How to purge old versions in equo cache? [Solved]

[nobicycle]

Hi,
Over time I have several versions of packages in the equo cache. I am looking for a command to purge all files there except the latest versions.
"equo cache clean " appears to do nothing.

Thanks to any respondent.

equo cleanup simply removes all downloaded files.
The "cache clean" function is database related. Entropy caches searches and calculations. What you did was clean that data up.

I live in an area where internet is slow and unreliable. I would therefore like to purge the equo cache except for latest versions.

In this example of a file listing, the default sort on name would allow me to clear out the top two files:
qt-qt3support-4.8.0~0
qt-qt3support-4.8.1~0
qt-qt3support-4.8.1~1

However, once versions cross over a power of 10 boundary, the default sort wont work. Secondly I can't parse the version due to variable numbers of dots and minus signs in naming the packages.
Perhaps the equo API would help but I cannot find a full reference.

Ended up with a script that does:
for d in packages packages-nonfree packages-restricted; do
create_array_of_package_names
for package in array_of_package_names do
test if package is installed
if package installed
find the version of this package with the highest version
delete packages of lower version

Code: Select all

find "/var/lib/entropy/client/packages" -atime +30 -type f -delete

This will remove files with access time older than 30 days. However, your filesystem may be mounted with "noatime" and in that case, this wouldn't work as you expect. If this is the case, you could use "-mtime" (modification time), even though it's not the same as "atime".
