Usando um script que usa Duplicity + S3 excluindo arquivos grandes

Question

Estou tentando escrever um script de backup que excluirá arquivos de um determinado tamanho.

Se eu executar a duplicidade do script, aparece um erro. No entanto, se eu copiar e colar o mesmo comando gerado pelo script, tudo funcionará ...

Aqui está o script

#!/bin/bash
# Export some ENV variables so you don't have to type anything
export AWS_ACCESS_KEY_ID="accesskey"
export AWS_SECRET_ACCESS_KEY="secretaccesskey"
export PASSPHRASE="password"

SOURCE=/home/
DEST=s3+http://s3bucket

GPG_KEY="gpgkey"

# exclude files over 100MB
exclude ()
{
 find /home/jason -size +100M \
 | while read FILE; do 
  echo -n " --exclude "
  echo -n \'**${FILE##/*/}\' | sed 's/\ /\ /g' #Replace whitespace with "\ "
 done
}

echo "Using Command"
echo "duplicity --encrypt-key=$GPG_KEY --sign-key=$GPG_KEY 'exclude' $SOURCE $DEST"

duplicity --encrypt-key=$GPG_KEY --sign-key=$GPG_KEY 'exclude' $SOURCE $DEST

# Reset the ENV variables.
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export PASSPHRASE=

Quando o script é executado, recebo o erro;

Command line error: Expected 2 args, got 6

Onde estou errado?

Eu resolvi o problema ..

#!/bin/bash
# Export some ENV variables so you don't have to type anything
export AWS_ACCESS_KEY_ID="accesskey"
export AWS_SECRET_ACCESS_KEY="secretaccesskey"
export PASSPHRASE="password"

SOURCE=/home/
DEST=s3+http://s3bucket

GPG_KEY="gpgkey"

# Generate a filelist of excluded files over 100MB
find $SOURCE -size +100M > /tmp/filelist

duplicity --exclude-filelist /tmp/filelist --encrypt-key=$GPG_KEY --sign-key=$GPG_KEY $SOURCE $DEST

# Reset the ENV variables.
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export PASSPHRASE=
