mai copii, de ce nu vreti voi sa cititi documentatia?
cu riscul de a ma repeta, va retrimit la pagina de manual a lui sfdisk:
-d Dump the partitions of a device in a format useful as input to
sfdisk. For example,
% sfdisk -d /dev/hda > hda.out
% sfdisk /dev/hda < hda.out
-x or --show-extended
Also list non-primary extended partitions on output, and expect
descriptors for them on input.
Create partitions
The fourth type of invocation: sfdisk device will cause sfdisk to read
the specification for the desired partitioning of device from its stan-
dard input, and then to change the partition tables on that disk. Thus,
it is possible to use sfdisk from a shell script. When sfdisk deter-
mines that its standard input is a terminal, it will be conversational;
otherwise it will abort on any error.
iar ceva mai jos:
INPUT FORMAT
sfdisk reads lines of the form
<start> <size> <id> <bootable> <c,h,s> <c,h,s>
where each line fills one partition descriptor.
sau pe scurt:
- sfdisk -d -> pt a crea un dump al tabelei de partitii (inclusiv
partitiile logice)
- sfdisk <device> < fisierul_de_la-d ->pt a recrea
fara dd, fara a va preocupa cit e de mare tabela, etcetc.
un exemplu de la mine:
root# sfdisk -d /dev/hde
# partition table of /dev/hde
unit: sectors
/dev/hde1 : start= 63, size= 64197, Id=83, bootable
/dev/hde2 : start= 64260, size= 30716280, Id=83
/dev/hde3 : start= 30780540, size= 1044225, Id=82
/dev/hde4 : start= 31824765, size= 85401540, Id= 5

/dev/hde6 : start= 32451363, size= 30732282, Id=83
