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.
