cet - console emphasis tool
cet.pl REGEX1 [COLOR1] [REGEX2 [COLOR2]] ... [REGEXn [COLORn]]
cet.pl is a command line tool for visually emphasizing text in log files etc. by colorizing the output matching regular expressions.
REGEX is any regular expression recognized by Perl. For some shells this must be enclosed in double quotes ("") to prevent the shell from interpolating special characters like * or ?.
COLOR is any ANSI color string accepted by Term::ANSIColor, such as 'green' or 'bold red'.
Any number of REGEX-COLOR pairs may be specified. If the number of arguments is odd (i.e. no COLOR is specified for the last REGEX) cet.pl will use 'bold yellow'.
Overlapping rules are supported. For characters that match multiple rules, only the last rule will be applied.
In a system log, emphasize the words "error" and "ok":
tail -f /var/log/messages | cet.pl error red ok green
In a mail server log, show all email addresses between <> in white, successes in green:
tail -f /var/log/maillog | cet.pl "(?<=\<)[\w\-\.]+?\@[\w\-\.]+?(?=\>)" "bold white" "stored message|delivered ok" "bold green"
In a web server log, show all URIs in yellow:
tail -f /var/log/httpd/access_log | cet.pl "(?<=\"get).+?\s"
BUGS AND LIMITATIONS
Multi-line matching is not implemented.
All regular expressions are matched without case sensitivity.
Nothing. You should not attempt to use this module for anything. Perhaps what you are really looking for is the script: cet
