Modern coreutils has an utility named truncate - it can "truncate" afile to _larger_ size. So, provided you had image.raw of size N GB, and you want it to be N+M Gb, you use truncate --size $((N+M))G image.raw. _Much_ safer and simpler... ;) There are much much simpler ways exist.

Much faster way, using dd:

dd if=/dev/zero of=foo.img bs=1 count=1 seek=$(($(stat -c%s foo.img)+10*1024**3-1))

For the second way, I don't think this will work because enlarge it with /dev/zero (not null, i think).. and this not a valid partition.. Bye For Marius:

cat temp.img >> foo.img

Yes, you can do this, but this would delete the backup too ..

For the second way, I don’t think this will work because enlarge it with /dev/zero (not null, i think).. and this not a valid partition..

Can you do it even faster by enlarging the first file in-place with dd if=/dev/null of=foo.img bs=1b seek=20G count=0 (in this case the 20G is the new total size, not the increment!)? Can you do it faster by replacing the second step with

Can you do it even faster by enlarging the first file in-place with

dd if=/dev/null of=foo.img bs=1b seek=20G count=0

(in this case the 20G is the new total size, not the increment!)?
