Write file from remote server to local directory?

Question

I want to do some grep-magic to a logfile on a remote server and write the result to a local file on my computer.

Is there an easier way than my 3 step solution:

1. do grep-magic and write file on remote server
2. copy from remote to local with scp
3. delete the file on remote

Answer 1

Just execute the command in the remote server through ssh and store the output locally:

ssh myuser@thatserver 'grep "aa"' > ~/myoutput.res
