Linux File Permissions Made Easy 🛡️🐧Hey there! Ready to dive into the world of Linux file permissions? Let’s break it down simply so you can master controlling access to your files.What Are File Permissions? 🔐File permissions determine who can read, write, or execute your files. Think of it like setting rules for who can view, edit, or run your programs.Symbolic Representation 📝Permissions are displayed as a 10-character string:First character: file type (- for files, d for directories).Next nine characters: permissions for the owner, group, and others.Example: -rwxr-xr--rwx: Owner can read, write, and execute.r-x: Group can read and execute.r--: Others can read.Octal Representation 🔢Permissions can also be represented numerically using octal (base-8) notation. Each set of permissions is converted to a single digit:r (read) = 4w (write) = 2x (execute) = 1Example: -rwxr-xr-- translates to 754 (7 for rwx, 5 for r-x, 4 for r--).Changing Permissions 🔄To change permissions, use the chmod command:chmod u+rwx,g+rx,o+r filename u is the owner, g is the group, o is others.+ adds permission, - removes it.chmod 754 filename Viewing Permissions 👀Use the ls -l command to view file permissions:ls -l filename Common Permission Sets 📋777 (rwxrwxrwx): Full access for everyone.755 (rwxr-xr-x): Owner can read/write/execute; others can read/execute.644 (rw-r--r--): Owner can read/write; others can read.Mastering these basics will help you control access and ensure security on your Linux system. Happy managing! 🚀🔒 #Linux #SysAdmin #TechTips #Devops
