Pesquisando nos Grupos do Yahoo

Meu amigo MrBits me deu essa grande ideia:

#!/bin/bash
QTDE=20
CHARSET=UTF-8
GROUP=shell-script

while getopts g:c:q: OPTION ; do
        case $OPTION in
        g) GROUP=$OPTARG ;;
        c) CHARSET=$OPTARG ;;
        q) QTDE=$OPTARG ;;
        esac
done

shift $(($OPTIND -1))

SEARCH="$@"

if [ -z "$SEARCH" ]; then 
        echo "Usage: $(basename $0) [-q qtde] [-g grupo] [-c charset] search" 
        exit 1
fi

BASEURL="http://br.groups.yahoo.com/group"
URL="${BASEURL}/${GROUP}/msearch?submit=OK&charset=${CHARSET}&cnt=${QTDE}&query=${SEARCH// /+}"  
SEDCMD="/message/!d;/${GROUP}/!d;/.*[0-9]/!d;s#/group#${BASEURL}#g;s/<[^>]*span>//g;s/$/<br \/>/"

LYNXOPT="-dump -force_html -assume_charset=${CHARSET}"
lynx $LYNXOPT <(  curl -b /tmp/cookie$$ -sL "${URL}" |  sed "${SEDCMD}" )

Vejamos em uso:

$ ./find.sh              
Usage: find.sh [-q qtde] [-g grupo] [-c charset] search

$ ./find.sh -q 10 getopts # procurando por getopts limitando a 10 registros

Divertido, não? o default é procurar no grupo shell-script do yahoo, mas ele pode investigar em qualquer um.

Valeu Mr.Bits!!
