Creating a shell script to run Java program

Question

I used a shell script to run a Java class. My script contains

#!/bin/sh
java -jar jobs/job.jar

These are my failed attempts to run it.

[root@]#sh testapp.sh
Unable to access jarfile jobs/job.jar

if I just do this at the command line it works fine

[root@]#java -jar jobs/job.jar

thanks.

• Cedric H.: Do you run the script from the same directory ?
• emory: It is not recommended to routinely run things in super user mode (aka root).

Answer 1

The best way is to get the current dirname and get in there with this:

#!/bin/sh
cd `dirname "0ドル"`
java -jar ./job/job.jar

• Sloy: This seems like the actual right answer, because using an absolute path is not an option when you plan to move the files (or even share it)

Answer 2

Use the absolute path to your JAR file, e. g. /root/jobs/job.jar.
