Linux Command T-Shirts

Description: Setting 777 permissions to a file or directory means that it will be readable, writable and executable by all users and may pose a huge security risk. For example, if you recursively change the permissions of all files and subdirectories under the /var/www directory to 777, any user on the system will be able to create, delete or modify files in that directory. If you experience permission issues with your web server, instead of recursively setting the permission to 777, change the file’s ownership to the user running the application and set the file’s permissions to 644 and directory’s permissions to 755. File ownership can be changed using the chown command and permissions with the chmod command.
