shell script (novamente)

[Paulo Górgias <gorgias@click21.com.br>]

pessoal segue o script que uso para fazer backup, como eu falei se eu executo
ele diretamente (./backup) ele funciona beleza, mas quando eu coloco para rodar
no cron só executa não executa o mysqldump todo o restante funciona mas
mysqldump não, alguem pode me ajudar:


script:

#!/bin/bash
# Shell script to backup MySql database
# To backup Nysql databases file to /backup dir and later pick up by your
# script. You can skip few databases from backup too.
# For more info please see (Installation info):
