This can be solved by blaming on a file in the repo (since the file would have the same line breaks)

git blame HEAD file.txt

SELinux (read as S.E.Linux)

The main purpose of using SELinux is to protect the system from “unpredictable” security breaches.
It provides a kernel-level security protection based on a white-list policy and can protect from things like application bugs and application misconfigurations.
(Buggy/misconfigured FTP/HTTP/other daemons may give the users more privileges than they should)

When troubleshooting SELinux related permission issues, “ls -Z” is the command to view the “label”, which defines the access privileges.
