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.

git checkout -b feature/fooBar
)git commit -am 'Add some fooBar'
)git push origin feature/fooBar
)// 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');
}
cd: function(arg1) {
this.push(function(cmd, term) {
if(cmd == 'another_command')
this.echo('another_command');
}, {
prompt: '[[b;#44D544;]lterm@localhost/' + arg1 + ':~$] ',
}
);
}
IMPORTANT
arr
array. This array acts like a counter to check if a task/command is completed or not.arr2
. This array stores all the commands and helps in fetching the completed commands when the history command is executed.arr2
, You need to add the new command towards the last.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.');

- 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.*
