How can I grep key word and the next four words. For example let's say we have this paragraph:
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 167 Stack Exchange communities.
I wan to grep the key word "Exchange " and the next four words so the output is "Exchange is where users like"
I used :
grep -Eo "Exchange"
What I must add to this command to control the number of greps (words, numbers, charters ,...) after a key word
