How to install gnu sed on Mac OS X and set it as the default

install-gnu-sed-on-mac-osx.sh

# Check which version of sed is used when you run the `sed` command
# The version that ships with Mac OS X is 
#   /usr/bin/sed
which sed

# Install gnu-sed using Homebrew
# The `--with-default-names` option configures `sed` to use gnu-sed
# Without that option, you'll need to type `gsed` to use gnu-sed
brew install --default-names gnu-sed 

# Verify which version of sed is used when you run the `sed` command
#  OK:  /usr/local/bin/sed
#  BAD: /usr/local/bin/gsed 
# If BAD, run `brew uninstall gnu-sed`, then reinstall with `--with-default-names`
which sed

As others have pointed out, --with-default-names has been deprecated Homebrew/brew#5731.

Just install gnu-sed without the --with-default-names option. Then run brew info gnu-sed and it will tell you what to add to your PATH to be able to use it as "sed"

brew info gnu-sed (snippet)
==> Caveats
GNU "sed" has been installed as "gsed".
If you need to use it as "sed", you can add a "gnubin" directory
to your PATH from your bashrc like:

    PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
