view next line of matched word

You sometimes would like to show the very next line(s), which contain specific word(s).

I have to confess that I did not know there is a useful option in grep to achieve this sake... I have been using, say, some script to extract lines, which I would like to check.

You can achieve this with -A option. For example, if you would like to show the next line, which contains specific word, then following command give you the answer:

$ grep <WORD> -A 1 <FILE>

If you would like to see more line(s), increase argument after -A option.

So easy...
