shell - 尝试在 mac 上运行命令时出现 fish 错误

Question

我使用以下命令并安装了 fish

diff -y <(unzip -l old.zip) <(unzip -l new.zip)

我收到以下错误:

fish: Invalid redirection target: (unzip -l new.zip)
diff -y <(unzip -l new.zip) <(unzip -l old.zip)
        ^
fish: Invalid redirection target: (unzip -l old.zip)
diff -y <(unzip -l new.zip) <(unzip -l old.zip)

有解决方法吗？

Answer 1

<(a_command)语法是fish 不支持的bash'ism。为了与 fish 对显式命令而不是魔术语法的偏好保持一致，psub命令用于实现类似的效果:

diff -y (unzip -l new.zip | psub) (unzip -l old.zip | psub)
