The following shell function converts all of the symbolic links in a 
path into their "real" directories:


#
# remove all links
#
resolve_path() {
     declare path=$1
     declare l=`echo $path | sed -e 's;/; ;g'`

     declare rpath=

     for c in $l; do
         rpath=$rpath/$c
         while [ -h "$rpath" ] ; do
             ls=`ls -ld "$rpath"`
             link=`expr "$ls" : '.*-> \(.*\)$'`
             if expr "$link" : '/.*' > /dev/null; then
                 rpath="$link"
             else
                 rpath=`dirname "$rpath"`"/$link"
             fi
         done
     done

     echo $rpath
}

# ant is a symbolic link
path=/home/emberson/java/jakarta/ant/lib
echo $path

path=`resolve_path $path`
echo $path
# this echos "/home/emberson/java/jakarta/apache-ant-1.5.3-1/lib"
