sed: 1: "...": command c expects \ followed by text
sed: 1: "...": command i expects \ followed by text

# 查询一下
which sed

brew install gnu-sed

# 查看
brew info gnu-sed

Conflicts with:
  ssed (because both install share/info/sed.info)
Installed

==> 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="/opt/homebrew/opt/gnu-sed/libexec/gnubin:$PATH"

# 记得验证一下
which sed

# 当然你也可以直接使用 `gsed`
