sgdisk Command Questions

[spflanze]

I am using sgdisk to partition SSD drives for ZFS, to be used for an Ubuntu installation.

How important is it there be a space between the option and its argument? In other words would these two commands be equivalent:

sgdisk     -n 1:1M:+512M   -t 1:EF00 $SSD1
sgdisk     -n1:1M:+512M   -t1:EF00 $SSD1

?

While assigning partition numbers with the -n option, is it necessary these numbers be incremented only by 1 every subsequent sgdisk command? Or is the order the numbers used to assign a partition unimportant? In other words would this command sequence:

sgdisk     -n 1:1M:+512M   -t 1:EF00 $SSD1
sgdisk     -n 2:0:+256G      -t 2:FD00 $SSD1
sgdisk     -n 3:0:+2G          -t 3:BE00 $SSD1

be as valid as this one:

sgdisk     -n 1:1M:+512M   -t 1:EF00 $SSD1
sgdisk     -n 3:0:+256G      -t 3:FD00 $SSD1
sgdisk     -n 2:0:+2G          -t 2:BE00 $SSD1

?

Can a partition number be skipped, and not used? Such as, for example, is this sequence valid:

sgdisk     -n 1:1M:+512M   -t 1:EF00 $SSD1
sgdisk     -n 2:0:+256G      -t 2:FD00 $SSD1
sgdisk     -n 4:0:+2G          -t 4:BE00 $SSD1

Where the number 3 is never used to create a partition with?

I my answers by testing. The answers:

The space between the option, and the argument, is optional. I does not have to be there. The command works as well with, and without, it.

The partition numbers can be assigned in any order. They need not increment by a value of one in every subsequent sgdisk command.
