What is the primary purpose of the 'chmod' command in Linux?

To change the file owner.

To change file permissions.

The primary purpose of the 'chmod' command in Linux is to change file permissions. In Linux, file permissions determine who can read, write, or execute a file. The 'chmod' command modifies these permissions, allowing users to specify access levels for the owner of the file, the group associated with the file, and others. This is accomplished using symbolic (r, w, x) or numeric representation (e.g., 755, 644) to set permissions accordingly.

For example, if a user wants to allow others to execute a file while restricting write access for the owner, they can use 'chmod' to achieve that. These permissions are an integral part of the Linux security model, ensuring that files are accessed appropriately based on user roles and intentions.
