I thought that it would erase the file only if it had something to
write. It seems that it erases then checks to see if there is
something to write.
In any event my problem is solve I think. I wrote a small "C" program
that takes its input from amcheck. If it sees the word ERROR or
WARNING, it will return a value of 10. If amcheck works, it will
return a value of 0. So, my script looks like this:
su -c "amcheck amachine1 | backup_test" operator && su -c "amdump
machine1" operator
If backup_test returns a "0", it will do the dump.
