  Heh, that was my first thought when I saw "echo >/dev/null", but
redirections are applied in the order they appear on the command line, and
so stdout gets redirected first to /dev/null, then the 1> redirects it again
to the file.  Try it, it really works:

dk AT mace ~/test> ls -lart
total 0
drwxrwxrwx+  13 dk       Domain U        0 Oct 29 10:43 ..
drwxr-xr-x+   2 dk       Domain U        0 Oct 29 10:43 .
dk AT mace ~/test> /bin/echo "Test" >/dev/null 1>TestAct.log
dk AT mace ~/test> ls -lart
total 1
drwxrwxrwx+  13 dk       Domain U        0 Oct 29 10:43 ..
-rw-r--r--    1 dk       Domain U        5 Oct 29 10:43 TestAct.log
drwxr-xr-x+   2 dk       Domain U        0 Oct 29 10:43 .
dk AT mace ~/test> cat TestAct.log
Test

  You forgot to mention cron-diagnose.sh!  I think 1.7 is the most recent.
