true/false: ignore options

[mknos]

• Standards document says that true does not handle options [1]
• No reference to options in the solaris manual either [2]
• I tested 4 versions of true and only the GNU version handles options
• test1: /bin/true --version # gnu version on linux
• test2: builtin true --version # bash builtin on linux
• test3: /usr/bin/true --version # openbsd version
• test4: builtin true --version # ksh builtin on openbsd
• The same is true for false

I once asked an internal to write me a login shell that would simply output a message saying that the account is restricted and then exit. He delivered three or four screens of code after a month of trying. I then showed him something like this:

printf( stdout, .... );
exit(1);
