here string

The symbol for a here string is «< . A here string puts whatever input you want into a command. Like bc «< 2+2 sends 2+2 into the calculator and it will come back as 4. So it does the operation in one step instead of going into the calculator and typing 2+2 or whatever you want to solve.

* Notes from when we talked about here strings and the binary calculator.
