McMyAdmin Assistance on Ubuntu

Im currently using Ubuntu to host a minecraft server, but as bukkit took a hit, mcmyadmin has been malfunctioning lately. fatal server errors, and such. can someone provide some assistance with editing the McMyAdmin.conf file and wiping out the server files to replace them with files already developed and coded.. how do i locate it, as i know how to get into the directory, but im currently lost as to what i do to edit it. my question is, how do i locate it in a default directory after doing ( cd ~/McMyAdmin ) on the terminal. i need to edit it using nano or VIM as i have both installed on Ubuntu 14.04. then how do i replace the server files with the ones i have on hand.

Thanks,
