I edit script for backup:

#!/bin/sh
.. /etc/profile.d/CP.sh
cd /var/CPbackup/backups
echo | backup -d --file /var/CPbackup/backups/
scp fw_export pluto(a)172.29.198.23:/data/backup
exit 0

Can I exec the backup command without me being asked "Are you sure you
want to proceed?"
The command "echo |" not work !!!

Thanks

You would have to check the manual page for the 'backup' command (which
is not a Linux or UNIX standard command) to see if it has an appropriate
option - I can't imagine why it needs to ask you to proceed. Could this
be a variable that is set in the /etc/profile.d/CP.sh file?

>The command "echo |" not work !!!

At least two problems. First, the 'backup' command has to display the
stupid question, but where does it do this? 'cron' has no standard
terminal, so it _may_ be trying to send the question via email to the
person running this crontab. A solution to that is to redirect stdout
to a file or device, such as /dev/null.

Second problem - the 'echo |' command is going to echo a carriage
return

[compton ~]$ echo | hexdump
0000000 000a
0000001
[compton ~]$

into the pipe, but is the backup program expecting input when invoked?
In your original post you indicated that things worked from the command
line, but not from cron. Does the 'echo |' work at the command line?
If it does, you might try

echo | backup -d --file /var/CPbackup/backups/ &>/tmp/somefile

to see if it's the lack of output device for cron that is causing the
problem.
