Are you using Akubra?
Here's a script I wrote to match a PID and datastream to an Akubra
storage location.
#=======================================================================#
# getDatastreamPath.sh <fedora object pid>
# Get the path where Akubra has stored a datastream
# Scott Prater
# October 2010
#=======================================================================#
#=======================================================================#
# Configuration
#=======================================================================#
# Object root directory, as defined in akubra-llstore.xml
dsroot='/path/to/datastreams/root'
# The awk print string matches the directory pattern defined in
akubra-llstore.xml (ours is #/##/##)
awkcmd='{ print substr($0,1,1) "/" substr($0,2,2) "/" substr($0,4,2); }'
#=======================================================================#
# Main
#=======================================================================#
if [ "X$1" == "X" ]
then
echo "Usage: $0 <fedora_object_pid-datastream>" 1>&2
exit 1
fi
pid="$1"
path=`echo -n "info:fedora/$pid" | md5sum | awk "$awkcmd"`
fmtpid=`echo -n "info:fedora/$pid" | sed 's/:/%3A/g' | sed 's#/#%2F#g'`
ls -l "$dsroot/$path/$fmtpid"
