Issue Description

I am trying to extract commit messages from last 50 commits for further processing. On my local machine I can print all last 50 commit messages. But to my surprise on GitHub Action it prints only 1 ending with \n.

Command executed

puts %x{git log -50 --pretty=oneline --abbrev-commit}.inspect

Complete output when running fastlane, including the stack trace and command used

"logging commits for further processing\n"
