Cannot write to file with shellHook

[winston0410]

Describe the bug I am trying to write to a file from the shellHook.

{...}:
pkgs.mkShell {
  shellHook = ''
    echo "hello" >> $HOME/hello
  '';
}

And I cannot find the file after I have entered the dir.

I have tried this example from this issue, which the hook is running.

with import <nixpkgs> {};

mkShell {
  shellHook = ''
  export FOO=BAR
  '';
}

To Reproduce Steps to reproduce the behavior:

1. lorri init
2. direnv allow
3. Paste the code in

   {...}:
   pkgs.mkShell {
   shellHook = ''
   echo "hello" >> $HOME/hello
   '';
   }

4. Exit and enter again, and check for output

Expected behavior I expect it will generate a file in $HOME/hello

$ lorri info
`lorri info --shell-file ./shell.nix`
lorri version: 1.5
GC roots do not exist. Has the project been built with lorri yet?

This is weird. I have built it by exiting  and entering more than once. Not sure if there is any insight from this output
