Zip a file

This comes in handy especially whenever you want to download multiples files from a server or take backups.

zip [option] output_file input1 input2

For example: if you want to zip an entire directory with it's file contents, just do this:

zip -r myfiles.zip folder/

Insert mode

I get it, a lot of people are confused on how to start typing on VIM. All you have to do is press the A key, the editor will be switched to insert mode.

Press ESC key to switch back to normal mode.

Check RAM and disk space

RAM space

Type the following command to view available memory in your system:

free -h

Disk space

Type the following command to view available disk space in your system:

df -h

Symbolic storage link in shared hosting

If you're hosting a laravel project via cPanel, chances are that it could be a shared hosting server and that means you can't really use php artisan storage:link for this. But don't worry, there's another way to this. Just follow the steps below:

1. Create a symlink

In your public_html/public directory, remove the storage folder. Next, create a symlink.php file in your public_html directory and add the following code:

<?php
$targetFolder = $_SERVER['DOCUMENT_ROOT'].'/storage/app/public';
$linkedFolder = $_SERVER['DOCUMENT_ROOT'].'/public/storage';
symlink($targetFolder, $linkedFolder);
echo "done";
?>

2. Create a custom route to access storage

Alright, this is kind of a hack but it works extremely fine. Just add the following route in your routes/web.php file:

<?php
Route::get('/storage/anyfolder/{filename}', function($filename){
    // Your folder path
    $folder_path = storage_path('app/public/anyfolder/'.$filename);

    // check if the file exists
    if(!File::exists($folder_path)) {
        abort(404);
    }

    $file = File::get($folder_path);
    $type = File::mimeType($folder_path);

    $response = Response::make($file, 200);
    $response->header("Content-Type", $type);

    return $response;
})
?>

Now, you can access your images or any other assets easily using:

<?php
asset('storage/anyfolder/'.$filename)
?>

Hope this helps you out!

Integrate Excel into your Laravel project

Before you integrate Excel into your application, make sure your project meets the following requirements:

  • PHP v7.0 or greater
  • Laravel v5.5 or greater
  • PhpSpreadsheet v1.6 or greater

Download the package

Download the maatwebsite/excel package using Composer:

composer require maatwebsite/excel

Add it to service provider

By default, this will be done automatically when you're installing the package but if you want to do it yourself, add this in your config/app.php file:

<?php
// ...
'providers' => [
    // ...
    Maatwebsite\Excel\ExcelServiceProvider::class,
],

// ...
'aliases' => [
    // ...
    'Excel' => 'Maatwebsite\Excel\Facades\Excel::class',
],
?>;

Publish your configuration

Last but not the least, run the vendor:publish command using artisan to publish your configuration:

php artisan vendor:publish -provider="Maatwebsite\Excel\ExcelServiceProvider"

Upon publishing, the config/excel.php configuration file will be created where you can make your changes.

Hope this helps you out!

View battery status

This comes in handy if you're using the terminal in full screen but still want to know your battery life. Just type the following:

upower -i /org/freedesktop/UPower/devices/battery_BAT0

Set up a new repository

Are you new to using Git? Then this is for you.

1. Set up a Git account

Go to GitHub and create your account with your email address.

2. Create a repository

Just create a new project with whatever you wanted. For this, you can just create git-starter-repo or something like that.

3. Initialize git in your project directory

Now, go to your project directory and initialize git by doing the following:

git init

4. Add your files

Add your files to the repository by doing the following:

git add .

Or if you want add selected files:

git add file_1 file_2

5. Commit your changes

Before you push your changes, you need to write a message about what changes are done:

git commit -m "this is my first commit"

6. Link your project to the repo

Do the following to link your project to the repo that you've created in step 1:

git remote add origin https://github.com/youraccount/repositoryname.git

7. Push changes

You can decide which branch you wanted to push but initially, you'll have one branch, which is called master:

git push -u origin master

Or if you have an existing branch, just replace master with yourbranchname.

Hope that helps you out!

Checkout branch

Want to create a new branch in your project? Simple, just do this:

git checkout -b new_branch

By doing this, you'll automatically be shifted to a new branch of your project. To check which branch you're working on, type this:

git branch

And you should be able to see your current branch marked with a *:

master
* new_branch
