Looking to unpack a bunch of files.7z via terminal.
Is there a command-line tool built in, available or I shall install an application that comes with a graphical interface?

You can install p7zip with Homebrew. So
% brew install p7zip
% 7za x myfiles.7z
Installing Homebrew as @EraserPencil suggested makes sense as the OP might need more programs in the future, which would be at his fingertips then. You can install Homebrew with
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
It should be noted there is 7z e as well but as commented by @Qback, this does almost never do what you want if you have subdirectories in the archive.

I have 7zip installed as well. Unfortunately, it said that the archive is damaged and failed to extract the file. Tried installing 7za and it worked like a charm.– XonshizMay 15, 2019 at 12:20
The command line version of Unarchive can extract .7z files.

MacOS does not handle the .7z format natively.
The UnArchiver is my favourite tool for handling .7z and many other formats. It is available as both an application and a command line tool if that is how you prefer to operate.

Apples "Archive Utility" handles 7z these days - the question whether built-in command-line-tools can also handle it remains... Aug 14 at 15:33
If you don't want to install homebrew, you can install keka (which is an excellent gui for (un)compressing btw) and then link to the included version of p7zip found at Keka.app/Contents/Resources/keka7z
In order to make it function from the command line, I symlinked it into my /usr/local/bin
> ln -s /Applications/Keka.app/Contents/Resources/keka7z /usr/local/bin/7z
> 7z -h
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=utf8,Utf16=on,HugeFiles=on,64 bits,4 CPUs x64)
Modified by aONe for Keka
Usage: 7z <command> [<switches>...] <archive_name> [<file_names>...]
[<@listfiles...>]
We also found another totally free GUI solution that can run on macOS from this other similar question
Keka - the FREE macOS file un/archiver.
Turns out that, as of the time of writing, the official 7z distribution has a mac cli client download - currently 7-Zip 21.07 (2021-12-26).
Download, unzip then run - works beatifully:
$ /Users/me/Downloads/7z2107-mac/7zz x some.7z
The first time you run it will fail with the "Unknown developer" prompt - you must give it permissions in the System preferences dialog
While you got an error like this
MacBook-Air ~ % brew install p7zip
Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)!
To rerun under ARM use:
arch -arm64 brew install ...
To install under x86_64, install Homebrew into /usr/local.
Use bellow code for M1 Chip Mac
arch -arm64 brew install p7zip

highly required
arch -arm64in M1 Chip MacBook, if you try to install withoutarch -arm64then got an error.– VivekMar 4, 2022 at 9:29 -
Then your setup is strange. Works without that for me (and others). May be worth asking a new question for this so people can help you to avoid this.– nohillside ♦Mar 4, 2022 at 9:30

Setup is not strange, M1 Chip architecture is
arch -arm64that's why we need to install any brew command with the same architecture, other intel base mac no need to addarch -arm64.– VivekMar 4, 2022 at 9:43 -
arch is only required if you want to pick a specific architecture from an universal binary. By default an M1 machine will automatically pick arm64 without any help from the user (unless you set your Terminal to run with Rosetta, but this isn‘t the standard case).– nohillside ♦Mar 4, 2022 at 9:54
Because you are familiar with CLI and coming from a Linux background, you could try Installing GNU-tar on Mac
You'd first need to install Homebrew,
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
then run brew install gnu-tar. Think of brew as the yum, or apt-get equivalent.
Then you can use gtar on your Mac.
# on Mac
$ gtar czvf example.tar.gz example
example/
example/bla.txt
# send it to CentOS
# login to CentOS
$ tar xzvf example.tar.gz
example/
example/bla.txt
