escape variables in bamboo custom commands?

Question

This question is in reference to Atlassian Documentation: Bamboo variables

Does anyone know how to escape a variable on a custom command? For example, I want to use ${PWD##*/}, which will get me the working directory without the path. This works on the command line but not when parsed through the bamboo interpreter since it matches the format bamboo uses for variables.

I have confirmed that bamboo uses sh when executing scripts, though if you setup the script as a command it runs it via bash

sh does not allow for array processes. this is an odd limit to impose.

Can you confirm that Bamboo uses /bin/bash and NOT /bin/sh?

Hello Rob,

I have just test it using the following and the build ran successfully, mostly important, the file has been moved to the destination directory:

#!/bin/bash

echo ${PWD##*/}

/bin/mv "foo.txt" "/opt/atlassian/home/atlassian-bamboo-5.10.0/xml-data/builds/${PWD##*/}/download-data/build_logs/"

If you find this answer useful, I would kindly ask you to accept it so the same will be visible to others who might be facing the same issue you have inquired.

Thank you for your understanding.
