I would like to be able to run 7zip from the command line on Mac. Does anyone have instructions on how to set this up?

To install p7zip using Homebrew, first update your brew formulae to be sure you are getting the latest p7zip.

$ brew update

Use Homebrew to install p7zip:

$ brew install p7zip

Add all files in the sputnik directory to the compressed file heed.7z:

$ 7z a heed.7z sputnik

Unzip heed.7z:

$ 7z x heed.7z

    I had to come here to find out that the command isn't p7zip, it is 7z...

On the download page of 7-zip, there are several options for OS X. Unfortunately, they seem to be with a GUI, or not available at the moment.

You can download p7zip though.

p7zip is the command line version of 7-Zip for Unix/Linux, made by an independent developer

It is distributed as Linux binaries and in source code form on Sourceforge.

Download the source code, and run make in the folder you extract the archive to. It will automatically build 7za for your OS. You might need Xcode and its command line tools for this to work.

$ cd Downloads/p7zip_9.20.1
$ make
$ cd bin
$ ls
$ ./7za

    Before "make" I had to issue command "cp makefile.macosx_64bits makefile.machine" Mar 16, 2015 at 16:47

If you only need to extract archives, unar (a command line version of The Unarchiver) also supports 7zip.

  • Thank you for introducing me to The Unarchiver. The GUI version works great on Mac too.

p7zip is not maintained anymore. It's been at 17.xx for years. 7zip is at 23.xx as of Nov 2023. p7zip is missing important features like multi-core parallel compression and extraction

brew install sevenzip will install the package still maintained by the original developers (https://7-zip.org).

To use, 7zz --help
