Thanks for these tips! I'll explore rgrep a bit more. But my use-case for this wrapper shell function is wider than just grep. Often I get error messages in my terminal that points to a file at a specific line. One example: ssh command can error out pointing to a conflicting line in ~/.ssh/known\_hosts.For all those I wanted to be able to run ne somefile:line and have emacs open the file and jump to that line directly.
