cre is a simple text colourizer. It prints all it gets on STDIN (or in files
provided as arguments), but for every regexp passed with -e option cre makes
the match coloured.
cre is similar to ack --passthrough or an abuse of grep,
grep -E --color '^|pattern', but cre is a little simpler to use and it
colours every pattern passed with -e with different colour (up to
6 patterns are supported).
cre uses PCRE syntax, or exactly, Perl's regexp syntax.
cre requires Perl 5.10 to run.
# find all "root" occurrences and mark them with red
cre root /etc/passwd
# find "/bin/zsh" shell and "/var/*" homes; shell will be red, home will
# be green
cre -e /bin/zsh -e '/var/[^:]*' /etc/passwd
