logcheck-test [-q|-i] [-a|-s|-l FILE] [-e] [-P PREFIX] [-S SUFFIX] RULE logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE DESCRIPTION
logcheck-test parses a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX and a SUFFIX to write new rules easily. OPTIONS
-h, --help Show usage information -a, --auth.log Parse /var/log/auth.log for matching lines -s, --syslog Parse /var/log/syslog for matching lines -l, --log-file FILE Parse FILE for matching lines -i, --invert-match Show line that don't match the RULE or the RULEFILE -q, --quiet Suppress rule summary at the end of output -e, --surround-rule Surround RULE with standard prefix and suffix: ^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$ -P, --append-prefix PREFIX Append PREFIX to rule prefix. Option can be given multiple times -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. SEE ALSO
