Introduction

This example demonstrate how to use yad --notification. There is two part of example - first one is a set of udev rules for automounting usb flash drives, and second one - script which watches for creating or deleting new mount points and show notification icon with menu for unmounting flash drives

Details

Additional software: * udev * inotify-tools

Udev rules usually placed in file /etc/udev/rules.d/11-auto-mount.rules

udev rules

``` KERNEL!="sd[a-z]*", GOTO="auto_mount_end" ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="auto_mount_end"

Set environment

ACTION=="add", IMPORT{program}="/sbin/blkid -o udev -p -s TYPE -s LABEL %N"

Global mount options

ACTION=="add", ENV{mount_options}="relatime,users,umask=0"

Filesystem specific options

ACTION=="add", ENV{ID_FS_TYPE}=="vfat", ENV{mount_options}="%E{mount_options},showexec" ACTION=="add", ENV{ID_FS_TYPE}=="ntfs", ENV{mount_options}="%E{mount_options},utf8"

Get mount point

use basename to correctly handle labels such as ../mnt/foo

ACTION=="add", ENV{ID_FS_LABEL}=="?", PROGRAM="/usr/bin/basename '%E{ID_FS_LABEL}'", ENV{dir_name}="%c" ACTION=="add", ENV{dir_name}!="?", ENV{dir_name}="usbhd-%k"

Main action

ACTION=="add", ENV{dir_name}=="?", RUN+="/bin/mkdir -p '/mnt/usb/%E{dir_name}'", RUN+="/bin/mount -o %E{mount_options} /dev/%k '/mnt/usb/%E{dir_name}'" ACTION=="remove", ENV{dir_name}=="?", RUN+="/bin/umount -l '/mnt/usb/%E{dir_name}'", RUN+="/bin/rmdir '/mnt/usb/%E{dir_name}'"

LABEL="auto_mount_end"

label must be cleared

ENV{ID_FS_LABEL}="" ```

notification script

```
