But it doesn't work, its asking for amanda's pw and there isn't one.
Here is what I did:
root@coyote:~$ su amanda
amanda@coyote:/root$ echo $Cmdresume
amanda@coyote:/root$ Cmdresume="/opt/trinity/bin/dcop kmail KMailIface
resumeBackgroundJobs"
amanda@coyote:/root$ echo $Cmdresume
/opt/trinity/bin/dcop kmail KMailIface resumeBackgroundJobs
amanda@coyote:/root$ sudo -H -u gene bash -c $Cmdresume
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
[sudo] password for amanda:
Sorry, try again.
[sudo] password for amanda:
So I'll just do it from my own crontab, holding the background stuff
for an hour 31 while amanda is running.
Like this:
59 1 * * * /opt/trinity/bin/dcop kmail KMailIface pauseBackgroundJobs
30 3 * * * /opt/trinity/bin/dcop kmail KMailIface resumeBackgroundJobs
And we'll see if that works.

That entry, previously shown in this thread was an sudoers killing syntax error, so its
been removed. thanks to having
more than one root session going at the time.

Well, that is sucky :(
For the display issues earlier, try one of these:
export DISPLAY=:0
export DISPLAY=:0.0
Under your username do:
echo $DISPLAY
and I’m guessing use that. Mine is “:0”, the :0.0 was used in a cron
entry itself*, so probably not the one to use.
This is from an old bash script I ran in root cron that needed to also
start something as myself. It was on a Ubuntu 14.04 box, it’s Debian
based but might not be the exact syntax anymore.
export DISPLAY=:0
sudo -H -u michael bash -c '/usr/bin/progname &'
As long as you have the right sudoers entry (it looked like you had
way overkill, but it should work), running the same in the amanda
script should work. On Saturday 19 December 2020 07:39:34 pm Gene

This second URL showed me how to edit the sudoers file and add
this:
amanda ALL=(ALL) NOPASSWD:/opt/trinity/bin/dcop
But it still fails:
root@coyote:~$ su amanda -c "/opt/trinity/bin/dcop --user gene
--all-sessions kmail KMailIface resumeBackgroundJobs"
sudo NOT su... Read the first link, they go together... AFIK,
you'll need to reformat the whole command for sudo (as it is not
the same format as su).
Don't run as root either! Run it as plain amanda, even if you
have to stick it in a test script and add it to amanda cron to
kick it off. I’ll guess this should be the full syntax of the
lines you need:
export DISPLAY=:0
probably not needed, these scripts normally only send emails.
sudo -H -u gene bash -c '/opt/trinity/bin/dcop
kmail KMailIface
pauseBackgroundJobs'
how about, since the commands are already defined above it:
sudo -H -u gene bash -c "$Cmdholdit" ? etc. or "$Cmdresume" at the
end?
>do backup
stuff<<
sudo -H -u gene bash -c '/opt/trinity/bin/dcop kmail KMailIface
resumeBackgroundJobs'
HTH,
Michael
* Cron entry was like:
export DISPLAY=:0.0 ; /home/michael/common/bin/bashscript.sh
