First, try /bin/bash instead. On most systems, /bin/sh and /bin/bash are not 
the same shell. Since "history" is a bash built-in command, it makes sense 
that /bin/sh can't find it. Second, why not just remove .bash_history 
instead? If the idea is to clear your shell history, this should work:

#!/bin/sh
rm ~/.bash_history
