In Ubuntu 16.04, I try to safely remove the flash disk from the command line. When I run the following script (from the Eject / safely remove vs umount):

udisksctl unmount -b /dev/sdb1 udisksctl power-off -b /dev/sdb1

It says:

Error powering off drive: Error opening /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/remove: No such file or directory (udisks-error-quark, 0)

When I type these commands from the keyboard, I don't get the error.

Why, and how should I make the script running?

The difference between the script and the manual typing might be a timing issue. If so, add a delay between the two commands.

udisksctl unmount -b /dev/sdb1 sync sleep 1 udisksctl power-off -b /dev/sdb1

    If the problem is timing, then && doesn't make any difference. The difference between ; (or newline, they're different ways of writing the same thing) and && is that with &&, the second command is executed only if the first succeeded. The timing of the commands is not affected. Commented Jun 14, 2017 at 23:24

  • ,@user31264 did you try the commands above with the sync and sleep? Commented Jun 16, 2017 at 3:43
