Admittedly I still use cat for this.

This also works too, but it's more verbose:

echo "$(<foo.txt)"

It's mentioned in the Bash man pages:

The command substitution $(cat file) can be replaced by the equivalent but faster $(< file).

EDIT: I was just informed that simply <foo.txt works too.

how in the world is this not a useless use of echo and equivalent to <foo.txt

OK, TIL you can just do <foo.txt. I didn't think that worked. Thanks!
