Editing Batch processing (section)

===Ongoing===
Non-interactive computation remains pervasive in computing, both for general data processing and for system "housekeeping" tasks (using [[system software]]). A high-level program (executing multiple programs, with some additional "glue" logic) is today most often called a ''script'', and written in [[scripting language]]s, particularly [[shell script]]s for system tasks; in [[IBM PC DOS]] and [[MS-DOS]] this is instead known as a [[batch file]]. That includes [[Unix|UNIX]]-based computers, [[Microsoft Windows]], [[macOS]] (whose foundation is the [[Berkeley Software Distribution|BSD]] Unix kernel), and even [[smartphone]]s. A running script, particularly one executed from an interactive [[login session]], is often known as a [[job (Unix)|job]], but that term is used very ambiguously.

"There is no direct counterpart to z/OS batch processing in PC or UNIX systems. Batch jobs are typically executed at a scheduled time or on an as-needed basis. Perhaps the closest comparison is with processes run by an [[at (command)|at]] or [[cron]] command in UNIX, although the differences are significant."<ref name="whatis">{{cite web|last1=IBM Corporation|title=What is batch processing?|url=https://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm.zos.zconcepts/zconc_whatisbatch.htm|access-date=Oct 10, 2019|website=zOS Concepts}}</ref>
