I wrote this quick shell script to loop over the file and do a recursive grep for that key. The key is considered “used” if it exists in the current directory with quotes around it (single or double). This WILL NOT find keys if they are only used programmatically. (e.g. VAR + “.started”)

#!/bin/sh

# Loops over all the keys in the given messages.properties file
# and looks in the current directory for the string in quotes.
# Results are printed to stdout
#
# use: (from the “web” dir in openmrs)
# sh ./findunusedmessages.sh WEB-INF/messages.properties

propfile=$1
props=`awk -F= ‘{print $1}’ $propfile`
count=0
total=0

echo “These property keys were not found in the code base:”
for prop in $props
do
#echo “Looking for property: $prop”
if [ ! -z "$prop" ];
then
total=`expr $total + 1`
output=`grep –exclude-dir=”.svn” -re “[\'\"]$prop[\'\"]” *`
if [ -z "$output" ];
then
echo “$prop”
count=`expr $count + 1`
fi
fi
done

echo “done! Found $count possibly uneeded message keys in $propfile (out of $total total keys)”

I ran this for a few hours to get through all rows. (Note that it overwrites any uuids that are currently there)

Copy this into a sql script and run it with “source” in mysql at command line.

drop procedure update_uuids;
delimiter //
create procedure update_uuids() begin
set @max = (select max(obs_id) from obs);
set @x = 1;
repeat
set @y = @x + 100000;
update obs set uuid = uuid() where obs_id >=@x and obs_id <@y;
set @x = @y;
until @x > @max
end repeat;
end
//
delimiter ;
call update_uuids();
