Question: 1 / 400

What is the function of the 'chmod' command?

To change file ownership

To modify file permissions

The 'chmod' command is specifically designed to modify file permissions in a Linux or Unix-like operating system. File permissions determine who can read, write, or execute a file, enabling users to control access to their files. With 'chmod', users can set permissions for the owner of the file, the group associated with the file, and all other users, allowing for various configurations of access rights.

When using 'chmod', one can adjust permissions using either symbolic representation (e.g., adding "r" for read, "w" for write, and "x" for execute) or numeric representation (e.g., using octal numbers like 755). This versatility provides a powerful mechanism for maintaining security and ensuring that files are accessed appropriately according to the user's intent.

Understanding the role of 'chmod' is crucial for managing file security and accessibility in a Linux environment.
