[ $ARGS ]
is exactly equivalent to
test $ARGS
. The closing bracket is obligatory, as shown in test(1) (unless you
pass --help or --version). You get an error from bash instead of [
because [ is a bash builtin (equivalent to the "test" bash builtin), so
unless you run /usr/bin/[, bash will intercept the call to [ and try to
parse it itself.
