Welcome to the Shell Kingdom, where the power of the Bash terminal awaits you! Prepare to unlock the secrets of commands, file manipulation, and permissions in a world of endless possibilities. 🌌✨
Before you set off on your journey through the kingdom, let's first get familiar withBash, the language that governs the land. The Bash shell is where all commands are issued, and it's your magical interface to the Shell Kingdom.
To enter the kingdom (open the terminal), you'll simply open your Bash shell. You'll be greeted with a prompt—usually something like:
user@computer:~$
Here, you can type your commands and see immediate results. 🌳
Commands in Bash are like magical incantations that make the kingdom come alive. 🏰
pwd # Prints the current directory (Where you are!)
ls # Lists files in your current directory
cd [path] # Changes to a new directory
mkdir [name] # Creates a new directory
rm [name] # Removes a file or directory
mkdir forest_trail # Creates a directory named forest_trail
cd forest_trail # Moves into the forest_trail
To build a new castle (folder) in your domain, you'll use the mkdir command:
mkdir folder_name
Example:
mkdir treasure_chamber # Creates a directory named treasure_chamber
Now, your treasure is safely locked away in the treasure_chamber!
Folders (directories) are like castles in the Shell Kingdom, housing all your treasures and secrets. Knowing how to build, move, and organize them is key to ruling your domain. 🏰
cd folder_name # Move into a folder
cd .. # Move back to the parent folder
cd /path/to/folder # Move to an absolute path
mv old_folder_name new_folder_name
cp -r folder_name new_folder_name
Example:
cp -r treasure_chamber backup_chamber
rm -r folder_name
Add the " -f " option for forced deletion:
rm -rf folder_name
Bash opens the gates to effortless file interaction, empowering you to create, explore, and command your digital world with a few keystrokes. Whether uncovering hidden treasures or organizing chaos, Bash makes the impossible feel magical! ✨
cat file_name.txt
echo "New Entry" >> file_name.txt
echo "New Entry" > file_name.txt
In the Shell Kingdom, not everyone should have access to your treasures. The chmod command is your magical shield, controlling who can read, write, or execute files.
Use chmod to control access. You can give specific powers (permissions) to different users.
chmod 755 folder_name
Example:
chmod 755 treasure_chamber
The numbers represent different levels of access:
You can also use symbolic notation:
chmod u+x file_name

Let's put your newfound knowledge to the test! 🏰🌲
🏆 Congratulations, adventurer! 🏆 You've successfully navigated the realms of Bash, learned to manage folders, and even wielded the mighty chmod command to protect your treasures. With these skills, you can now rule your Shell Kingdom with wisdom and power.
