I am a VBird, puzzled with two shell programmes

drowsyboy

Today I want to write a shell to delete directory from some directoy.
Two programes are given:
first:
----------------------------------------------------
cd /root/tmp
for loopdir in `ls`
do
        if [ -d $loopdir ]
        then
                 rm -R $loopdir
        else
                echo "not a directory"
        fi
done
----------------------------------------------------

second:
----------------------------------------------------
cd /root/tmp
filename=`ls`
if [ -d ${filename[1]} ]
then
    rmdir $filename
else
    echo "not a directory"
fi
----------------------------------------------------

Two programes both can work well
I want to kown how do the both programes work?
Please give some advice
