To install Pulse Secure for Ubuntu 20.04, it is a bit complicated since the support isn't great.

First, we'll want to go through the form at https://www.pulsesecure.net/trynow/client-download/. You'll get an email with download links to the latest versions of pulse secure. Download the Linux one with the deb file and then you can install it using dpkg from your downloads folder.

Bash is the JavaScript of systems programming. Although in some cases it's better to use a systems language like C or Go, Bash is an ideal systems language for smaller POSIX-oriented or command line tasks. Here's three quick reasons why:

  • It's everywhere. Like JavaScript for the web, Bash is already there ready for systems programming.
  • It's neutral. Unlike Ruby, Python, JavaScript, or PHP, Bash offends equally across all communities. ;)
  • It's made to be glue. Write complex parts in C or Go (or whatever!), and glue them together with Bash.
