How do I permanantly unistall nmap? Installed nmap from https://nmap.org/download.html to check it out, got bored, moved the app name: zenmap to trash and emptied it. However, if I run the nmap command in terminal, it still works...
The nmap installer from https://nmap.org/download.html installs  


the application /Applications/Zenmap.app
some binaries in /usr/local/bin
support files in other directories within /usr/local


To remove, run

sudo rm -r /Applications/Zenmap.app
sudo rm /usr/local/bin/{ncat,ndiff,nmap,nmap-update,nping}
sudo rm /usr/local/share/man/*/man1/nmap.1
sudo rm /usr/local/share/man/man1/{ncat,ndiff,nping,nmap-update}.1
sudo rm -r /usr/local/share/{nmap,ncat}
