Useful when you want to know the mbrid of a device - for the purpose of making it bootable. Certain hybridiso distros, for eg the OpenSUSE live ISO uses the mbrid to find the live media. Use this command to find out the mbrid of your USB drive and then edit the /grub/mbrid file to match it.

Watch the progress of 'dd'

Only slightly different than previous commands. The benefit is that your "watch" should die when the dd command has completed. (Of course this would depend on /proc being available)

a fast way to repeat output a byte

the speed is about 500MB/s on my machine.

i think it's fast enough to output not too many bytes.

while a C program may output 1GB per sencond on my machine.

if the size is not the power of 512,you may change the bs and count in dd.

Create a 5 MB blank file via a seek hole

Similar to the original, but is much faster since it only needs to write the last byte as zero. A diff on testfile and testfile.seek will return that they are the same.

Start dd and show progress every X seconds

Adjust "sleep X" to your needs.

*NOTE: First sleep is required because bash doesn't have a "post-test" syntax (do XXX while).
