    How can I extract certain strings from a variable?

    Hi, guys. I have one question.

    Assumed I have have a variable $userlist, it has the following contents:

    brownj
    smithk
    smithk2
    smithk3
    hynesp
    hynesp2
    leeb
    ...

    How can I write a bash script that extracts all the strings smithk, smithk2, smithk3, etc from variable $userlist, and assigns these strings to a new variable?

    Thanks a lot in advance

    -K.D
