if you omit bs, dd chooses some default size, if you omit both, dd just keeps on writing til the disk is full. if the input file is endless, like /dev/null.

this is not specific to dd anymore and you really have to tell us what you're talking about.
my system does not have an "edquota" command.
what are you trying to test/achieve, on what system?
please read the first link in my signature.
