ccze: A robust log colorizer
NAMEccze - A robust log colorizer
SYNOPSISccze [options] <logfile
DESCRIPTIONThis manual page documents briefly the ccze utility, which is a drop-in replacement for colorize, but written in C, to be faster and less resource-hungry. The goal was to be fully backwards compatible, yet superior with respect to speed and features.
OPTIONSThese programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.
- -a, --argument PLUGIN=ARGUMENTS
- Use this option to pass ARGUMENTS to the specified PLUGIN. The argument list is whitespace separated.
- -A, --raw-ansi
- If one wants to enable raw ANSI color sequences instead of using curses, this option does just that.
- -c, --color KEY=COLOR
- Set the color of the keyword KEY to COLOR, like one would do in one of the configuration files.
- -C, --convert-date
- Convert unix timestamp to readable date format (in oops and squid logs, for example).
- -F, --rcfile rcfile
- Read rcfile as a configuration file upon startup, instead of the default ones.
- -h, --html
- Instead of colorising the input onto the console, output it in HTML format instead.
- -l, --list-plugins
- List all available (loaded) plugins, along with their type and a short description.
- -m, --mode mode
- Change the output mode. Available modes are curses, ansi and html.
- -o, --options OPTIONS...
CCZE is able to toggle some of its features with this
option. You can toggle the scroll, wordcolor,
lookups, and transparent features, or you can fiddle with
cssfile. All of these are enabled by default, except
cssfile. One can turn them off by prefixing the option with a
With scroll, one can enable or disable scrolling. If the output is not redirected, it is wise to leave it enabled.
The wordcolor option makes ccze search for different keywords in unparsed input, and color those too. Since it is quite fast, and makes the output look better, it is recommended to leave this enabled.
However, lookups is an option that might be better to disable. When on, ccze will try to look up usernames, service names, and lots of other stuff, which will slow down coloring a great deal. If one is piping a long log through ccze, this option might be turned off to speed up the process.
With the transparent option, one can make CCZE treat black background colors as transparent - that means, a black background will appear transparent in a similar X terminal. If turned off, it will appear as black.
If cssfile is set, then CCZE will not inline the Cascading Style Sheet information into the outputted HTML, but include a link to the external stylesheet given in this paramater.
- -p, --plugin PLUGIN
- While the default action is to load all plugins (see the Plugins section below), when this option is present, only the specified plugins will be loaded. If one knows what kind of log will be piped through ccze, using this option may result in a slight speedup.
- -r, --remove-facilty
- Syslog-ng puts the facility level before log messages. With this switch, these can be cut off.
- Show summary of options and exit.
- -V, --version
- Show version of program.
PLUGINSDifferent programs have different kind of logs, and every kind of log ccze supports is implemented via a plug-in. They are by default located under /usr/lib64/ccze and $HOME/.ccze (so they can be overridden by the user easily).
At the moment, the following modules are bundled with the official release:
- For coloring apmd's logs.
- For coloring distccd's logs. (See distccd(1))
- For coloring exim's main.log. (See exim(8))
- For coloring fetchmail's log files. (See fetchmail(1))
- For coloring ftpStats compatible log files, such as Pure-FTPD's Stats log format.
For coloring apache-style access.log and error.log
files. (See apache(8))
As a side-effect, all compatible formats, like pure-ftpd(8)'s common-log format is also supported by this plugin.
- For coloring icecast/icecast.log and icecast/usage.log files. (See icecast(8))
- For coloring oops/oops.log files.
- For coloring php.log files.
- For coloring postfix logs. (See postfix(1))
- For coloring procmail's log file. (See procmail(1))
- For coloring proftpd's access.log and auth.log files. (See proftpd(8))
- For coloring squid's access.log, store.log and cache.log files. (See squid(8))
- For coloring sulog files. (See su(1))
- For coloring super.log files. (See super(1))
- For coloring generic syslog messages. (See syslogd(8))
- For coloring ulogd logs.
- For coloring vsftpd.log files. (See vsftpd(8))
- For coloring xferlog files. (See xferlog(5))
- /etc/colorizerc, $HOME/.colorizerc
- These files are the default configuration files for colorize, and are parsed by ccze for the sake of full compatibility.
This two are the main configuration files, in which one can change the
colors used by the program to his liking. See the comments in the
beginning of /etc/cczerc for a description on the files'
If neither of these files exist on your system, consider using the ccze-dump utility in the source tree, which dumps the default color set to standard output.
