为什么命令行说在后台运行后进程停止了？

I have a script that takes 10 minutes to run:

我有一个需要10分钟才能运行的脚本:

php /path/to/script.php

If I run it as above it prints out feedback along the way like so:

如果我按上面的方式运行它会像这样打印出反馈:

> php /path/to/script.php
1    file_a.txt processed in 4.3 seconds
2    file_b.txt processed in 3.5 seconds
...

But I'd like to run several of these processes in parallel like so:

但我想像这样并行运行其中几个进程:

> php /path/to/script.php &>/dev/null &
> php /path/to/script.php &>/dev/null &

But every time I do this, I see that the previous one is stopped like this:

但每次我这样做,我都会看到前一个像这样停止:

> php /path/to/script.php &>/dev/null &
[1] 11206
> php /path/to/script.php &>/dev/null &
[1]+  Stopped                 php /path/to/script.php &>/dev/null

How can I run many of these scripts at once?

如何一次运行许多这些脚本?

So far I've tried:

到目前为止,我已经尝试过:

> php /path/to/script.php &
> php /path/to/script.php &/dev/null &
> nohup php /path/to/script.php &
nohup: ignoring input and appending output to `nohup.out'

I also have error_reporting(E_ALL) set and no errors show up when running manually.

我也设置了error_reporting(E_ALL),手动运行时不会显示任何错误。

UPDATE

Thanks to generous commenters, the following works:

#1

php /path/to/script.php < /dev/null

Or silence the script with:

或者用以下内容使脚本静音

php /path/to/script.php < /dev/null &>/dev/null &
