Reclaim disk space removing unneeded localizations
localepurge is a small script to recover disk space wasted for unneeded locale files and localized man pages. It will be automagically invoked by dpkg upon completion of any apt installation run. You have to define the locale directory names you want to keep from removal after each apt installation run in the /etc/locale.nopurge configuration file. Unless localepurge has been adequately configured, the system's localization files won't be touched at all.
The contents of following directories will be affected from removals:
The localization files you actually need and which you want to be preserved on your system can be easily configured by running the following command:
The configurable options consist of toggling verbose output, reporting a summary of freed space, and deletion of localized manual pages in addition to locale files. All actions are specified in the /etc/locale.nopurge configuration file.
For detailed debugging the commandline switch -debug or just a short -d instead are available for usage. For verbose output the commandline switch -verbose or just a short -v can be added.
Please note, that this tool is a hack which is not integrated with Debian's package management system and therefore is not meant for the faint of heart. Responsibility for its usage and possible breakage of your system therefore lies in the sysadmin's (your) hands.
Please definitely do abstain from reporting any bugs blaming localepurge if you break your system by using it. If you don't know what you are doing and can't handle any resulting breakage on your own then please simply don't use it.
All locale directories containing a subdirectory named LC_MESSAGES which are either commented out or not even listed at all in /etc/locale.nopurge will be irreversibly deleted. The only way to reinstall any lost locales is a complete reinstallation of all the Debian packages containing them. See /usr/share/doc/localepurge/reinstall_debs.sh for a recipe. Alternatively you can reconfigure it with dpkg-reconfigure(8) to prevent locale files from being purged during subsequent runs of apt.
This program does interfere with the Debian package management and does provoke strange, but usually harmless, behaviour of programs related with apt/dpkg like dpkg-repack(1), debsums(1), reportbug(1), etc. If you need to have any package in its full integrity so that e.g. the formerly mentioned programs work as designed by its author and as expected by you, simply deinstall localepurge temporarily without purging its configuration and reinstall the packages you need in their fully integral state. When you are done with what you needed the integral packages for simply reinstall localepurge again.
Administrators of systems with short disk space should have a look at both the deborphan and debfoster packages. Especially debfoster can work wonders for your scarce disk space!
localepurge and its accompanying manual page was written for the Debian GNU/Linux system by Paul Seelig <[email protected]> with major contributions from Gustavo Noronha Silva <[email protected]> and Francesco Potortì. The author sincerely hopes that some day further development of Debian's great package management system will make localepurge fully obsolete.
