C:\>rem display what files have their archive bit set on drive c: (but don't change the bit):
C:\>attr -a- -R --dry-run *.*
C:\>rem display what files don't have their archive bit set on drive c: (but don't change the bit):
C:\>attr -a+ -R --dry-run *.*To verify a release, download the .zip, .sha256, and .asc files for the release (replacing attr-1.6-win32.zip with the release you are verifying):
$ wget https://github.com/rasa/attr/releases/download/v1.6/attr-1.6-win32.zip
$ wget https://github.com/rasa/attr/releases/download/v1.6/attr-1.6-win32.zip.sha256
$ wget https://github.com/rasa/attr/releases/download/v1.6/attr-1.6-win32.zip.asc
Next, check that sha256sum reports "OK":
$ sha256sum -c attr-1.6-win32.zip.sha256
attr-1.6-win32.zip: OK
Lastly, check that GPG reports "Good signature":
$ gpg --keyserver hkps.pool.sks-keyservers.net --recv-key 0x105a5225b6ab4b22
$ gpg --verify attr-1.5-win32.zip.asc attr-1.5-win32.zip
gpg: using RSA key 0xFF914F74B4BB6EF3
gpg: Good signature from "Ross Smith II <ross@smithii.com>" [ultimate]
