Thunar: quick way to unmount USB disks and storage

D.dave · 2021-01-24 17:05:50

Hi,
with the update of Thunar to 4.16, I discovered that the side pane (when set as "Shortcuts") has changed the order: previously I had, in such order:
Devices
Places
Network

Now:

Places
Devices
Network

I prefer have Devices on top, but I cannot figure out how and if is possible to change such order; can someone tell me, if possible, to change such order?

Thank you.

Unfortunately no, its not possible to change the order. Have a read through this bug report for the rationale for the change.

D.dave · 2021-01-24 18:21:39

OK, I see (I also found it on GitLab and voted for make it configurable: https://gitlab.xfce.org/xfce/thunar/-/issues/447)

The fact is that:

I have a lot of entries under "Places" and when I have to unmount/eject a device, I have to scroll down a lot.
For mount is not a problem: under "Computer" I just do a double click on the disk which I want to mount (or set thunar-volman to automount).

Well, so I'm looking at least to create a Custom action which appears only on mounted disk (USB storages).
I tried to create a custom action: 'udisksctl unmount -b %f' but I cannot figure out how to make it appears on mounted disks: in the options I have set it for directory, but, so, appears only on directories.

Do you have any idea/workaround for this? I lurked the forum a lot and I've seen that you are expert about bash scripting and not only about Xfce :-)

It doesn't look like UCA can address mount points. (have you looked at https://docs.xfce.org/panel-plugins/xfce4-mount-plugin.

D.dave · 2021-01-25 08:02:38

Thank you for the hint; have it in the panel is very practical.
However, while attempting to insert personal commands, I got "failet to unmount".

My commands for unmount:

sudo sync %d && sudo udisksctl unmount %d && sudo udiskctl power-off %d
Because: I wanto to sync, unmount and power off (power off acts like "eject" from thunar, am I right?)

Furthermore, also If I unmount the devices /from Thunar), in such plugin, the devices disappears and I cannot mount them again from this plugin.

EDIT:

udisksctl unmount -b %d && udisksctl power-off %d works, but the disks, in such case USB HDD, are only unmounted but aren't been ejected/powered off.

From a Terminal, these commands (in such order) properly works:
udisksctl unmount -b /dev/sdc1 #%d
udisksctl power-off -b /dev/sdc1 #%d

But such plugin doesn't run them sequentially...

I think I've found a solution thanks to bash scripting :-)

#!/bin/bash

listmounted=$(findmnt -o LABEL,SOURCE | grep "/dev" | tail -n +2)
echo "$listmounted" > /tmp/mounted_disk
mapfile -t array < "/tmp/mounted_disk"
#getblocknames=$(findmnt -o LABEL,SOURCE | grep -P "/dev" | awk '{print $NF}' | tail -n +2)

#echo "$listmounted"
#echo "$getblocknames"

choosedisk=$(yad --title="Unmount" --width 210 --height 180 \
--form --item-separator="," \
--field="Choose what unmount:":CB "${array[0]}","${array[1]}")

choosedisk=$(echo "$choosedisk" | tr -d "|" | sed 's:.* ::')
echo $choosedisk

udisksctl unmount -b $choosedisk; udisksctl power-off -b $choosedisk

I'll add such script in a launcher on the panel :-)

The only thing that I still not figured out is how to add more arrays if more disks are mounted; maybe I will add an

if

condition; how do you would achieve this?

Do you think is ok?

EDIT:

Now is:

listmounted=$(findmnt -o LABEL,SOURCE | grep "/dev" | tail -n +2)
echo "$listmounted" > /tmp/mounted_disk
mapfile -t array < "/tmp/mounted_disk"
#getblocknames=$(findmnt -o LABEL,SOURCE | grep -P "/dev" | awk '{print $NF}' | tail -n +2)
arraynumbers=$(wc -l /tmp/mounted_disk | awk '{ print $1 }')


if [ $arraynumbers == 1 ];
then
entrynumbers="${array[0]}"
fi

if [ $arraynumbers == 2 ];
then
entrynumbers="${array[0]},"${array[1]}""
fi

if [ $arraynumbers == 3 ];
then
entrynumbers="${array[0]}","${array[1]}","${array[2]}"
fi

#echo "$listmounted"
#echo "$getblocknames"

#echo -e ${array[*]}

choosedisk=$(yad --title="Unmount" --width 210 --height 180 \
--form --item-separator="," \
--field="Choose what unmount:":CB "$entrynumbers")

choosedisk=$(echo "$choosedisk" | tr -d "|" | sed 's:.* ::')
echo $choosedisk


#udisksctl unmount -b $choosedisk &
#sleep 6
#udisksctl power-off $choosedisk

udisksctl unmount -b $choosedisk; udisksctl power-off -b $choosedisk

And it works: It gave me the enties of mounted disks without empty strings.
But is absurd fill the script of these if conditions

if [ $arraynumbers == 3 ];

So I ended up with the following script, which automatically populate the available disks to unmount in the YAD's menu:

#!/bin/bash

listmounted=$(findmnt -o LABEL,SOURCE | grep "/dev" | tail -n +2)
echo "$listmounted" > /tmp/mounted_disk
disktounmount=$(cat /tmp/mounted_disk | cut -d/ -f1 | awk '{$1=$1};1' | awk '{ print "\""$0"\","}' | tr -d "\n")

choosedisk=$(yad --title="Unmount" --width 210 --height 180 \
--form --item-separator="," \
--field="Choose what unmount:":CB "$disktounmount")

choosedisk=$(cat /tmp/mounted_disk | grep "$choosedisk" | cut -d " " -f3 )
echo "$choosedisk"

blocktounmount=$(cat /tmp/mounted_disk | grep "$choosedisk" | cut -d " " -f3)


if [ -z "$blocktounmount" ];
then
exit 0
fi

udisksctl unmount -b "$blocktounmount"; sleep 4; udisksctl power-off -b "$blocktounmount"

And is working flawlessy; before unmount the disk and then power it off.
However I want to be sure that I'm doing it in the proper way (eg I inserted sleep 4 between unmount and poweroff; maybe I have to check when the disk has been effectively unmounted instead of rely on fixed time)

EDIT:

Also done this thanks to fuser:

currentaccess=$(fuser -m "$blocktounmount")

until [ -z $currentaccess ]; do
	echo "Something is accessing the disk: these are the PIDS:"
	procname=$(ps -p $currentaccess -o comm=)
	yad --width=250 \
	--image=/home/dave/Pictures/icons/warning-icon_56.png \
	--title "Close remaining processes" --text="Please, close these apps: $procname" --button='Is closed':1
	currentaccess=$(fuser -m /home/dave/mounts/servicedisk)
done

If something is opened on the disk, this warning will appear:

On the "disktounmount..." line, you should also trim off the last "," so you don't have an extra blank line in the list. This should do it:

disktounmount=$(cat /tmp/mounted_disk | cut -d/ -f1 | awk '{$1=$1};1' | awk '{ print "\""$0"\","}' | tr -d "\n" | sed 's/.$//')

Edit:
Also your first line:

listmounted=$(findmnt -o LABEL,SOURCE | grep "/dev" | tail -n +2)

...won't work if someone has more than one hard drive.

Good points, ToZ!
Thank you!

Anyway: can you edit the title of this discussion? Now is no longer about Thunar, or at least "Devices above Places" :-)

ToZ · 2021-01-25 19:49:34

You can edit the title. Just edit your first post and make the change.

D.dave · 2021-01-25 21:20:57

I made a quick GIF recording to shows how such method is so much better and quicker :-)

ToZ · 2021-01-25 23:04:07

Nice. Can you post back your final code?

D.dave · 2021-01-25 23:11:41

Sure.
And also many thanks to you for your assistance.

I forget to say: obviously feel free to give me more suggestions, if in you opinions something is wrong or if could be improved :-)
