CLI command for powering off Flash-Drive "disk"

  • 772
#!/bin/bash
    
borg create /media/greg/flash-drive/borg::"$(date +%FT)" /home/greg/borg && umount -l /media/greg/flash-drive

I use the above script to make backups to a thumb-drive (flash drive). As you can see, I use umount at the end. Doing this however does not result in the "eject button" symbol disappearing in Nautilus, so I don't know with 100% certainty that the drive has been unmounted (based on visual inspection in Nautilus) before pulling the thumb-drive.

Is there a command that will unmount and power-off the drive, removing the "eject button" symbol within Nautilus so I have visual confirmation that the drive is unmounted and that there is no possible way that damage could occur to the data when i pull the thumb-drive?

command-line

  1. To have confirmation that de flash drive is unmounted you can use the command lsblk. That wil show you al te mounted drives in your system.

    Take the command && umount ... out of the script and try running umount manually on the command line. See if this make a difference.

    If positive you need to adjust your script. At first I would delete the && and type umount on a new line.

    Please note that all access to the flash drive must be closed before unmount can be performed.
