need help understanding mv
I just started shell coding and I'm a bit confused on how 'mv' works can someone explain to me how it works and if i did this correctly. Thanks.

Code:
echo "Enter Name of the first file:"
    read file1
    #echo $file1
    if [! -e $file1]; then
        echo "Sorry, file does not exist."
        exit 1
    fi

    echo "Name of the second file:"
    read file2

    if [! -e $file2]; then    
        echo "Sorry, file does not exist."
        exit 1
    else
        #echo $file1
        #echo $file2
        set tmp = $file1
        mv "$file2" "$file1"
        mv "$tmp" "$file2"
    fi;;

once it gets down to the 'mv' i get
Quote:
mv: cannot stat `file.txt': No such file or directory
which confuses me since both files pass the if statements. Can someone clarify?
