noob problem installing

trying to use hashcat on a 64bit laptop running gnome 3.18.3

(im a linux noob btw)

have been using this guide to install and start using
https://techglimpse.com/password-cracking-with-hashcat/

i have downloaded the zip and extracted the 64bit bin to usr/bin and then made the shortcut
ln -s /usr/bin/hashcat-cli64.bin /usr/bin/hashcat

which all worked fine - however if i try to use hashcat anything it tells me it doesnt recognise the command


What else do i need to do to get started?

Thanks
