In fact, there's already an archiver named ARC from the BBS days:

Not only that, there's a historical program called Arc that is also a file archiver/compressor. It led to PKZIP.

Come to think of it, a variant of it is still packaged in Debian, package is called "arc".

Incidentally, for anyone choosing a name, the namecheck program from the Debian devscripts package is handy for checking if a particular name is already in use. Not perfect, but handy anyway.

I think it's a great name.

The author probably has this as a binary living in his PATH so they can just type

    $ arc <args>

It might be obvious, but who wants a long or strange name when you're using a command line utility often.

When the name conflicts with another command line utility?

Phabricator's command-line tool "Arcanist" is called arc:

I used the arc archiver mentioned by others, back in the 90's if not earlier. I've probably still got archives on a disk somewhere.

And don't forget Arq.

Sort of agree, but the title made me think of https://www.arqbackup.com

Quite close field to be honest.
