Pipe into command stored in bash variable

Question

I enter two command in bash:

1. $export g='grep "something"'
2. $echo "something and another thing" | $g

But it doesn't work.

I want the second command to be evaluated by bash as : echo "something and another thing" | grep "something"

What should I do for that?

Answer 1

use an alias.

alias g='grep "something"'
echo "something and another thing" | g
