Mount - umount Sway kompozitorral

Waybar config ide vonatkozó részlete:

 "custom/unmount": {
        "exec": "~/.config/waybar/modules/unmount.sh check",
        "return-type": "json",
        "interval": "once", // Erre változik a megadott másodperc polling helyett
        "signal": 10,       // A kívánt szignál száma
        "format": "{icon}",
        "on-click": "~/.config/waybar/modules/unmount.sh",
        "format-icons": {
            "none": "",
            "many": "",
            "default": ""
        },
        "tooltip": true,
    },
 

Umount script a waybarhoz (~/.config/waybar/modules/umount.sh):

#!/usr/bin/env bash

entries=$(lsblk -Jo NAME,FSTYPE,SIZE,TYPE,MOUNTPOINT | jq -r '.blockdevices[] | select(.name != "sda") as $dev | $dev.children[]? | select(.mountpoint | type == "string") as $mp | [ $mp.name, $mp.mountpoint ] | @tsv')
count=$(echo -e "$entries" | grep -c '.')

if [ -z $1 ] && [ $count -gt 0 ]; then
    selected=$(echo -e "$entries"| wofi --dmenu -H 200 -W 240 -n -p "  Unmount devices" -D "hide_search=true" --cache-file /dev/null | cut -f 1)

    if [ ! -z $selected ]; then
        sudo systemctl stop usb-mount@$selected.service
#        notify-send "Mounting" "Umount /dev/$selected device"
        pkill -SIGRTMIN+10 waybar
    fi
fi

if [[ "$count" -gt 0 ]]; then
    class="many"
else
    class="none"
fi

printf '{"text":"%d", "class":"%s", "alt":"%s", "tooltip":"%d mounted"}\n' "$count" "$class" "$class" "$count"

Látható, hogy umount után kap szignált a waybar róla, hogy valami történt, frissíteni kell.

Természetesen van még egy systemd script és egy udev script is a teljesség igénye miatt.

Systemd script (/etc/systemd/system/usb-mount@.service):

[Unit]
Description=Mount USB Drive on %i

[Service]
Type=oneshot
RemainAfterExit=true
ExecStart=/usr/local/bin/usb-mount.sh add %i
ExecStop=/usr/local/bin/usb-mount.sh remove %i

Udev script a felcsatoláshoz (/etc/udev/rules.d/99_local.rules):

KERNEL=="sd[a-z][0-9]", SUBSYSTEMS=="usb", ACTION=="add", RUN+="/bin/systemctl start usb-mount@%k.service"
KERNEL=="sd[a-z][0-9]", SUBSYSTEMS=="usb", ACTION=="remove", RUN+="/bin/systemctl stop usb-mount@%k.service"
KERNEL=="mmcblk[0-9]p[0-9]", SUBSYSTEMS=="block", ACTION=="add", RUN+="/bin/systemctl start usb-mount@%k.service"
KERNEL=="mmcblk[0-9]p[0-9]", SUBSYSTEMS=="block", ACTION=="remove", RUN+="/bin/systemctl stop usb-mount@%k.service"

Csatoló script (/usr/local/bin/usb-mount.sh):
