Master Linux File Ownership and Permissions with chown and chmod
This article explains how the Linux commands chown and chmod control file ownership and access modes, using a simple cartoon analogy to illustrate how changing owners and setting permission bits like 777 affect who can open the "door" to a file.
chown is a Linux command used to change the owner of a file or directory, illustrated in the cartoon as handing the "key" of a resource (the door) to another person.
chmod is a Linux command that modifies a file's access mode; for example, chmod 777 opens the "door" completely, allowing anyone to read, write, or execute the file.
By combining the cartoon explanation, you should now fully understand what chown and chmod do and how they differ.
