when trying to run a teamspeak server and a minecraft server on a newly rented VPS I ran into some big troubles. Whenever I try to run a shell script even when root it does not work.
One script: spigot.sh
#!/bin/sh
BINDIR=$(dirname "$(readlink -fn "$0")")
cd "$BINDIR"
java -Xms5G -Xmx7G -XX:MaxPermSize=128M -jar spigot.jar
Error after trying to use this as root
root#vps23946:/home/user/minecraft# ./spigot.sh
-bash: ./spigot.sh: Permission denied
Error after trying to use this as user
user#vps23946:~/minecraft$ ./spigot.sh
-bash: ./spigot.sh: Permission denied

With these I get the same errors.
I am running Ubuntu Server 14.04

Answer 1

Scripts and programs must be executable to be invoked by name. Either use chmod to add the executable permission to the file (chmod a+x ./spigot.sh) or invoke an executable interpreter and pass in the script, e.g. /bin/sh ./spigot.sh

Answer 2

Try
chmod +x spigot.sh
and that will enable the script to be executed
