coreutils' src/true.c does exactly that - unless the user passes
an argument:
int
main (int argc, char **argv)
{
/* Recognize --help or --version only if it's the only command-line
argument. */
if (argc == 2)
{
...
}
return EXIT_STATUS;
}
So what's your point here? File size? Well, on my openSUSE system
/usr/bin/true needs 27328 bytes. Compared to the 6-7K your minimal
example above result in (compiled with -O2 -g, then stripped), I'd
consider this neglectable for nowadays' RAM and disk sizes.
Re. '/usr/bin/[' --help:
I'm using it myself from time to time, as I like the terse
information there.
Have a nice day,
