grep_to_end.sh

function grep_to_end () {
    if [ -z $1 -o -z $2 ]; then
        echo "Usage:\ngrep_to_end 'regex' file1 [file2 file3 ...]"
        exit 2
    fi

    for i in $(grep -n -m1 $1 "${@:2}"); do
        filename="$(cut -d':' -f1 <<< $i)"
        lnum="$(cut -d':' -f2 <<< $i)"
        echo "\n--\n$filename:"
        tail -n +$lnum $filename
