USBFlash

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}=""
