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=([0-9.]*)' -t 10:60 '/bin/deny.sh $1'"
