    Hello Ashish

     

    1) awk '{ print $3 }' = separate the previous output by spaces and take the third value.

    https://en.wikipedia.org/wiki/AWK

    2) xargs -l {} = take the stdin (by line) and use it in the next command when characters '{}' are shown.

    BTW, I would appreciate if you mark my answer as "the best" or give me some upvote.

     

    KR,

    Dario.
