#Installation
In terminal, copy/paste the following to create a ubin
(user bin) folder if it doesn't exist already and add to paths.
sudo mkdir /usr/ubin
sudo chown $USER /usr/ubin
echo "export PATH=\"/usr/ubin:\$PATH\"" >> ~/.profile
Then move the calc.php
and calc
file over to /usr/ubin/
and make sure calc
is executable by chmod +x /usr/ubin/calc
