Witam

taki skrypt:
#!/bin/sh
MODULE=nvidia
if [ "$MODULE" = "nvidia" ]; then
         CARD_MODEL=NV11

         echo $CARD_MODEL | if grep "NV11" >/dev/null; then
             MODULE=nv
             echo "OK, module: $MODULE"
         fi
         echo "OK, module: $MODULE"
         MODULE=testmod
         echo "OK, module: $MODULE"
fi
echo "OK, module: $MODULE"

a wynik:
OK, module: nv
OK, module: nvidia
OK, module: testmod
OK, module: testmod

To jak to jest z tym "przedefiniowywaniem" zmiennych w petlach if ?
Dlaczego druga linia wyniku to nvidia ? a czwarta to testmod ?
