Hi, I found myself run into this situation quite often:
looking for certain keyword in a pile of file.
e.g: cat *.(file extension) | grep <keyword>
problem is, the result doesn't tell me which file(s) has the keyword i'm looking for. rather it shows a list of lines with the keyword.
where can I edit, so when i issue cat *.xxx | grep yyy would shows me which xxx that yyy is located?
