M-x grep command is very useful in a number of situation, because, for example, it give you direct access to all matched file …
But there is not so intuitive how to use grep when opening file via ssh, this is the trick:
First generate a key pair and upload public part to the remote server:
(suppose remote host/user is B/b)
ssh-keygen -t rsa #... ssh b@B mkdir -p .ssh cat ~/.ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys' ssh-add
be sure to use ssh-agent in order to use ssh-add
So you will not be asked for a password every time you ssh
Every time you want to grep in emacs:
M-x grep
Run grep (like this): ssh -t b@B 'grep -nH -e include path_to_files/*'
where path_to_file is the path relative to home in remote host
NOTE: do grep command when visiting remote home in emacs (otherwise it will not find matched files)
that’s all
