Requirement
I want to write a file at various offsets into the partition.
Partition /dev/part2 is mounted at /mypart
I tried the commands below:
dd if=/dev/urandom of=/mypart/aaa bs=1024 seek=0 count=15000
dd if=/dev/urandom of=/mypart/aaa bs=1024 seek=15000 count=15000
dd if=/dev/urandom of=/mypart/aaa bs=1024 seek=30000 count=15000
Are they doing what I want to do? Are they writing a file to the partition at offset 0, 15000K and 30000K?
At what offset is the file written if I omit seek
from dd
?
dd if=/dev/urandom of=/mypart/aaa bs=1024 count=15000
