@syzygy GNU coreutils is only one GNU package out of 388; https://gnu.org/software

GNU coreutils does make some memory/speed tradeoffs, but all of them run great just as long as your computer has 512MiB of RAM (oh wait, you have 8 or 16 or 32 times that).

`/bin/true` will always return zero.

But unlike inferior true implementations, true will assist the user in working out what the license is as well as how to use the software, in the users native language.
Behold;
`/bin/true --version`
true (GNU coreutils) 9.5

As that prints stuff to stdout, obviously that can fail, but in a script, are you going to write `/bin/true` or `/bin/true --help` to get a zero exit status .... drumroll ... you'll only ever use the former, or use GNU bash's built-in for true, which is guaranteed to return zero.
