Synopsis:
        pcoc - Piped Command Output Colorizer.  Inspired by acoc.
 
Usage:
 
        $0 -f '<regex1>=<color1>' -f '<regex2>=<color2>'
 
$0 reads from a pipe and colorizes each line based on format (-f) parameters.
 
Arguments:
 
-f '<regex>=<color>'  Required, multiple values okay. 
 
        <regex>: A regular expression from which \$1 will be colorized
 
        <color>: One or more colorization keywords, see perldoc
        Term::ANSIColor, but briefly they are:
 
        boldness:
                bold
        foreground:
                red yellow green blue magenta cyan black white
        background:
                on_red on_yellow on_green on_blue on_magenta on_cyan
                on_black on_white
 
Examples:
 
        #highlight the account's shell in bold green
        cat /etc/passwd | $0 -f '.+:([^:]+)\$=bold green'
 
        #... and the username in red with black background
        cat /etc/passwd | $0 -f '([^:]+)=red on_black' -f '.+:([^:]+)\$=bold green'
