Hi, community,
I created a script to send me a notification once the file transfer is done. I created a cron job from the service account to copy files from one server to another server using rsync command. The transfer part is working fine. However, I would like to get a notification once the transfer is completed. I couldn't think of a better logic so I created an additional file where the script adds 1 or 0. The reason I add that logic is that I am adding a script in a cron job to run from 4 am to 4 pm so I don't want to get false emails. For some reason, it's not sending me notifications and I don't know why. Does anyone have an idea why it's not working?

Code: #!/bin/bash
pid=$(sudo ps aux | grep "/bin/bash rsync" | grep -v grep)
EMAILS="email@email.com"
if [ "$pid" == "" ]
then
        echo "rsync is not running ..."
        checkRsync=`cat /root/scripts/rsync.out`
if [ "$checkRsync" == "1" ]
then
                echo "0" > /root/scripts/rsync.out
                               
                echo "Files have been copied to the production server successfully." | mail -s "Files Transfer completed" $EMAILS
        if [ $? -eq 0 ]
then
                        echo "--> E-mail Notification sent successfully ..."
                else
                        echo "--> FAILED to send notification ..."
                fi
        else
                echo "Files have already been copied to the production server."
                echo "0" > /root/scripts/rsync.out
        fi
else
echo "=> File transfer is still in the process ..."
        echo "1" > /root/scripts/rsync.out
fi
exit 0
Thank for your help.

There seems to be bug in dbus-1.14.4-x86_64-1.txz

Been having a strange problem with thunar in xfce on slackware64-current.

The view settings would inexplicably reset to "factory default".

Set it to view hidden files, turn off the side pane, full date format, list view.

The next time thunar is pulled-up, hidden files are not showing,
side pane is on, back to icon view, date format is back to 'today/yesterday'
when switching to list view.

Simply reverting to dbus-1.12.20-x86_64-5.txz grabbed from slackware64-15.0
cured the problem and the view settings now stay where they've been set.

There might be other settings that are also not 'sticking' in addition to
what I've seen in thunar.

The Huawei E3372 is a USB cellular network modem.
It is called a dongle and should connect to a USB 3.x port.
When you buy an E3372, get a new one or an unlocked used one. The E3372 box should contain the dongle and two ariels.
The E3372 needs an internet SIM. In the UK, a good choice is GiffGaff. Buy a new SIM (never a used one) and then choose your method of payment, contract or Pay As You Go. A contract has the usual contract terms and monthly payment method. A Pay As You Go method requires a monthly top-up which can be paid online by card or by using an ordinary GiffGaff top-up voucher. Check with GiffGaff for payment methods. The basic difference is that a contract will be better value but PAYG protects your privacy if you use vouchers.
You must register the SIM online with an email address.
Put the internet SIM in the dongle.
Fit the two ariels in the sockets on the side.
Connect the dongle to the compuer USB port, perhaps with a USB extension cable.
Then go through the Initial configuration below.
The following steps are based on Linux Mint 19.1, Cinnamon 4.0.10, Ubuntu 18.04.1. If you have an older version, maybe now is a good time to save everything on a big hard drive and update to Mint 19.1 or newer. (You can use that drive with a newer Linux.)
The dongle has drivers in firm ware that configure the dongle every time it starts. You need to ensure that the dongle is not trying to access the internet before the computer boot sequence completes.
Click menu > Preferences > Network: the dongle should be listed as USB Ethernet.
If there are any other network devices, you need to disable them before setting the E3372.
Click menu > Preferences > Network Connections > select the option for the dongle in the Ethernet list
> click on the Settings cog icon.
Click General tab > deselect Automatically connect to this network when it is available.
Click Ethernet tab. You should see a Device entry for the dongle. Cloned MAC address: might be the same entry.
> MTU: automatic
> Wake on LAN: select Default.
> Link negotiation: Ignore.
Click DCB tab > deselect Use Data Center Bridging (DCB) for this connection. (Unless you have a good reason to use DCB.)
Click Proxy tab > Method None (or Automatic)
> deselect For browser only.
Click IPv4 settings tab > Method Automatic (DHCP). All other fields should be blank.
Click IPv6 settings tab > Method Automatic, DHCP only. All other fields should be blank.
Click Save.
End of Initial Configuration. Reboot.
Normal Use of the dongle.
When you start the computer, you must wait until all the boot configuration completes before you turn on the dongle. At the bottom right of your screen in the panel, click on the network icon. In the pop-up menu, click on the button for HUAWEI MOBILE for a green tick.
To check the signal, click menu > Administration > System Monitor > Resources. If Network History shows activity then everything works. If there is no activity, leave the window open and watch it for a few minutes as your signal might be a problem.
The speed of the dongle will depend on how hot it gets, so put it in front of a fan !!

Running latest Arch

I ran "ddrescue --force -n /dev/sdX /dev/sdY rescue.map" as described in the Arch wiki on how to use ddrescue
https://wiki.archlinux.org/title/disk_cloning
and probably about 5-10 minutes later I read on my phone that ddrescue OVERWRITES the destination drive so I immediately ran as fast as I could to stop ddrescue from destroying more.
Now im left with an unusable 1TB drive (the one I was cloning) and also an unusable 4TB drive (the destination drive)
Both are NTFS drives. 4TB drive now shows up as "unallocated", cant be mounted and testdisk found 0 partitions.
I did run WxHexEditor and open the drive and to my surprise there is still a big amount of data intact. This drive probably has around 400~ GB of data on it but I dont think there is that much left now.

Is there any chance of me "rebuilding" the filesystem? slim chance but I just have to ask.
I could just reformat it bcs it is mostly 400GB of games from Steam but there is still alot of Assetto Corsa mods that I would lose if I did that.

I feel my best bet is to run a data recovery program now no?
Get the few personal files and the Assetto mods off and then reformat?
Worst case scenario maybe I can directly copy files via WxHexEditor by finding the start and the ends of files? idk thats probably waaay to tedious to spend any time on.
Quite ironic how I was going to clone a failing drive and ended up failing another drive :(
