Question

I was wondering if it is possible for an applescript application to run a shell script, then quit before the execution of the shell script is completed. This would be useful when running a server for a given amount of time. Instead of needing the applescript to be constantly running in the background, is there any way to run a function independently?

set server_name to text returned of (display dialog "Choose server." default answer "")
set success to do shell script "if [ -f \"/Users/jessefrohlich/Documents/Minecraft/" & server_name & "/minecraft_server.jar\" ]; then
    echo 1;
else
    echo 0;
fi"
if success is equal to "1" then
    do shell script "cd /Users/jessefrohlich/Documents/Minecraft/" & server_name & "
    java -Xmx1024M -Xms1024M -jar minecraft_server.jar"
else
    display dialog "Sorry, the file you chose is invalid."
end if

When the above is run as an application, it will launch the server properly. However, the application runScript.app will continue to run. The server will keep running even if the applescript is force quit. Is there any way to have it quit automatically, as soon as the server is launched?

Thanks

Try this. Good luck.

-- "> /dev/null" redirects standout out to nowhere land
--      - you can use some other file path if you want to capture its output
-- "2>&1" redirects standard error to the same place as standard out
--      - 2 stands for standard error
--      - 1 stands for standard out
--      - > is the redirect symbol
--      - & changes redirect's output from a file to a file descriptor (in this case standard out)
-- & the trailing & sends the process to the background

do shell script "cd /Users/jessefrohlich/Documents/Minecraft/" & server_name & " java -Xmx1024M -Xms1024M -jar minecraft_server.jar > /dev/null 2>&1 &"
