Welcome to my world
The aswer is you can check the used size and you can shrink the used space.
journalctl --disk-usage journalctl --vacuum-size=1G
Other Options are
--vacuum-size=BYTES Reduce disk usage below specified size --vacuum-files=INT Leave only the specified number of journal files --vacuum-time=TIME Remove journal files older than specified time
To create a new empty branch in Git, we can use the --orphan command line option
git checkout --orphan
The command above creates the new empty branch and switches into it.
Once the empty branch s created, we can can delete files from the working directory, so they are not committed in to the new branch
git rm -rf .
Now you are in the empty branch without any inherited files or commits.
If you want to push your empty branch to a remote repository, do the following
git commit --alow-empty -m "Init" git push origin
Note, that if you try to merge another branch into the empty one, you will receive the error: fatal: refusing to merge unrelated histories
Use the --allow-unrelated-history option to force the merge into the empty branch.
git merge --allow-unrelated-history
