Where did you install it?

~~Since you are on an Arch based distro you should be able to install egctl from the aur: https://aur.archlinux.org/packages/egctl-bin

I’m not that familiar with Endevour OS, but maybe you can do something like yay -Syu egctl-bin~~

The tool should be installed somewhere your path envkronment variable points to and then you’ll be able to execute it from your shell (terminal)

Edit: I linked the wrong tool, sorry. Thanks for pointing it out.

Now the only question is: how did the blacksmith get the sword up there in the first place?
