Hi Leslie!

I believe this is what you need:

--- START ---
#!/bin/sh

KEEP='5'

pg_dump -U gp > /backups/gp.`date +%Y%m%d-%H%M%S`.sql

N=1
for file in `ls -r /backups/gp.*`
do
       [ $N -gt $KEEP ] && rm -f $file
       N=`expr $N + 1`
done
--- END ---

I am using this to keep 5 backup files... Modify as needed.

Cheers,
Miguel
