Do nothing, returning a non-zero (false) exit status
Syntax
false
'false' does nothing except return an exit status of 1, meaning "failure". It can be used as a place holder in shell scripts where an
unsuccessful command is needed.
'false' ignores all command line arguments, since to do otherwise would change expected behavior that some programmers might be relying on.
This is a BASH shell builtin, to display your local syntax from the bash prompt type: help false
“False in one thing, false in everything” ~ Legal maxim
Local man page: false - Command line help page on your local machine.
true - Do nothing, successfully.
yes - Print a string until interrupted.
