Macのsed & awkはBSD UNIXの物が標準でインストールされています。ひょんな事からsed & awkを勉強しようと思い立った矢先、書籍やWebの情報はGNUブランドのsed & awkの情報が圧倒的に多いことが分かりました。MacでもGNUブランドのsed & awkを利用するための設定を備忘録にまとめておこうと思います。
2023/5/17 最新のGNU Sed, GNU AWKに対応した情報に更新しました．
sed
参考記事より、まずHomebrewでgsedをインストールします。
brew install gnu-sed
.bash_profileにPATHを書き込み、有効化します。
echo 'export PATH="(brew --prefix)/opt/gnu-sed/libexec/gnubin/:$PATH"' >> ~/.bash_profiile
source ~/.bash_profile
$ sed --version

sedと同様の方法で設定出来ます。
brew install gawk

echo 'export PATH=(brew --prefix)/opt/gawk/libexec/gnubin:$PATH' >> ~/.bash_profile
source ~/.bash_profile
$ awk --version
