclean.conf) are even shortened.
Moreover, by default all color sequences are removed.
This script takes care in a similar way about your files in
/var/log/elogs(cf. theELOGfeature of portage)/var/log/notices(cf. the unofficial enotice script)
This script can also cleanup your temporary installation directories in
/var/tmp/portage(do not use this in a cron job if portage might be running).
Finally, this script can also shorten the main portage logfile
/var/log/emerge.log
so that only the actually installed packages are logged.
(You might want to keep these for usage with qlop or genlop).
This script is also offers option for a convenient usage from a cron job.
If you have installed app-portage/eix, this script will run slightly faster.
For installation, copy the content of bin/ with executable permission in your
$PATH (perhaps /usr/bin/) and the (possible edited) content of etc/
to /etc/.
To obtain support for zsh completion, you can copy the content of zsh/
to a directory of your zsh's $fpath
(perhaps /usr/share/zsh/site-functions/).
For installation under Gentoo, there is an ebuild in the mv repository
(available by app-select/eselect-repository or app-portage/layman).
