Join Kevin Skoglund for an in-depth discussion in this video grep: Multiple files, other input, part of Unix for Mac OS X Users.
What if we want to grep from multiple files or search inside directories?…There are a couple of ways to do it.…One is we could just say well, grep for Apple inside and then provide the file…path, a directory in this case.…So let's just say we're going to use the current path.…The dot represents the current path.…We could just as easily type Users/Kevin /unix_files, same thing. It comes back and says…I didn't find anything.…It's because we've given it a directory.…If we want it to do it in this way then we need to put the -R option in front…of it for recursive.…
Recursively look inside here, meaning check all of the files that are in this…directory and then go into the directories below that and look inside those and so on.…The same option that we used with copy, move, and remove earlier. So grep…recursively for apple inside this directory.…So whenever we use a directory, we want to use -R just like we did when we…were doing copying.…So now it tells me not only the matches it made but the file where it occurs.…
