zsh:来自awk printf的意外输出

Question

在bash中,我可以执行以下操作:

$ printf "foo\nbar\n" | awk '{printf "%s\n", $1}'
foo
bar

...但是在我做同样的zsh时,我得到了这个:

$ printf "foo\nbar\n" | awk '{printf "%s\n", $1}'
[m\n", printf}'foo
bar

我做错了什么？

你有没有机会使用oh-my-zsh？$()由于自动终端标题设置中的快速扩展,终端设置中存在一个错误,导致它在printf和date(以及子命令!)等命令中评估%-tags .

查看~/.oh-my-zsh/termsupport.sh并应用此更改:
