Watch the progress of ‘dd’

Running this command will give you a idea on the progress of dd.

[email protected]:~$ dd if=/dev/urandom of=file.img bs=4KB& pid=$!

Running this code will execute dd in the background, and you’ll grab the process ID with ‘$!’ and assign it to the ‘pid’ variable. Now, you can watch the progress with the following:

[email protected]:~$ while true; do kill -USR1 $pid && sleep 1 && clear; done

The important thing to grasp here isn’t the filename or location of your input or output, or even the block size for that matter, but the fact that you can keep an eye on ‘dd’ as it’s running to see where you are at during its execution.

Using the Clip Utility with Vista & WS2008

Both Vista and Windows Server 2008 have a cool utility “CLIP” which you can use to pipe or redirect the contents from a command line to the clipboard.

For example:
ipconfig /all | clip
netstat -ant | clip
dir /s *.pdf | clip

You can also redirect the contents of a text file to the clip board with:

The clip utility can be handy for batch files or just gathering some details quickly and pasting them into a document.
