This often happens if you've managed to launch a shell that doesn't set itself
up as "interactive" and/or acquire a control terminal.

Quick test - if you do a 'ps', does the shell process show up with a ? or with
a tty<something>?  If it shows ?, it hasn't gotten a control terminal.

Your shell may have a '-i' flag to make it interactive and/or a '-l' to
make it be a login shell, those flags may be an easy way to fix the problem.
