Setting all the ORACLE* in the script. When I run it manually as Oracle, it's fine, even if I haven't source oraenv. It's running as Oracle's cron job, and...

So, now I read oracle's email....
Right:
cron env is /bin/sh; and my backup script has #!/bin/bash as the first line, of course, so that's the shell environment.
/bin/sh: -c: line 1: syntax error near unexpected token `&'
/bin/sh: -c: line 1: `/home/oracle/dbbackup.sh >> /opt/oracle/backup/backup.log 2>>&1'
So it's a syntax error in the crontab entry... but *why*?
Ok, just went into Bourne, and it doesn't like 2>>&1. So, a simple question: won't it toast backup.log if I don't do that as an append - that is, if I do 2>&1, instead of 2>>&1?
