using grep with echo command

Is there a way to use a grep command with an echo command so that the output will show only part of what is being echoed?

Welcome.

The short answer is yes. You probably don't need echo at all, but can you clarify more precisely what you mean? Also show what you have tried so far so we have a better idea of both what you want and where you are along the way there.

Code:

man grep

maybe it's enough to answer your question.

I use an alias to colorize my grep results/hits.
If that sounds like what you'd like stick this in your ~/.bashrc

Code:

alias grep="grep --color=auto -i"

Can you be more specific?

If you use grep -o it will echo that pattern only and not the entire line.

For example

echo "My name is Azat, I love linux" | grep -o linux
linux

This will return the pattern linux and ignore the rest.
