How come cd doesn't work in my shell script?

• SOLVED I'm trying to make a shell script on my Linux Amazon-EC2 server that will start my Minecraft server but the cd command says it can't find the directory or file when I try to change to the directory the server executable is in. Please note I have next to no experience with shell script of any kind. Does it have to with permissions in the folder this file is located in or the file itself? The file is named "startServer". #!/bin/bash cd /home/ec2-user/Minecraft java -Xmx2048M -Xms2048M -jar minecraft_server.jar nogui *I did not save it with a file extension. Should I? Does it need to be?

• Answer:

  In order to make a script runnable you need to modify the permissions on the script so that it is executable. The command to change permissions on Linux or UNIX is http://en.wikipedia.org/wiki/Chmod chmod +x ./name_of_your_script Will grant the current user permission to execute the script. The #! at the start of your script indicates to the interactive shell that the script is to be interpreted by /bin/bash so you do not really need add an extention to the file name. However, it is a common convention to append .sh to shell scripts.
