Keybase proof

I hereby claim:

I am whomwah on github.
I am whomwah (https://keybase.io/whomwah) on keybase.
I have a public key whose fingerprint is B08A 48C6 5AAB 9463 8B53 11D0 A216 9097 FE9D 4B5B

To claim this, I am signing this object:

Must include one number, one upper and lower case letter and be between 8 and 40 characters

/^(?=.*\d)(?=.*?[a-z])(?=.*?[A-Z]).{8,40}$/

Use the xattr command. You can inspect the extended attributes:

$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms
com.apple.quarantine
and use the -d option to delete one extended attribute:

$ xattr -d com.apple.quarantine s.7z
$ xattr s.7z
