Laravel - Linux(ubuntu) 实时处理并在网页上显示输出（刀片）

Question

I want to get the real-time output of a running process on my server. For the script I made something simple in bash:

Script 1 (script.sh).

#!/bin/bash

y=0;

while [ $y > 0 ]; do
y=$((y+1))
sleep 1;
echo $y
echo "I am baking pies. I have $y so far."
done

Script 2 (test.sh).

#!/bin/bash

~/script.sh > /dev/null &
pid=$!

echo $pid
strace -e trace=write -s1000 -fp $pid 2>&1 \
| grep --line-buffered -o '".\+[^"]"' \
| grep --line-buffered -o '[^"]\+[^"]' \
| while read -r line; do
printf "%b " $line;
done

The second script's role is to run the first one, get it's pid and than trace the output of that pid. On the server side this should be enough but I may be wrong. However, on the laravel side I couldn't figure a way to get the live output of that script.

Laravel, using Symfony (using the Symfony Docs example: https://symfony.com/doc/current/components/process.html ).

$process = new Process(['/test.sh']);
$process->run();

// executes after the command finishes
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);
}

echo $process->getOutput();

The script works almost like it should be, but there is a problem:

When the script runs laravel only prints the pid and doesn't wait for the output of the strace command. Now, is there a way to get the live output of the script while it is running? If it is not possible using Laravel and Symfony alone could I achieve it by using VueJS (which I am familiarized with and practiced in the past few months)?

Answer 1

yes u can do like that

for example i created one script test.sh and store in laravel root project ..

a=0

while [ $a -lt 10 ]
do
   echo $a
   sleep 1
   a=`expr $a + 1`
done

if you are ubuntu user then give a permission to execute a script file permision like that

sudo chmod +x test.sh

now in laravel create new console command

php artisan make:command test

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Symfony\Component\Process\Process;

class test extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'test';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'test description';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $process = new Process([base_path('test.sh')]);
        $process->start();

        foreach ($process as $type => $data) {
            if ($process::OUT === $type) {
                info($data);    //output store in log file..
                $this->info($data);  //show output in console..
                //       $this->info(print_r($data,true)) // if output is array or object then used
            } else {
                $this->warn("error :- ".$data);
            }
        }

        $this->info("get output");
    }
}
