I wanted to locate my zsh in my /usr/local/bin directory on my mac using the command:

ll | grep zsh

But I accidently type

ll | zsh

and now when I try to run command lit

git status

or

pip --version

it either tells me the exec format error or simply does nothing. Even brew update does not do nothing, not even printing an error message.

I tried restarting my mac and my shell. I checked the the PATH variable is good. What can I do?
