Script to mount drive - `mount-menu.sh`

The mount-menu.sh script allows you to select unmounted drives/partitions for mounting. To call the script use: sudo mount-menu.sh. This screen appears tailored to your unique machine environment:

Use arrow keys to select the partition and press Enter

The menu clears and leaves this information in your terminal:

=====================================================================
Mount Device:  /dev/nvme0n1p10
Mount Name:    /mnt/mount-menu.FPRAW
File System:   ext4
ID:            Ubuntu
RELEASE:       18.04
CODENAME:      bionic
DESCRIPTION:   Ubuntu 18.04.1 LTS
 Size  Used Avail Use%
  27G  7.9G   18G  32%

Now you can use: cd /mnt/mount-menu.FPRAW to access your external drive’s partition.

Then you can use cd home/YOUR_NAME being mindful not to put a / in front of home. Should you use cd /home it would take you to your boot drive and out of the external drive.
