How do I add directory to path for MacOS 10.15 Catalina? Following along Wireshark 101 by Laura Chappell for a Network Forensics class, and in the foot notes it says to Google "add directory to path for <operating system="">", which I did, but couldn't find a definitive answer. I also found in the Applications folder a .pkg install file to "Add Wireshark to the system path.pkg" and that seemed to add a directory in the "About Wireshark/Folders" section in the Application but in does not have a 'Location'. The Chapter 8 is about using command line to run editcap, mergecap, and tshark command lines.
What script do I have to run in Terminal to assign the directory a path? Will creating the directory path in Terminal give access to the 'command-line tools'? Are these command line tools OS exclusive to Windows and, if so, what are the Mac OS equivalent (if any)?
