What are common Linux directory management commands?

Common Linux Directory Management Commands

Linux provides a variety of commands for managing directories and navigating the file system. Here are some of the most common and useful directory management commands:

cd (Change Directory)

The cd command is used to change the current working directory. For example, to change to the /home/user directory, you would use the command:

cd /home/user

You can also use relative paths to navigate the file system. For example, if you are currently in the /home/user directory and want to change to the documents subdirectory, you can use:

cd documents

ls (List Directory Contents)

The ls command is used to list the contents of a directory. By default, it will list the files and subdirectories in the current working directory. You can also use it to list the contents of a specific directory, like this:

ls /home/user/documents

The ls command has several useful options, such as:

• ls -l: Displays detailed information about each file and directory, including permissions, owner, size, and modification date.
• ls -a: Displays all files, including hidden files (those starting with a dot).
• ls -R: Recursively lists the contents of all subdirectories.

mkdir (Make Directory)

The mkdir command is used to create a new directory. For example, to create a new directory called "projects" in the current working directory, you would use:

mkdir projects

You can also create directories in a specific location by providing the full path:

mkdir /home/user/projects

rmdir (Remove Directory)

The rmdir command is used to delete an empty directory. For example, to remove the "projects" directory from the current working directory, you would use:

rmdir projects

Note that rmdir will only remove empty directories. If the directory contains files or subdirectories, you'll need to use the rm -r command instead.

rm -r (Remove Directory Recursively)

The rm -r command is used to delete a directory and all its contents (files and subdirectories) recursively. For example, to remove the "projects" directory and all its contents, you would use:

rm -r projects

Be careful when using rm -r, as it can permanently delete important data if used incorrectly.

pwd (Print Working Directory)

The pwd command is used to display the current working directory. This can be useful when you're not sure where you are in the file system. For example:

pwd
/home/user/documents

This shows that the current working directory is /home/user/documents.
