yup, I was missing it completely, I had to 'apt-get install sudo' as root and then from my account was able to use sudo – ovi Jan 19 '16 at 21:54

Maybe it isn't installed? Open your package manager and install the sudo package.

Also, try to use full path (if you have it installed)

/usr/bin/sudo

if that command work then include /usr/bin/ in your env variable PATH in ~/.bashrc

echo "export PATH="$PATH:/usr/bin"" >> ~/.bashrc

hopefully works ..
