lterm: Online bash terminal(emulator) tutorial

Check out the site live at:

lterm is an online Terminal Emulator. It is a step by step tutorial that will teach you the bash commands by making you execute them.

Nothing is better than learning by doing.

It is fully online and doesn't require any extra shitty access. Being an emulator, it only virtualizes a terminal environment and so the commands executed doesn't effect either the server or your local machine.

List of commands available presently

Command	Does...
echo	To display a string
pwd	Shows you the present working directory
ls	Lists all the files
cd	To change directory - change the current working directory to a specific directory
cd ..	Moves you up one directory(parent)
cat	Concatenate and print the content of files
clear	Clears the terminal screen
touch	Changes file timestamps or creates a new file
cp/mv	To copy/move files
rm	Delets a file/directory
uname	Shows the name of the Linux/Unix system you are using

To add your new commands

• edit the file main.js to add your commands.
• You don't have to worry about any other files or programs.

---

• If a command doesn't need further steps:

// without argument
ls: function() {
        this.echo('This is the ls command\n');
}

// with argument
echo: function(arg1) {
        this.echo('This is the echo command' + arg1 + '\n');
}

• If a command needs further steps:

cd: function(arg1) {
	this.push(function(cmd, term) {
                if(cmd == 'another_command')
                    this.echo('another_command');
		}, {
                    prompt: '[[b;#44D544;]lterm@localhost/' + arg1 + ':~$] ',
                   }
        );
}

---

IMPORTANT

• On addition of a new command, increase the size of arr array. This array acts like a counter to check if a task/command is completed or not.
• You need to add the new command into the second array arr2 . This array stores all the commands and helps in fetching the completed commands when the history command is executed.
• Please make sure that you do not alter the positions of commands in arr2, You need to add the new command towards the last.
• Example: If I add the command - echo. I will add another 0 to the end of arr. Then I will make arr[index] = 1 under echo command.

var arr = [0,0,0,0,0,0,0,0,0,0,0,0,0,0]; // Will add another 0 here. The place where you added is the index.
var arr2 = ['list of all other commands']; // Will add the 'echo' command here
...
...
echo: function(arg1) {
            arr[index_where_you_added_0] = 1;	// Will make the value at that index to 1. 	
            this.echo(arg1 + '\n');
            this.echo('> The [[b;#ff3300;]echo] command prints back your arguments.');
            this.echo('> Type [[b;#ff3300;]help] and check your first task is completed.');
            this.echo('> Now type [[b;#ff3300;]pwd] to continue.');
},

• If you face any problem or cannot understand anything, open up an issue.
• You can also edit the readme and make it more user friendly to help out new contributors.

NOTE: Kindly keep the display of the terminal intact while making an update. A single extra space can make the look of the emulator little odd. So keep that in mind while printing something using echo command.

Note: Kindly have interpretable & good commit messages. Don't assume me to be some Jedi with powers to be able to make out every commit with a single word as message. May the Force be with you.
