On the Windows command-line, I can extract archives like this:
7za e somefile.zip
I know 7-Zip supports .rar in the GUI, but can it be done in commandline mode?

Yes, you can extract .rar archives from the command line, but only if you use 7z, not 7za:
7za.exe (a = alone) is a standalone version of 7-Zip. 7za.exe supports only 7z, lzma, cab, zip, gzip, bzip2, Z and tar formats. 7za.exe doesn't use external modules.
The above applies to both Linux and Windows and the syntax is identical:
Windows:
C:\Users\me>7z e dll-test.rar

1Fair warning: `7za.exe` doesn't support `.rar` only the `7z.exe` does. – Matt Clarkson Feb 18 '14 at 15:00

To get the `7z` command, and not just the `7za` command on Fedora, I had to also install the `p7zip-plugins` package. – zymhan Jul 23 '20 at 15:19

How do you get 7z.exe without admin privileges though? It seems the only way to do it is to install it in a UAC protected location. 7-Zip Portable would be a good example of it, but they bundle and run their own code instead of giving you a zip of the binary, so I don't trust them – Pluto Jan 25 '23 at 23:18

You can see all command lines in the "7-zip.chm" help file (from the installation):
Extracting rar is like extracting all files:
7z x archive.rar
For example:
"C:\Program Files\7-Zip\7z.exe" x "C:\Archives\test file.rar"
