`git clone` from command line leads to unexpected GitX SSH Remove Password dialog

Question

In a terminal, when I try to

$ git clone <rep>

this happens

It's disturbing when you don't expect it.

Why does this happen, and how do I get rid of it?

Answer 1

git can use whatever is pointed to by the envariable SSH_ASKPASS (cf. here) as a helper when it needs a password, and something in GitX (specifically, GitX-dev) causes it to write this variable to use a tool internal to the GitX.app bundle.

To get rid of it in bash

unset SSH_ASKPASS
