You are.  However the 'sh' command calls a specific interpreter (/bin/sh).   
When you execute an executable file (e.g., made executable with 'chmod +x'),  
the interpreter is chosen according to the line starting with "#!" at the  
beginning of the script, the shell if there is no such line (and no  
interpreter if the file is an executable binary).  For instance, those "#!"  
call for different interpreters for different programming languages (or with  
different options for the same language):
#!/bin/bash
#!/bin/sed -f
#!/usr/bin/awk -f
#!/usr/bin/perl -w
#!/usr/bin/python
#!/usr/bin/python -OOt
#!/usr/bin/python3
