Question: 1 / 400

Which command can be used to change file permissions?

chmod

The command that can be used to change file permissions is "chmod." This command stands for "change mode" and is specifically designed to modify the access permissions of files and directories in a Linux system. When using chmod, you can set permissions for the file owner, the group, and others using either symbolic notation (like 'u' for user, 'g' for group, and 'o' for others) or octal notation (such as 755, which represents read, write, and execute permissions).

Other options do not serve this purpose. For example, "chown" is used to change the owner and group of a file rather than its permissions, while "chperm" and "setperm" are not standard Linux commands for modifying file access rights. Thus, "chmod" is the correct choice when it comes to altering file permissions in Linux.
