Command substitution in zsh

Question

I'm trying to use simple command substitution in zsh to cd to the output of another command ( which with dirname ).

• which git → /usr/bin/git as expected;
• dirname $(which git) → /usr/bin as expected;
• cd $(dirname $(which git)) → cd: no such file or directory: ^[[0m^[[0m/usr/bin

What's happening here? What is ^[[0m and why is it showing up all of a sudden?

删除~/.zshrc这一行~/.zshrc它：

trap 'printf "\\e[0m" "$_"' DEBUG
