What Others Think

Hmm... cute. An alternative is to use grep as a colouring filter: grep --color -e "[0-9]\+" -e "$" The -e "$" matches end-of-line, so all input lines are displayed.

Awk version: awk '{ gsub(/[0-9]+/, "[&]"); print }'

Nice, but when would you ever need this? I don't tend to read text with numbers embedded in it unless it's about "L10n" (localization), "a11y" (accessability), "i18n" (internationalization), "w3c" (world wide web consortium), or "Da5id" (a character from the book Snow Crash).
