Is there at least a prompt? I dislike and distrust tools which write to those files on their own. My shell’s startup files are organised how I want, with different sections depending on what’s relevant. It’s the entry point to every terminal session so I know what every line does. I don’t appreciate when a tool decides it’s OK to latch itself to every terminal session in a disorganised manner without permission, especially since those additions are seldom removed when the tool is uninstalled.
