How to use alias and bash builtin functions?

 #+BEGIN_SRC sh :session :results output
   echo $SHELL
   echo $HOME
   source ~/.bashrc
   alias | wc
   env | grep HISTTIMEFORMAT
   history | wc
 #+END_SRC

 #+RESULTS:
 : /bin/bash
 : /home/osiris
 :       0       0       0
 : HISTTIMEFORMAT=%Y-%m-%d %H:%M
 :       0       0       0

Thanks!
