![]() ![]() This flag tells grep to print the matching filenames. This particular use of the grep command doesn’t make much sense unless you use it with the -l (lowercase "L") argument as well.Note that in this case, quotes are required around my search pattern. Since I tend to mark comments in my code with my initials ("aja") or my name ("alvin"), this recursive egrep command shows how to search for those two patterns, again in a case-insensitive manner: You can also perform recursive searches with the egrep command, which lets you search for multiple patterns at one time. In this example, the search is made case-insensitive by adding the -i argument to the grep command. This next example shows how to recursively search two unrelated directories for the case-insensitive string "alvin": Your recursive grep searches don’t have to be limited to just the current directory. If you haven’t used commands like these before, to demonstrate the results of this search, in a PHP project directory I’m working in right now, this command returns a list of files like this: As you’ll see below, you can also add -i for case-insensitive searches. ![]()
