NAME

       qsexec  - parses the data received via stdin and executes the defined command on a pattern
       match.

SYNOPSIS

       qsexec -e <pattern> [-t <number>:<sec>] [-c <pattern> [<command string>]] [-p] [-u <user>]
       <command string>

DESCRIPTION

       qsexec  reads  log  lines from stdin and searches for the defined pattern. It executes the
       defined command string on pattern match.

OPTIONS

       -e <pattern>
              Specifes the search pattern causing an event which shall trigger the command.

       -t <number>:<sec>
              Defines the number of pattern match within the the defined  number  of  seconds  in
              order  to  trigger  the command execution. By default, every pattern match causes a
              command execution.

       -c <pattern> [<command string>]
              Pattern which clears the event counter. Executes optionally a command if  an  event
              command has been executed before.

       -p     Writes data also to stdout (for piped logging).

       -u <name>
              Become another user, e.g. www-data.

       <command string>
              Defines  the  event command string where $0-$9 are substituted by the submatches of
              the regular expression.

EXAMPLE

       Executes the deny.sh script providing the IP address of the client causing a  mod_qos(031)
       messages whenever the log message appears 10 times within at most one minute:
         ErrorLog  "|qsexec  -e  \'mod_qos\(031\).*, c=([0-9a-zA-Z:.]*)\' -t 10:60 \'/bin/deny.sh
       $1\'"
