dd comand :bs parameter unit
by E_BOURSEAU from LinuxQuestions.org on (#57DN0)
Hello
I'm trying to duplicate a whole disk in order to be at ease to run tests. Disk is 18 Gbyte large.
To achieve duplication, I use dd command.
Question is about dd parameter unit.
If I specify bs=512 does it mean it duplicates using block of 512 bytes or 512 K bytes ?
command run :
dd if=dev/rdsk/c0t0d0s2 of=/dev/rdsk/c0t9d0s2 bs=512 conv)noerror,sync
The server is equipped with 512 Mbyte of RAM and BUFSIZE is 1024.
Regards.
