I am trying to get a log size of the multibranch job. The problem is when the branch name contains some underlines for example "test_multi_underline_job_jenkins" so the Jenkins stores the log file on the strange job's folder - it changes the all underlines to the middle dash and also changes the 3th word to something random so the folder name is like "test-multi-u.v0fcf8.-job-jenkins".

How can I know exactly the folder name for a specific job?

Thanks.
