/*

* this script find some shell like

* c99, c100, r57, erne, Safe_Over

* 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 )
