Although I considered asking this question in apple.stackexchange, my gut tells me the 'NIX crowd is more likely to produce a better response.
In what ways is the
dd (OS X version) command any different from UNIX (I use Ubuntu). I would like to duplicate an SD card with
dd as prescribed in the link with OS X.
An excerpt from the OS X
dd man page:
DESCRIPTION The dd utility copies the standard input to the standard output. Input data is read and written in 512-byte blocks. If input reads are short, input from multiple reads are aggregated to form the output block. When finished, dd displays the number of complete and partial input and output blocks and truncated input records to the standard error output.
