I guess there is not too much one can say about the bash built-ins `true' and `false'. Nonetheless, I suggest that the info pages should list these built-ins individually like other built-ins. Currently, the only hint on their existence is buried in the info node on Shell Builtin Commands saying that
The `:', `true', `false', and `test' builtins do not accept options and do not treat `--' specially. Or am I missing something? (I don't know whether these commands should be listed in the info node on Bourne Shell Builtins or under Bash Builtins.) I am using GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu). Also, I have Edition 4.2, last updated 28 December 2010, of `The GNU Bash Reference Manual', for `Bash', Version 4.2. Roland
