What software / package managers are frequently installed on macOS that can be updated via the command line?

The software / package managers could either be included with macOS, or they could be software that many people (including myself) might have installed.

I'm writing a zsh script to update all such software on my machine, like:

  • gem
  • homebrew
  • oh my zsh
  • pip
  • sdkman

I want to ensure that I'm not missing anything that can be updated.

I'm currently skipping updating cpan, because whenever I've tried, I get tons of errors. Are there any other command-line software updaters that frequently experiences errors while updating?

Are there any other package managers that I should use instead of one of the above?

I know that this contains multiple questions, but they're all related, so I figured it makes sense to group them together.

  • I don't really understand the question. I see you refer to homebrew and sdkman, which already can keep packages (=software) up to date. Why do you want your own script to do the same? – Saaru Lindestøkke Mar 10 '20 at 16:02
  • @SaaruLindestøkke Most of the time, you need to run multiple commands to update each single package manager. Also, I can run one script that will update every package manager I use. My current top level script calls 6 other scripts, each of which is 2 - 6 lines of code (besides shebangs & whitespace). So, I can just run update instead of having to remember & retype 30 or so lines of code (which sometimes parses the responses of previous commands to be input for subsequent commands). – XDR Mar 10 '20 at 18:22

Two other package managers are MacPorts and Fink.

  • Does this update everything you’ve used homebrew to install, or just homebrew itself? – Eric S Mar 19 '20 at 1:56
  • @jmh I know how to update the software listed in my question (which includes hombrew), I just want to know what other software that might be on my machine can also be updated. e.g., I didn't know that Oh My Zsh could be updated until recently, so I accidentally missed out on updating that. Once I know what can be updated, I can read the relevant documentation to learn how to update it. – XDR Mar 19 '20 at 10:41
