Vim publishing script -

i'm looking vim script that, when save, duplicates changes second directory. in case second directory on vm can ssh to. suggestions?

if want manually add vimrc:

command! duplicatefileremotely !scp % user@remotehost:~/mylocation/ 

then call in command mode:

:duplicatefileremotely 

if want every time file saved add vimrc well:

autocmd! bufwritepost * :duplicatefileremotely
