dd command

Ran a dd command to create a 10GB file on both Linux and AIX.
When issued top on Linux, saw only one process being used while on AIX in the ou
tput of topas, it was showing 2 lines for dd.
Does 2 lines in AIX's topas mean, AIX parallelizing the dd command operation?

yes, one dd command forks a child process
