Recently, a customer has asked how to make Archer API calls using Linux shell, but we didn't have any examples and I'm a Windows guy. If anyone is familiar with Linux shell, can you post an example how to create a session token using Web Services and REST API? Thanks!
I saw someone was working on a python module for Archer. If the situation allows for installing python, then you could make those calls from a Linux machine. -- https://pypi.org/project/rsa-archer/
Otherwise, I think you are looking at CURL or Openssl as ways to establish a web connection from a command line / shell. I don't believe typical shells have a lot of built in web functionality, but there are usually a lot of utilities available to the shell for that.
