Recursive Bash Function for `svn update`

I work with a pretty fair number of subversion repositories at my employer and am constantly updating each of them manually - which can be both time consuming when remembered at the time I do it, or potentially cause conflicts and be error prone if I forget to do it. So to save myself the trouble of forgetting I have written and crontab'ed this script:

#!/bin/bash
source ~/.bashrc

SVN_ROOT=~/svn

function svnUpOrTraverse {
  path=$1
  if [[ -d $path ]]
  then
    upOutput=$(svn up $path)
    if [[ $(echo $upOutput | grep 'Skipped') ]]
    then
      for d in $(find $path -maxdepth 1 | grep -v "$path\$")
      do
        svnUpOrTraverse $d
      done
   else
      echo "$path Updated":
      echo; 
    fi
  fi
}

svnUpOrTraverse $SVN_ROOT
