Exit from bash script but keep the process running

I'm running a server and needs to execute following command with the parameters. The scripts works great at the moment but the problem is when I run the script I cannot return back to the console. It keeps running in the console. If I stop it forcefully then the the process also going to stop.

I want to keep running the process and return to the console. 

#!/bin/sh
php /home/stjc/app/artisan queue:listen --timeout=60 --tries=5

Thanks

One more option is there to send process in background as explained below:

Run script OR command you wish to run: For example

girishp@~$ ping 10.137.108.192
PING 10.137.108.192 (10.137.108.192) 56(84) bytes of data.
64 bytes from 10.137.108.192: icmp_seq=1 ttl=64 time=7.18 ms
64 bytes from 10.137.108.192: icmp_seq=2 ttl=64 time=0.367 ms

Press Ctrl+Z while command is running, It will stop running

^Z
[1]+  Stopped                 ping 10.137.108.192

type bg in terminal to resume execution in background

 girishp@~$ bg
 [1]+ ping 10.137.108.192 &
 girishp@~$ 64 bytes from 10.137.108.192: icmp_seq=5 ttl=64 time=5.46 ms
 64 bytes from 10.137.108.192: icmp_seq=6 ttl=64 time=4.56 ms

You can again run it in foreground by typing fg in terminal:

girishp@~$fg
ping 10.137.108.192
64 bytes from 10.137.108.192: icmp_seq=22 ttl=64 time=0.397 ms
64 bytes from 10.137.108.192: icmp_seq=23 ttl=64 time=3.99 ms

You can use an & at the end of your command to run a process in the background, or the nohup command to disconnect a process from your terminal entirely so that it continues running even after you exit the shell.

The error : command not found is a separate problem. The text before the : is a command that the environment couldn't find. Since there's nothing before the : you're trying to start a command consisting of the empty string; here's an example:

$ foo
-bash: foo: command not found
$ ''
-bash: : command not found

Likely this is because you have a miss-set variable that you're using as a command, and therefore something is trying to to execute the empty-string command (which, of course, doesn't exist).

Run that process in background:

#!/bin/sh
(php /home/stjc/app/artisan queue:listen --timeout=60 --tries=5) &

try adding an ampersand(&) at the end with brackets on either side of original command.

Edit:

: is a shell builtin which means NOP depending on your OS it might a problem try escaping the it in the php command and see if it works for you

#!/bin/sh
(php /home/stjc/app/artisan queue\:listen --timeout=60 --tries=5) &

also puting the full path to your php interpreter is strongly advised.

Just append & after your command and the shell will run the job in the backend.It will returns something like:[1] 3633.[1] means shell job id, and 3633 means OS process id. If you want to stop the task, just simply type kill 3633. 

#!/bin/sh
php /home/stjc/app/artisan queue:listen --timeout=60 --tries=5 &
