This question already has an answer here:
I'm currently in the process of developing some shell scripts but have run into a problem: whilst I am able to execute numerous commands on my Mac, when I try to run it on other people's computers I get
Command not found errors indicating that they do not have the specific command line tools installed.
It is my belief that many of these tools come as a result of installing Xcode and other package managers like Homebrew. My question is: is there a list or another way of finding out if a specific command (tool) is pre-installed on a standard Mac computer (without Xcode installed) without having to manually test it on someone else's computer?
For example, this post hints that
git is pre-installed which is only the case if you have installed Xcode, otherwise,
git is unavailable.
P.S. For my specific case, I am wondering if
hexdump is pre-installed or not (without Xcode)
