    select a certain line from file

    hi again!

    I'm writing a bash script and I wonder how can I select a certain line from a file.For example I only want the line that starts with
    a specific word(given that there's only one starting with this word)
    and then by using sed perform an operation to this certain line

    Code:
    Residence: info info2 info2
    So I want the line that starts with Residence: and then do something with sed to this line

    Given that sed will find the line for you as well, what's the point of using something else?

    sed '/pattern/x' file

    pattern is what you want to look for
    x is what you want to do
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
