Frequently Asked Questions (FAQ)
Q. What is the difference between 644 and 755?
A. 644 is the standard permission for files, allowing the owner to read and write while others can only read. 755 is the standard permission for directories and executables, giving the owner full permissions while others can read and execute.
Q. Is 777 safe?
A. 777 grants full permissions to all users, which poses a security risk. It is generally not recommended but may be used for temporary directories in development environments.
