 Try --in-order command line option, the option is undocumented in old
 versions ;-(

 sfdisk --in-order -L -uM /dev/sdb <<-EOF
 1,10,83
 ,,83
 ;
 ;
 EOF

 result (output from fdisk):
       Device Boot      Start         End      Blocks   Id  System
    /dev/sdb1            2048       22527       10240   83  Linux
    /dev/sdb2           22528      204799       91136   83  Linux



sfdisk --in-order -L -uS /dev/sdb <<-EOF
