Install Postman on Linux through CLI without Snap

install_postman.sh

# This script basically automates the official Postman installation guide for Linux:
# https://learning.postman.com/docs/getting-started/installation-and-updates/#installing-postman-on-linux

# 32 or 64-bit?
BIT=$(getconf LONG_BIT)

# Download the appropriate version
wget -O ~/postman.tar.gz "https://dl.pstmn.io/download/latest/linux${BIT}"

# Extract the archive in /opt
sudo tar xvf ~/postman.tar.gz -C /opt/

# Remove the downloaded archive
rm ~/postman.tar.gz

# Make the app accessible from a launcher icon 
echo "[Desktop Entry]

Thanks.
This step was necessary too for xdg-open to open postman:
sudo ln -sf /opt/Postman/app/Postman /usr/bin/postman
