* and try to find some of unknow shell searching specific words this can be
* not safe
*
* how to use:
* the script don't need no-one of these parameter thay are facoltative
* -e Y/N enable disable eusristic mode (default is enable)
* -p a number 1-100 , it's the percentual of word that must be find into the file to warm the euristic mode
* -f check a single file
* -d check a single dir (normaly the program is recursive chek ALL file )
