    ls -l # Detailed listing
    ls -a # Includes hidden files
    Copied!
    • cd: Changes the current directory.

    cd /path/to/directory
    cd ~ # Goes to the home directory
    Copied!
    • pwd: Prints the current working directory.

    pwd
    Copied!
    • mkdir: Creates a new directory.

    mkdir my_directory
    Copied!
    • rm: Removes files or directories.

    rm file.txt
    rm -r my_directory # Recursively removes a directory
    Copied!
    • cp: Copies files or directories.

    cp file.txt destination
    cp -r directory destination # Copies a directory
