Can you use grep / awk on variables instead of files?

What I want to do is check if a pattern is found in a string variable. I'm clearly missing either a very useful command or something more even more fundamental, i.e, how to get a string variable to be piped into grep instead of a file name.



how can I check if $Y is part of $X

is this possible with grep / awk?

How about echo?

[hector ~]$ X='abcdef'
[hector ~]$ Y='cd'
[hector ~]$ echo $X | grep "$Y"
