Trying to make a script to run 3 other scripts in a screen.
Hello, my name is Spurkle. I'm new to linux stuff.

Currently I am trying to make a script which will run three other scripts in screen.

This is the code:
Code:
sudo screen -S hubServ /var/servers/hub/hub.sh
sudo screen -S facServh /var/servers/factions/factions.sh
sudo screen -S bunServ /var/servers/bungeecord/bungeecord.sh

And this is what these scripts contain:
Code:
java -Xmx768M -Xms768M -jar bukkit.jar nogui


But when i try to run the launch.sh script (The one which should start 3 other scripts) i get this:

Code:
Cannot exec '/var/servers/factions/factions.sh': Permission denied
Cannot exec '/var/servers/hub/hub.sh': Permission denied
Cannot exec '/var/servers/bungeecord/bungeecord.sh': Permission denied

I tried giving all the files chmod 777, but it does not seem to work.


Any help would be appreciated.

Best regards,
Spurkle.

Strange if you can run the scripts interactively without a problem. Still you need to make sure the entire directory path is executeable as well.

Please run
Code:
ls -ld /var/servers
ls -ld /var/servers/hub
ls -ld /var/servers/hub/hub.sh

Permissions should be 755 (not 777 that is unsafe)

This is what i got:
Code:
root@CrimeCentral:~# ls -ld /var/servers
drwxrwxrwx 5 ftpadmin root 4096 Dec 18 13:24 /var/servers


root@CrimeCentral:~# ls -ld /var/servers/hub
drwxrwxrwx 9 ftpadmin root 4096 Dec 21 07:50 /var/servers/hub


root@CrimeCentral:~# ls -ld /var/servers/hub/hub.sh
-rwxrwxrwx 1 ftpadmin ftpadmin 45 Dec 21 07:50 /var/servers/hub/hub.sh

I think the problem is here:

You see, running a command through "sudo" means it is not executed as your user but as some other user. Which one that is (most times it is "root", but that doesn't have to be so) can be found out only by inspecting the file /etc/sudoers. Have a look at it with "view", "more" or something similar (it is safe to view it but under no circumstances change it!).

As the scripts are executable for everybody already you might consider dumping the "sudo" altogether and just run

Code:
screen -S hubServ /var/servers/hub/hub.sh
screen -S facServh /var/servers/factions/factions.sh
screen -S bunServ /var/servers/bungeecord/bungeecord.sh

instead.

I hope this helps.
