This is help for command or file iniside Individual commands/files to compare after you push the "add" button
Sorry, I do not know how to put help into repeatable element. And command/file is heart beat which should have had help.
The list of commands that outputs list of Strings for compare. For example:
rpm -qa or or env
Or just files to be read, if exists (otherwise interpreted as command)
command is run/file located in workspace. Is processed, and stored where it should be - jenkins_home/jobs/jobname/buildid/rpms-{all,new,removed,stderr}.txt
Warning, empty output from command do is not opening output stream, so it is considered as null, not epty (unlike empty file)
