    Introduction



    Hi all,
    I have been working the whole day on a one-liner that can do a search replace.. No results jet...

    What I need to do:
    I have a datafile called data.txt
    the content of the datafile:

    1? john
    2? paul
    3? mary
    .....
    11? stuart
    12? peter

    And so on. There are 28 lines in the file.

    Now I want to change the line that begins with "1?" to "1? Has left the company."

    It should be a oneliner that will be called from a batch script.
    something like:
    perl -p -i -e "s/search/replace" "data.txt"

    Does anyone have an idea.. I came up with several variations but ether nothing got replaced or 1 and 10 and 11, etc got replaced.

    Any help would be most welcome.

    Regards,
    Pieter

    Are you looking for this.

    Code:
    perl -p -e "s/^1[?]/1? Has left the company./" data.txt
    
    Output:

    1? Has left the company. john
    2? paul
    3? mary
    .......
    11? stuart
    12? peter
