What command is used to change the current directory in Linux?

The command used to change the current directory in Linux is "cd," which stands for "change directory." When you want to navigate the filesystem from the command line, you use this command followed by the path of the directory you wish to enter. For example, typing "cd /home/user" will change the current directory to "/home/user".

Using "cd" allows users to traverse directories easily, providing a straightforward method for accessing files and other directories. This command is fundamental in interactive shell sessions, where users need to manipulate their current working directory frequently.

While other commands like "set," "move," and "chdir" may relate to directory manipulation in different contexts or operating systems, "cd" is the standard command in Linux for changing directories. "chdir" is actually a system call in POSIX-compliant systems, while "set" and "move" do not serve the purpose of changing directories in this context.
