There is a typo in "Batch commands stored in external files" part of section 3.5.6 In sentence "Changed made in this batch session do not persist to the myscript.txt file." "Changed" should be "Changes"
Moving to ON_QA. The changes should be available for review on the documentation stage within an hour or so from this comment. http://documentation-devel.engineering.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/
Verified in currently staged single-html administration and configuration guide.
