I’d say it gets a little different with command line utilities — maybe “utility” is the appropriate term here, but I’d call something like grep
a program, not an application (again — “utility” also works).
To be sure, grep
is extremely powerful, but its scope is limited.
It is really powerful per watt, and has a built-in UPS. Any homelab type things you could do with that? macOS+homebrew will give you a nice *NIX feel, very familiar if you’re a Linux user.
I’m a fan of having a remote homelab computer+disk for off-site storage. This would be a good candidate in that it wouldn’t use excessive power at a friend/family’s place, but may be overkill (I use a pi3 for that).
