if tests the exit status of [. In the "if" branch, by definition, $? will be 0. It is the exit code of the command [ -s temp.txt ]. Yes, it is confusing to newbies that "open square bracket" is the name of a command, but that's what it is. You can call it test if you think that's less confusing.

Code:
test -s file66.txt || { echo "It's zero"; exit 99; }

dist::zilla::app::command::test

Dist::Zilla::App::Command::test(3pm)			User Contributed Perl Documentation		      Dist::Zilla::App::Command::test(3pm)

NAME

       Dist::Zilla::App::Command::test - test your dist

VERSION

       version 4.300020

SYNOPSIS

	 dzil test [ --release ] [ --no-author ] [ --automated ] [ --all ]

DESCRIPTION

       This command is a thin wrapper around the test method in Dist::Zilla.  It builds your dist and runs the tests with the AUTHOR_TESTING
       environment variable turned on, so it's like doing this:

	 export AUTHOR_TESTING=1
	 dzil build --no-tgz
	 cd $BUILD_DIRECTORY
	 perl Makefile.PL
	 make
	 make test

       A build that fails tests will be left behind for analysis, and dzil will exit a non-zero value.	If the tests are successful, the build
       directory will be removed and dzil will exit with status 0.

OPTIONS

   --release
       This will run the test suite with RELEASE_TESTING=1

   --automated
       This will run the test suite with AUTOMATED_TESTING=1

   --no-author
       This will run the test suite without setting AUTHOR_TESTING

   --all
       Equivalent to --release --automated --author
