-a, --auth.log
    Parse /var/log/auth.log for matching lines

    ^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$

-P, --append-prefix PREFIX

-S, --prepend-suffix SUFFIX
    Prepend SUFFIX to rule suffix. Option can be given multiple times

-r, --rule-file RULEFILE
    Use file RULEFILE for rule input

EXAMPLES
With logcheck-test you can easily write and test new rules.

Test a single rule against /var/log/syslog:
    logcheck-test -s "RULE"

Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix:
    logcheck-test -l ~/log -e -P "kernel " "RULE"

Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log:
    logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel

Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match:
    logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i

EXIT STATUS
On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching.

An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream.
