Why does `su` not work in Jenkins?

Question:

Tag: shell,jenkins,su

su doesn't seem to work as intended when run in Jenkins build job script.

su username1234
whoami 

returns jenkins

My initial guess is that each line of the Jenkins shell script is a new shell. But doing repeated echo $$ on separate lines shows that's not the case.


Answer:

su doesn't enter an interactive session when in a non-interactive session the way it does in an interactive session.

In a shell script you get to run a single command in the su context su <user> <command>.
