What's the difference between readelf and eu-readelf?

Question

You get eu-readelf from:

$ sudo apt-get install elfutils

I was just wondering why you would use one over the other ?

Answer 1

On Linux, there are two implementations of readelf:

• readelf from GNU binutils
• eu-readelf from elfutils

The tools from elfutils were written to be smaller, faster, and more featureful than those in binutils.
