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.

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
