Hello!

Im using sfdisk from util-linux 2.37.2
Running into issues with my old script.

sudo sfdisk HDD.img << EOF
label:gpt
,16M,4,*
,64M,U,*
,64M,L,
,1000M,L,
,,L,
EOF

It does not like the ,16M,4,* and the stated 4 to create a BIOS partition. I get output
HDD.img1: Failed to add #1 partition: Invalid command.

How do I use digits in this new version? Another synax?

Thanks

"4" is just the offset in the list of partition types, it does not seem to work for GPT tables.
To be safe use the type UUID:

label:gpt
,16M,21686148-6449-6E6F-744E-656564454649,*

You can also use sfdisk --dump on a manually formatted disk to get a starting point for a new sfdisk script.
