Usage

lg [command] [command options] [query] <log-file1> [log-file2 ...]

The command is optional. When the command is missing, the implied command is "query", the given log file is parsed and the resulted events are matched against the query. Unless output filtering options are used, the events are displayed in their raw format, which is how they appear in the original log.

Commands:

• help
• version
• describe - displays a description of the events produced as the result of the parsing.
• time-gaps - identify time gaps in the log
• count (-c) - display the number of events that match the query.
• exclude (-x) - filter out the events that match the query, and only display those that do not match. This command is equivalent with the grep --invert-match (-v) option.
