This is a sample backup script I used, it has already a lot of options. Feel free to make any modification you want. If you add some good enhancements, let me know I can put them here so everybody can profit from them.

SID : SID, comma separated list of databases or ALL for all databases (running)
BACKUP_TYPE : INCR, FULL, COLD or ARCH
COMPRESS : COMPRESS or NOCOMPRESS to compress or not the backup
PARALLEL : defines the number of channel to use
exemple backup full : rman_backup.sh db1 FULL COMPRESS 16
exemple backup arch : rman_backup.sh db1 ARCH NOCOMPRESS 2
