cdd.sh - "Chatty" dd

A short shell script that'll dd your data, and tell you how it's getting on the whole time.

Tested on Linux, but should run fine on Mac OS, BSD, and Cygwin too.

How do I use this?

• It's very easy. Start by grabbing a copy of the repo:

[email protected]:L0C4RD/cdd.git

• Then navigate to the directory you've cloned the repo into.
• Once you've done that, you can kick it off like so:

cdd.sh 0.5 if=/my/input/file of=/my/output/file

• The command is pretty much the same as regular old dd, but with a first argument which tells the script how often you'd like it to give you a progress report (in seconds.)

Why did you make this?

One of the most common questions I get asked is "how long is that dd going to take?" I wrote this script so that I'd be able to answer that question. It's not going to change the world, but it's kind of helpful.

Doing big convert-and-copy operations can take a long time. It can also be quite frustrating staring at an unchanging dd line in a terminal for hours on end, without any idea of its progress, so hopefully this will make someone's day a bit less rubbish.

Could you make this run on $OPERATING_SYSTEM ?

Probably. If you want to use it somewhere else, it should be pretty easy to tweak - and if not, just leave a message, and we'll do what we can.

Thanks, this is kind of handy!
