  • 2 down vote

    If I remember correctly, dd is much more "low level" in is approach, skipping such fancy things as filesystems and all the bells and whistles :)

  • dd is problematic in the presence of disk errors, and can hang or more importantly ignore non readable data
  •  
    Fascinating discussion over at Stack Overflow.
    Elucidates some of the subtle differences between dd and cat, and when and why you might want to use one over the other.

khtml2png - Take Command Line Web Screenshots on Linux - 0 views

  •

It's nice to use because it will get the entire length of the site, no matter whether it is fully visible in the browser. And, it sure beats shell scripting Firefox to open on a different display and capturing an image with Imagemagick
