what is /bin/true

Question

All,

In linux what is /bin/true

Thanks.....

Answer 1

From the man page:

true - do nothing, successfully

true returns a status 0.

Answer 2

/bin/true is a command that returns 0 (a truth value in the shell).

Its purpose is to use in places in a shell script where you would normally use a literal such as "true" in a programming language, but where the shell will only take a command to run.

/bin/false is the opposite that non-zero (a false value in the shell).
