But at least it does it successfully, which is more than we can say
for false.
The man page for "false" presents an interesting logic puzzle. The
intent of the false command is to "do nothing, unsuccessfully", which
I understand in natural language, but it must be a mess to a logician.
There is no success nor failure if nothing happens. If I don't play a
game, and instead do nothing, I have neither won nor lost that game.
So nothing can fit that interpretation of "do nothing,
unsuccessfully", regardless of what the documentation might claim.
It's pretty simple, actually:
false.c:
int main()
{
return 1;
}
true.c:
int main()
{
return 0;
}
The man pages were just being playful.
