I have a bunch of .html files in a directory. I want to look through each file and match a pattern (MD5). All of that is easy enough. The problem is I need to know what file the match was found in.
cat *.html | grep 75447A831E943724DD2DE9959E72EE31
Only returns the HTML page content where the match is found, but it doesn't tell me the file which it was found in. How can I get grep to show me the filename where my match is found?
