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
