This helped me a lot whenever I'm in a remote server trying to find a keyword or specific text amongst a bunch of files.

This command will save you a lot of time:

grep -rwn [path] -e 'pattern'

• r stands for recursion
• n displays the line number
• w matches the whole word

Refer to man find pages for more info.

Wanted to view the size of a file in terminal but don't understand the number of bytes displayed? No worries, just type this command and it'll display the size of the in human-readable format:

du -sh filename.ext

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/

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.

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

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!

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!
