pg_archivecleanup standalone bash script

Hi all,

I want to hold the wal_files for 30 days on my slaves.
For that reason, I created a script to do that:

*pg_archivecleaup_mv.bash:*

#!/bin/bash -eu

declare -r -x PATH='/usr/local/bin:/usr/bin:/bin';

# We just wanna delete the wal_files older than 30 days

ARCHIVEDIR='/var/lib/pgsql/9.2/archive/'

CHKPOINT=$(find $ARCHIVEDIR -type f -mtime +30 -name '00*' -printf '%f\n' |
sort -r | head -1)

cd $ARCHIVEDIR

/usr/pgsql-${PG_VERSION}/bin/pg_archivecleanup $ARCHIVEDIR $CHKPOINT

find $ARCHIVEDIR -type f -mtime +30 -a -name '00*' -a ! -newer $CHKPOINT
-delete

*recovery.conf:*

archive_cleanup_command = 'exec nice -n 19 ionice -c 2 -n 7
../../bin/pg_archivecleaup_mv.bash -d /var/lib/pgsql/9.2/archive "%r"'

*PROBLEM:*

I'm getting an error message:

> pg_archivecleanup: must specify restartfilename
> Try "pg_archivecleanup --help" for more information.
> archive_cleanup_command "exec nice -n 19 ionice -c 2 -n 7
> ../../bin/pg_archivecleaup_mv.bash -d "../archive" "%r"": return code 512

And I can't figure out what is wrong....

Please, do you guys can help?
Cheers;
Patrick
