This tool calculates the SHA256 checksum of a file and writes that and the mtime to extended attributes (xattrs). Subsequent runs validate if the mtime hasn’t changed, or update if it has.

I added it to my default install list of homebrew tools on OSX.
repl.it is a browser-based IDE, sort of like jsfiddle, but for many languages. It’s free and super cool.

reason) but it seems to get the job done. One less thing to have poking out

container VM and I can use the PGP smartcard features of the Yubikey 4 on
