Show whether a working copy needs commit/update

[GoogleCodeExporter]

In the list of working copies, add a tag so that I can see if there are files 
that needs updates. See my (quick and dirty) geektools script that does the 
same for me if I place my working copies in the specified directories below:

---
#!/bin/sh

parse_svn_status() {
    local REV=$(                # get svn revision number
        svn info "$1" 2>/dev/null | grep Revision | sed -e 's/Revision: //'
    )
    [ "$REV" ] || return        # stop now if not a working copy

    local STATUS=(              # create an array

        # svn status items (second column is always ' ', 'C', or 'M')
        $( svn st "$1" | grep '^[^ ][ CM]' | \

        # first column only, filter duplicates
        sed -Ee 's/^(.).*$/\1/' | awk 'x[$0]++ == 0' )
    )

    [ "$STATUS" ] || return

    echo "$1 (${STATUS[*]})"
}

alldirs() {
for file in *; do
    if [ -d "$file" ]; then
#   echo "Checking:" "$file"
    parse_svn_status "$file";
    fi
done
}

echo "Subversion Dirty Working Copies"
echo ""
echo "Research:"
echo "---------"
pushd /Users/msv/Documents/Research >>/dev/null
alldirs
echo ""
echo "Teaching:"
echo "---------"
pushd /Users/msv/Documents/Teaching >>/dev/null
alldirs
echo ""
pushd /Users/msv/Documents/ >>/dev/null
parse_svn_status "Personal"

popd >>/dev/null
popd >>/dev/null
popd >>/dev/null
