第一种:

emptydir.sh

echo "$DIRECTORY is not empty"

fi

-----------------------------------------------------------

第二种:

count.sh

-----------------------------------------------------------

#!/bin/sh

count=`ls $*|wc -w`

if [ "$count" > "0" ];

echo "file size $count"

echo "empty!"

fi

-----------------------------------------------------------

#目录是否存在

ifmkdir.sh
