I need to execute a groovy script file from bash, and I need the script to have a working directory of the directory it exists in.
That is, in my bash script, I'm doing this:
/opt/script/myscript.groovy &
But this seems to set the working directory to /etc/init.d, the directory I'm calling from. How do I change the working directory for that script to /opt/script?

Using the pushd Command In the above script, we've used pushd and popd commands to switch between the directories. As we know, pushd saves the current directory and switches to the new directory given as an argument. And later, we can use popd to restore the pushed directory.
The shell always identifies a particular directory within which you are assumed to be working. This directory is known as the working directory (also known as the current working directory). To work with a file within your working directory, you need specify only the file name with a command.
To change directories, use the command cd followed by the name of the directory (e.g. cd downloads ). Then, you can print your current working directory again to check the new path.
If you are using start-stop-daemon inside your /etc/init.d script, you can take advantage of the -d parameter for achieving this:
-d, --chdir path
Chdir to path before starting the process. This is done after the chroot if the -r|--chroot option is set. When not specified, start-stop-daemon will chdir to the root directory before starting the process.
/etc/init.d
probably you are runnig (starting) that script from /etc/init.d?
Add cd /opt/script at the first line of the script
OR
...to keep it dynamic, add:
cd "$(dirname "$0")"
