Edit and write .bat files on Mac

As others have stated, Macs do not use .bat files. If you

are trying to create some process to do a series of system tasks

there are multiple ways to do it.

Applescript - https://developer.apple.com/library/content/documentation/AppleScript/Conceptual /AppleScriptX/AppleScriptX.html

Automator -

In the Mac Help menu, just type in automator.

In addition, you can create command line scripts as well using

the built in UNIX Bash shell. The article is for Linux but is still

valid for any *NIX environment:

In addition, you can create such scripts in Swift language. I believe

you need to install Xcode to get the Swift interpreter shell for Terminal.

Batch files can be written/edited in Notepad or Stickes but .BAT files are for Windows OS, not Mac.

The OS X equivalent is Apple Script

By ".bat" files are you referring to the MS DOS/Windows type batch files?
