How to parse lines from a file on a FTP server without downloading it [closed]

I want to parse a line from large files on a FTP server without downloading them, using Linux command line.

Something like this comes to mind:

wget <ftp_file> | grep <something_from_a_line>

Is there a way to do this?

Answer

Reading a remote file from a client machine implies that you download it (explicitly or implicitly). Otherwise you must find some way to connect onto the server and read the file locally on the server.
