As you already know, openbsd comes with VI and not VIM. Just for security purpose as well. So, let’s install VIM on OpenBSD ?

# echo $PKG_PATH

#export PKG_PATH=http://ftp.openbsd.org/pub/OpenBSD/`uname -r`/packages/`arch -s`    
#echo $PKG_PATH                                                                   
http://ftp.openbsd.org/pub/OpenBSD/5.6/packages/amd64
#pkg_add vim
