NAME¶

clog - colorized log tail

SYNOPSIS¶

clog [-h|--help] [-v|--version] [-d|--date] [-t|--time] [-f|--file <rc>] [ <section> ... ]

DESCRIPTION¶

Clog is a filter command, which means it copies its input to its output. But if lines in the input match certain patterns, actions are taken. These are called rules. The rules are defined in ~/.clogrc as regular expressions, and the actions are specified, to colorize either the line or matching pattern, or perhaps to suppress the line. If --date is specified, the current date, in the form YYYY-MM-DD is prepended to all lines. If --time is specified, the current time, in the form HH:MM:SS is prepended to all lines. If --file is specified, an alternate configuration rc file may be specified. Default is to ~/.clogrc One or more section arguments may be specified. If none are provided, 'default' is assumed. A section corresponds to a rule set defined in ~/.clogrc. and allows the use of one .clogrc file to serve multiple different uses of clog. If more than one section is specified, the rules sets are combined, in the sequence found.

CONFIGURATION FILE AND OVERRIDE OPTIONS¶

Clog reads its configuration from a file in the user's home directory: ~/.clogrc. The format of the rules is: If the pattern is surrounded by / characters, it is interpreted as a regular expression. If the pattern is surrounded by " characters, it is interpreted as a string fragment. The section is simply a way to allow multiple rules sets, so that one .clogrc file can serve multiple uses. The pattern may be any supported Standard C Library regular expression. Action must be one of 'line', 'match', 'suppress' or 'blank'. Note that there is a default section, called 'default'. Putting rules in the default section means that no section need be specified on the command line. Any color can be used, in both the 16- and 256-color space. Some examples are: Instead of coloring the whole line, specifying 'match' instead will only color the parts of the line that match.

EXAMPLE Rulesets¶

Here is an example ~/.clogrc file.
