  1. error and fruits are the random files. I am trying to redirect the lines which do not contain small 'a' and want to sort if in reverse order. However, the command is not working

    NOT WORKING – cat fruits | grep -v a > error | sort -r error
    WORKING – cat fruits | grep -v a | sort -r > error
