Does anybody know what is “test” representing in this parameter
configuration?
my_unix_prompt> man test
gives:
Tests the expression given and sets the exit status to 0 if true,
and 1 if false. An expression is made up
of one or more operators and their arguments.
In other words “test” here is a unix command which evaluated the
expression supplied via the arguments.
Mostly used in its alternate form of “[ … ]” in shell scripts
