in reply to "em" - Emphasize text using regular expressions

GNU grep used with --color option and GREP_COLORS environment variable can do something similar.

    With this tool you can just type
    tail -f logfile | em "interesting"

    ...instead of
    export GREP_COLOR="33;1" && tail -f logfile | grep "interesting" --colour

    And you can do more than one regex/color in the same filter.
