How to use the cat command to find a specific word in a textfile

Question

I did some research but I was unable to find anything to help, I need to find the word "war" in a text file, I know that I can use the cat command, but I need to modify it somehow, can someone help?

Answer 1

You can do it by grep. You do not need cat for that.

grep -w war file_name

You can use cat too, if you like

cat file_name | grep -w war

but it is longer.
