Which command changes the current working directory?

The command that changes the current working directory in a Linux environment is "cd," which stands for "change directory." When you use this command followed by the path to a directory, it allows you to navigate to that specified directory from your current location in the filesystem.

For instance, typing cd /home/user/Documents will take you directly to the Documents folder located within the home directory of the user. This functionality is fundamental in Linux navigation as it enables users to move between different directories easily.

While "chdir" is indeed a system call in some programming contexts with similar functionality to "cd," it is not a command that users typically enter into a shell. "move" is not a command used to navigate directories; it's often associated with moving files from one location to another. "directory" is not a recognized command in this context for changing the working directory. Thus, "cd" is the standard and correct command for this purpose.
