What does the bs do in the command dd do?
 

Hello,

I have just created a usb boot disk so that I can install Fedora 14.

I used the following which was successfully. However, I am left wondering what does the bs parameter actually does. I know it mean bytes and copies these at a time. But how do I know what to set it to?

In the above example it is set to 8MB. However could I set this to any value that I want?

Many thanks for any advice,

Hello ukwho,

the bs option tells dd which datasize it should move at a time (says the manpage). For further information look here: http://softpanorama.org/Tools/dd.shtml
