Hi Sam,

Here is my script. I don't know which OS are you using?

$ cat /u01/scripts/cleanup_rman_arch_test2.sh
#!/bin/ksh
ORACLE_SID=TEST2; export ORACLE_SID
ORACLE_HOME=/u01/oracle8i/product/8.1.7; export ORACLE_HOME
PATH=$ORACLE_HOME/bin; export PATH
$ORACLE_HOME/bin/rman target username/password@TEST2 catalog rman/rman@rcat log=/u01/logs/cleanup_rman_arch_test2_log @/u01/scripts/cleanup_rman_arch_test2.rcv
exit

$ cat /u01/scripts/cleanup_rman_arch_test2.rcv
allocate channel for delete type disk;
change archivelog until time 'SYSDATE-7' delete;
release channel;

Cheers!
Farrukh
