Spacing is important. Because of the space in your command, this doesn't do what you expect:

user= whoami

What that does is define an empty variable called user, and then calls the whoami command with that empty variable added to the environment. The "pbsh56" you see is from the whoami command, not from the echo.

What you want is

user=$(whoami)
echo $user
cd /home/$user
