qmake is not a directory

[Hannah1746]

I am trying to download Bandage on my mac laptop with Homebrew following the directions from https://github.com/rrwick/Bandage. When I get to step five I hit a wall.
cd /usr/local/opt/qt5/bin
works but when I try to get into the directory of qmake I get
Not a directory
But with I ls I get

What can I do?
