Suppose you want to append to a file that’s write-protected and can only be edited via sudo. Is that possible? It is!

A technique I discovered today is to use tee with sudo:

$ cat file.txt | sudo tee -a /etc/hosts

This lets me append the contents of file.txt to the write-protected /etc/hosts file by entering my password.

What are your thoughts on this? Let me know!
