fix-perms.sh

if [ -d "$1/sites" ]; then
        cur_dir=`pwd`
        echo $cur_dir
        cd $1
        echo `pwd`
        echo "chmod directories"
        find . -type d -exec chmod u=rwx,g=rx,o=rx {} \;
        echo "chmod files"
        find . -type f -exec chmod u=rw,g=r,o=r {} \;
        echo "chmod sites/default/files"
        chmod -R o+w sites/default/files
        echo "chmod for bam"
        chmod -R g+w sites/default/files/private/backup_migrate/
        cd $cur_dir
        echo `pwd`
else
        echo "give me a valid directory, man!"
