NAME

       qsgrep - prints matching patterns within a file.

SYNOPSIS

       qsgrep -e <pattern> -o <sub string> [<path>]

DESCRIPTION

       qsgrep  is  a  simple tool to search patterns within files. It uses regular expressions to
       find patterns and prints the submatches within a pre-defined format string.

OPTIONS

       -e <pattern>
              Specifies the search pattern.

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

       <path> Defines  the  input  file to process. qsgrep reads from from standard input if this
              parameter is omitted.

EXAMPLE

       Shows the IP addresses of clients causing mod_qos(031) messages):

         qsgrep -e 'mod_qos\(031\).*, c=([a-zA-Z0-9:.]*)' -o 'ip=$1' error_log
