and i try to delete a local snapshot but running this
> sudo tmutil deletelocalsnapshots 2018-01-30-194719
Deleted local snapshot '2018-01-30-194719'

Just for fun i wrote a little bash script to delete them all (which also avoids any typos).
for date in $(tmutil listlocalsnapshots / | perl -pe 's/com.*(2018.*)/\1/'); do echo "deleting $date"; sudo tmutil deletelocalsnapshots "$date"; done
Strangely enough, i can repetitively run that command above and it will always show the same output:

Why are my snapshots not deleting? I am quite low on storage space (13gb of space - the snapshots would not even clear when i had 2gb of free space left)
