This is the detail level of the report. level can be a positive integer, or high, med, low, which correspond to the integers 10, 5, and 0, repectively.

This will force Logwatch to process only the set of logfiles defined by log-file-group (i.e. messages, xferlog, ...). Logwatch will therefore process all services that use those logfiles. This option can be specified more than once to specify multiple logfile-groups.

This will force Logwatch to process only the service specified in service-name (i.e. login, pam, identd, ...). Logwatch will therefore also process any log-file-groups necessary to process these services. This option can be specified more than once to specify multiple services to process. A useful service-name is All which will process all services (and logfile-groups) for which you have filters installed.

Print the results to stdout (i.e. the screen).

Mail the results to the email address or user specified in address.

You can specify a date-range to process. Common ranges are Yesterday, Today, All, and Help. Additional options are listed when invoked with the Help parameter.

Each log-file-group has basic logfiles (i.e. /var/log/messages) as well as archives (i.e. /var/log/messages.? or /var/log/messages.?.gz). When used with "--range all", this option will make Logwatch search through the archives in addition to the regular logfiles. For other values of --range, Logwatch will search the appropriate archived logs.

For debugging purposes. level can range from 0 to 100. This will really clutter up your output. You probably don't want to use this.

Save the output to file-name instead of displaying or mailing it.

Look in directory for log files instead of the default directory.

Use hostname for the reports instead of this system's hostname. In addition, if HostLimit is set in the logwatch.conf configuration file (see MORE INFORMATION, below), then only logs from this hostname will be processed (where appropriate).

Inhibits additional name lookups, displaying IP addresses numerically.

Suppress the logwatch log, which informs about the old files in logwatch tmpdir.

Displays usage information.
