Remplacer:

basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')") 

par:

basedir=$(dirname $(echo "$0" | sed -e 's,\\,/,g')) 

Et:

echo \"$basedir\" should eq $(dirname "$(echo "$0" | sed -e 's,\\,/,g')") 
echo $(echo "$0" | sed -e 's,\\,/,g') 

par:

echo \"$basedir\" should eq $(dirname $(echo "$0" | sed -e 's,\\,/,g')) 
echo $(echo "$0" | sed -e 's,\\,/,g')
