Simple BASH script to update subversion files

Question

This is just a simple BASH script that will update all .svn files in a specified directory.  If an update fails, it will attempt to update all the subdirectories in the failed one, so as much will be updated as possible.  Theoretically, you should be able to supply this script with only your root directory ( / ), and all the .svn files on your computer will be updated.

# Update the target directories
for target in ${dirs[@]}; do
    # If the target file contains a .svn file
    if [[ -d $target/.svn ]]; then
        # Update the target
        svn up $target || {
            # If the update fails, update each of its subdirectories
            for subdir in $( ls $target ); do
                [[ -d $target/$subdir ]] &&
                    ( svnup $target/$subdir )
            done
    # If the target file doesn't contain a .svn file
    else
        # Update each of its subdirectories
        for subdir in $( ls $target ); do
            [[ -d $target/$subdir ]] &&
                ( svnup $target/$subdir )
        done;
    fi
done

To filter out blank lines, you could just modify the awk command:
${exec awk '!/^$/ { print "-", $_ }' stuffigottado.txt}
very nice; awk and grep: two commands that never cease to amaze me.
