I have followed steps and installed package and below command is showing errors

php phpcs.phar --standard=PSR2 --encoding=utf-8 -n -p /path/to/file.php

but why I tried, I have used git bash to commit in winows

git commit -m "" file.php

it does not show error message and stopped committing code

When I run the pre-commits on my windows machine it always fails

When I run the exact same phpcs command in my docker container, the -p flag shows the progress (100%), hence the return value of this command in the bash script does not return 0, so it is interpreted as an error

When I remove the -p the command returns empty, which is good, however the if statement seems not be correct
When I replace the if comparison if 'ne' then it works.
The code below the pre-commit succeeds on a valid phpcs check, and fails on an invalid phpcs check.

    ./vendor/bin/phpcs --standard=PSR2 --exclude=Generic.Files.LineLength --extensions=php -n $FILES
    if [ $? ne 0 ]

Is it possible to ad a new branch or setup script to make it work out of the box (w/o forking) with OpenMage/magento-lts#982? Magento1/Openmage just needs two sniffs to be excluded by default .... (
--exclude=Squiz.Classes.ValidClassName,PSR1.Classes.ClassDeclaration)

Either a new branch (openmage-lts) with a modified hook, or add a new setup-script and a new hook? (pre-commit.default, pre-commit.openmage-lts) ... or close it :)
