which files can be deleted safe from raspberry?

[BartSr]

Content on my raspberry 3+ sd card is growing

Code: Select all

4,4G	/var
1,7G	/var/log
1,5G	/var/log/journal/9ad0dc29f0a2458cb78c7496645eb372
1,5G	/var/log/journal
1,5G	/var/lib
1,4G	/var/lib/docker
1,2G	/var/cache/apt
1,2G	/var/cache
1,1G	/var/cache/apt/archives
930M	/var/lib/docker/overlay2

Is it safe to delete these files being the biggest ones
info retrieved with command:

Code: Select all

sudo du -ah /var | sort -rh | head -1- > textfile.txt

TIA
Bart

Probably your journal files are growing.
You can restrict that -> search for howto on the Internet.
Cache files can be deleted, but I don't think those will grow fast.
With the right commands you can delete unused / unwanted docker images if you want, again search the Internet.
All the other files should be untouched, most of them are there for a reason.

The command you used displays directories not files.

/var/log should be easy to clean.
And I suppose /var/cache/apt with "apt clean".

This is my safe vacuum cleaner on my RPi:
sudo apt autoclean && sudo apt clean && sudo apt autoremove -y && sudo journalctl --vacuum-time=2d

For journalctl beter put the right instructions in /etc/systemd/journald.conf
Like SystemMaxUse=100M and SystemKeepFree=1G
Then you are done for the future.
