Resizing a partition

[bitsnpcs]

Hello.
How can I check the real sequence of the partitions on linux command line?

Regards

Is this the correct command showing the orders you wanted, its shows the tree structure, size labels and mount point ?

Code:

sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

or this command shows the order of partitions and the start and end numbers of the blocks used -

Code:

sudo fdisk -l

Update -

Hello,

I have just reread you post, the maximum number of primary partition is 4, it says on the Ubuntu link.
Of your, about 19 partitions, how many are primary ?
