Clean everything which are usually not needed for your linux (or manybe *nix) machine:
Check and clean Journal files (just delete everything more than 100MB, older than 7days):
journalctl --disk-usage
journalctl --vacuum-size=100M
journalctl --vacuum-time=7d
Check and clean coredump files(if you don't want to check the coredump files):
ls -lht /var/lib/systemd/coredump/
rm /var/lib/systemd/coredump/*
Find the cache files which are more than 30 days old and delete them (these are inside $HOME/.cache folder)
# find ~/.cache/ -type f -mtime +30 -print ## if you want to see those.
find ~ /.cache/ -type f -mtime +30 -exec rm -rf {} \; # # delete those
Clean Code OSS workspaceStorage file - ALWAYS CHECK THE DIRECTORY BEFORE REMOVING THINGS
cd " .config/Code - OSS/User/workspaceStorage/"
# rm -rf *
Clean other browser cache files inside the .config folder:
cd " .config/google-chrome/Default/Service Worker/CacheStorage"
# rm -rf *
cd
echo " \n\nCurrent disk usage:\n"
df -h
du --all -h -d 2 --threshold=50M
