The path /usr/local/opt/binutils/bin should be added to your PATH environment variable.

You probably didn't notice the output from brew install binutils:

binutils is keg-only, which means it was not symlinked into /usr/local, because Apple's CLT provides the same tools.

If you need to have binutils first in your PATH, run: echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> /Users/ipellegrini/.bash_profile

For compilers to find binutils you may need to set: export LDFLAGS="-L/usr/local/opt/binutils/lib" export CPPFLAGS="-I/usr/local/opt/binutils/include"

So should be enough to:

• ⤵️
  run echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> ~/.bash_profile in order to add the bin folder to PATH, automatically, every time you open a new command-line shell.
• 🔄
  close the current shell and open a new one, for triggering the .bash_profile and making the command available for use.
• 🔍
  run which readelf to ensure that your desired command is found & reachable

Enjoy 🎉

you need to update your $PATH to include the homebrew install location. you probably want to look at other places people have asked this question like:
