Small calculator, on command line

---

Overview

The function below allows you to add the function calc shell. It is often convenient to have a small function to perform some simple operations, without having to search everywhere to find a calculator, or to launch a graphical gui.

Just add the following line on ~/.bashrc file:

function calc() { awk "BEGIN { print $* }" }

For running the program, you must use quotes.

Function usage example

calc '3+2'

Be careful

Since we have added the function in the .bashrc file, you have to logoff and logon.
