I’m trying to learn a bit about bash-commands — more specifically about backup-scripts.
Unfortunately, I get a syntax error on the last line. I have no idea what I’ve done wrong and would appreciate any feedback on this matter.

Code:

#!/bin/sh

if [ -f $"/archive/backup-20110111.tar.gz" ]; then
    echo "File already exists"
else
    sudo cp /home/plepple/Documents/backup/backup-20110111.tar.gz
            /home/plepple/Documents/backup/archive/backup-20110111.tar.gz
    rm /home/plepple/Documents/backup/backup-20110111.tar.gz
fi

if [ -f $"/archive/backup-20110112.tar.gz" ]; then
    echo "File already exists"
else
    sudo cp /home/plepple/Documents/backup/backup-20110112.tar.gz
            /home/plepple/Documents/backup/archive/backup-20110112.tar.gz
    rm /home/plepple/Documents/backup/backup-20110112.tar.gz
fi

curdate='date +%Y%m%d'
mv /home/plepple/Documents/backup/backup.tar.gz
   /home/plepple/Documents/backup/backup-$curdate.tar.gz

I tried to execute it (through bash) with:

bash backupscript.sh

All the files and directories exist.

Thanks!

    mv /home/plepple/Documents/backup/backup.tar.gz
   /home/plepple/Documents/backup/backup-$datum.tar.gz

    should be

    mv /home/plepple/Documents/backup/backup.tar.gz \
   /home/plepple/Documents/backup/backup-$datum.tar.gz

    The same goes for 

    sudo cp /home/plepple/Documents/backup/backup-20110111.tar.gz \
            /home/plepple/Documents/backup/archive/backup-20110111.tar.gz

    and

    sudo cp /home/plepple/Documents/backup/backup-20110112.tar.gz \
            /home/plepple/Documents/backup/archive/backup-20110112.tar.gz
