delete files only matching regexp

[tarasglek]

I like this script, but would like to delete video files in my securitycam archive and keep pics. This achieves that.

I can now prioritize deletion of videos over static pics by issuing command in sequence

free-disk --free-bytes 400GB -d --delete-re '.*mp4$' test_dir/
free-disk --free-bytes 400GB -d --delete-re '.*jpg$' test_dir/

Thanks! I'll merge it after I added a test case (might take a few days)

Thanks! Could you rebase?

Hey, rebased on dev. I realized this still wasn't working right on ZFS added, a workaround. Without workaround, i'd ask free-disk to free 1gb, and it would free 12gb. I suspect other CoW filesystems with non-trivial free-space tracking would need this too

Thanks! I merged the regex part renaming the param to --delete-path-regex (to be more explicit) and replacing re.match with re.search cause I thought it was more intuitive not to imply matching at start of path (rather specify ^ explicitly). released as v1.0.0

Before merging the second part (disk usage bug fix), I'll need to add tests first

I added --dry-run and units to debug output to help me debug. Also changed exit code to make chaining more robust.
