Debian under Windows 10: Mount/Umount

Debian GNU/Linux is available for Windows users through the Windows store as an app for the Windows Subsystem for Linux (WSL). That works quite nicely but, USB drives can be a bit annoying to use - there is no automatic mounting.

To facilitate mounting/unmounting these drives I wrote two BASH functions that take a device letter (it does not matter if you use uppercase or lowercase) as an argument.

• wmount mounts the drive (and generates a mount point if necessary).
• wumount unmounts the drive (and keeps the mount point for later use)

Maybe you have some use for these functions

wmount () {
  if [[ $# -ne 1 || ! ($1 =~ [a-zA-Z]) ]]; then
    echo Usage $0 [drive_letter]
    return 1
  fi

  drive_letter=$(echo $1|tr '[:lower:]' '[:upper:]')
  mount_dir="/mnt/$(echo $1|tr '[:upper:]' '[:lower:]')"

  if [[ ! -d $mount_dir ]]; then
    sudo mkdir $mount_dir
  fi

 sudo mount -t drvfs $drive_letter: $mount_dir
}

wumount () {
  if [[ $# -ne 1 || ! ($1 =~ [a-zA-Z]) ]]; then
    echo Usage $0 [drive_letter]
    return 1
  fi

  mount_dir="/mnt/$(echo $1|tr '[:upper:]' '[:lower:]')"
  if [[ -d $mount_dir ]]; then
    grep -qs "$mount_dir " /proc/mounts
    if [[ $? ]]; then
      sudo umount $mount_dir
    fi
  fi
}
