Updated example results. And all looks good to me

[L1so]

Referring to danipragustia@27d36af

is_openbsd() {
if [ $(uname) = "OpenBSD" ]; then
    return 0;
fi
return 1;
}

Shouldn't this be.

is_openbsd() {
if [ $(uname) = "OpenBSD" ]; then
    return 0;
else
    return 1;
fi
}

Because otherwise the return value is going to be overwritten by that non-zero value, this break the following if clause..

Just revisited this issues, your codes should be fine. Though I recommend to shorten it.

is_openbsd() {
  [ "$(uname)" = "OpenBSD" ] && return 0 || return 1
}

Does the same thing and less line.

All set!

Thanks for taking the time to create a PR, I really appreciate it. I'll be sure to merge it 😃

Never used *BSD before, so I don't know the environment there— your PR really helps the development of this script.

Again, thanks (Makasih ya gan he he 👍 )

This is just a trivial fix, nothing special.
