Clean build and package caches on Slackware

1. Goal

Recover space without blindly deleting files that may still be needed for rollback or rebuilds.

2. Files and components involved

/tmp
/var/cache
~/SlackBuilds
du
find

3. Operational flow

du -sh /tmp /var/cache ~/SlackBuilds
find old files by age and type
remove only what can be rebuilt

4. Operational verification

df -h
du -sh /tmp /var/cache ~/SlackBuilds
ls -lah ~/SlackBuilds
head

5. Practical notes

On Slackware, it is worth noting the package, version, source, and build output before updating or cleaning.

Writing down where a package comes from avoids a lot of confusion when you have to troubleshoot or rebuild a system months later.

Quick checklist

[ ] Backup or copy of the existing configuration completed
[ ] Files and commands updated as expected
[ ] Local test completed successfully
[ ] Logs or final output verified
[ ] Rollback procedure documented
