    Question Unanswered: grep -n help

    Hi

    I am trying to create a script that greps a file for a character then returns the line number of that character. This is fine but when you use grep -n it returns the line number and the whole line of text. Is there away of getting it to just come back with the line number ?

    example
    Code:
    cat filename | grep -n "="
    this returns

    Code:
    16:=============================================================================
    =======================================================
    19:=============================================================================
    =======================================================
    22:=============================================================================
    =======================================================
    25:=============================================================================
    =======================================================
    28:=============================================================================
    =======================================================
    31:=============================================================================
    =======================================================
    35:=============================================================================
    =======================================================
    38:=============================================================================
    =======================================================
    41:=============================================================================
    =======================================================
    44:=============================================================================
    =======================================================
    when all i need is the line number

    Cool


    Try this:
    Code:
    grep -n "=" filename|cut -d':' -f1
