I tried to delete some images by matching them to a regular expression and I did this in two similar ways by now, both including piping the results of find to rm. First I found all the images that I wish to be deleted with this:
find . -type f -regex ".+-[0-9]+x[0-9]+\.jpg"
Which found a lot of results.
So I tried to delete them like this:
find . -type f -regex ".+-[0-9]+x[0-9]+\.jpg" -exec rm -rf {} \;
And then like this:
find . -type f -regex ".+-[0-9]+x[0-9]+\.jpg" | xargs rm
After both attempts, the find command no longer sees the images that I wanted to delete (when I run the first command again), but ls sees them, and so does Nautilus. Is there some kind of commit I should run in order to actually delete them from the hard disk?
I tried searching the rm man page for "commit" and the find man page for "remove", but haven't found anything significant.
Your regex doesn't match these filenames...
$ touch yellow-zone-etna-36x36.png yellow-zone-etna-615x250.png
$ find . -type f -regex ".+-[0-9]+x[0-9]+\.jpg"
$ # no output
because you have PNGs, you're looking for JPEGs, and you additionally have JPEGs that don't match the regex either.
