usb unmount script for sun rays

as promised here comes part two of the usb scripts for sun ray ultrathin-clients. this is yet simpler but fancier than the mount script because it uses zenity to display the result of the unmounting operation.

  37. # LINK THE USB DEVICE AND OPEN FILE BROWSER

  39. linklocation=~/usb$usbdisk
  40. # try to eject the device
  41. /opt/SUNWut/bin/utdiskadm -r $usbdisk
  42. # check exit code of utdiskadm
  43. if [ "$?" -eq "0" ]; then
  44. # check if ~/usbdisk* exists
  45. if [ -e $linklocation ]; then
  46. # remove the link to /tmp/SUNWut/mnt/ *
  47. rm $linklocation
  48. fi
  49. if [ -e /usr/bin/zenity ]; then
  50. /usr/bin/zenity --info --title="USB UnMounting succeeded" --text="You can physically unmount the USB device now."
  51. fi
  52. exit 0
  53. else
  54. if [ -e /usr/bin/zenity ]; then
  55. /usr/bin/zenity --error --title="USB UnMounting failed" --text="Something went wrong while unmounting $usbdisk."
  56. else
  57. echo ERROR. USB UnMounting of $usbdisk failed!
  58. fi
  59. exit 1
  60. fi

so this is what you should get after executing the script:

Sun Ray USB Umount Dialog

of course there is an appropriate dialog if something fails.

by the way i have recognized that the scripts do work only if executed in a terminal. to make sure that it is run in a terminal use the checkbox in the starters' preferences dialog. to be true i don't know why this is necessary.

please let me know if you find some errors while using this script. i'ld love to know if it helps you in your sun ray environment. leaving a comment would be nice. thanks!
