Hi,

There are several ways:

1) Use the tee command to direct output to a file

dd if=xxxxx of=xxxxx | tee dd_out.txt

2) Use the script command ahead of dd to capture the whole session

script dd_out.tst;dd if=xxxx of=xxxx

3) Or just redirect standard out
dd if=xxxx of=xxxx > dd_out.txt

HTH,
Jeff
