Re: [Sshpass-devel] Option for reading from arbitrary environment variable

[Chris B. <chr...@gm...>]

My initial use case was rsync proxyjumping through another server, both of
which need passwords (in my case, the gateway disallows key logins and
doesn't pass keys over to the next server). It was convenient to load the
password(s) from a .env file rather than typing them myself and having them
in the shell history.
