change Jenkins shell for only one pipeline

How can I make Jenkins use Bash rather than its native shell for just one Jenkins pipeline/Jenkinsfile? Does the "agent" help me to do this?

I wrote a shell script for deployment but some of the parameters contain whitespace which messes up the resulting command I generate by losing some args. I've found how to avoid this problem by globally configuring Jenkins shell type to be Bash. But when I change the global shell type, my other Jenkins pipelines that use the Jenkins docker plugin syntax get broken when they use the 'sh' command within a docker container. My workaround is to ping pong the global setting for shell type depending on which Jenkins build I want to run. Its a royal PITA.

I'm embarrassed to say all I needed was a shebang.

My Jenkinsfile runs a custom (bash) shell script, using Jenkin's sh command, like in the following:

sh "./deploy.sh \"arg1\" \"arg 2\" \"arg3\""

In order to force deploy.sh to run within Bash, the contents of deploy.sh need to include #!/bin/bash on the first line, as in:

#!/bin/bash
echo "deploy args: $@"

Regardless, I think there should be a way to tell a Jenkins pipeline that it should run with specific settings, like sh=bash.
