Question

I am trying to start program in background from command line:

[root@my]# php file.php&
[1] 16897
[root@my]# bg
[1]+  Stopped file.php

It always stopped doesn’t matter which php to start, where the problem is?

Answer 1

Try with nohup

nohup php -r 'while (true) { echo "a";}' &

works fine for me (on kubuntu).

Note : standard output :

the standard output is redirected to nohup.out (if it has not already been redirected); nohup.out is located in the folder from where you run the command in command line .

So be carful to handle output properly, otherwise you might end up with a very big file after a couple of days/months

Note 2 : to stop the process :

The final & which backgrounds the process will print the PID. To kill the nohup process, run :

kill {PID}

(with {PID} being the PID printed after you executed the ” nohup php -r 'while (true) { echo "a";}' & ” command).

You could alternatively use kill -9 {PID} if you need to force kill.
