SYNOPSIS

false

DESCRIPTION

unix false is non-zero. The unix false command returns 1. In Boolean Logic zero is usually considered false. Unix false ought to be called "fail" or something. false is a Bash builtin, so the discrete command is actually rarely run.

cLIeNUX false is about as fast as you can write a C program. Here's how the command compares to the built-in....

		:; cLIeNUX /dev/tty2  13:53:38   /command
		:;time /.bi/false

		real    0m0.037s
		user    0m0.000s
		sys     0m0.020s
		:; cLIeNUX /dev/tty2  13:53:45   /command
		:;time false

		real    0m0.001s
		user    0m0.010s
		sys     0m0.000s
		:; cLIeNUX /dev/tty2  13:53:52   /command
		:;

The builtin is 37 times faster than a command that does almost nothing.
