Linux tips | export environment variables | use sed to update multiple files

Updating config files with Linux environment variables is something you may need to do when setting up Flask, Nginx, or Django projects. Here we see how to update multiple config files with one line, using sed. Sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline) - rather than look up the syntax each time, try and use an example like this many times and you'll do just fine. 🌏 https://linux.die.net/man/1/sed Visit redandgreen blog for more Tutorials ========================================= 🌏 http://redandgreen.co.uk/about/blog/ Subscribe to the YouTube Channel ================================= 🌏 https://www.youtube.com/c/DrPiCode Follow on Twitter - to get notified of new videos ================================================= 🌏 https://twitter.com/RngWeb 👍 Become a patron 👍 🌏 https://www.patreon.com/drpi Buy Dr Pi a coffee (or Tea) ☕ https://www.buymeacoffee.com/DrPi Proxies ================================================= If you need a good, easy to use proxy, I was recommended this one, and having used ScraperAPI for a while I can vouch for them.
