Question

我从Fish Shell转到Zsh。

我刚刚经历了将一堆Fish函数转换为Zsh的漫长过程，大多数事情都有效，但我注意到当我输入ls时，它不仅没有工作，但实际上结束了终端标签会话：

➜  ~  cd code
➜  code  ls

[Process completed]

超级困惑，因为我没有（我不这么认为）做任何事情来搞乱这个命令。大多数其他基本命令似乎工作正常。什么可能导致这个混乱的想法？我已将新的Zsh功能和我的.zshrc文件放在下面。

这些函数主要是一堆Git / Zeus（一个Rails工具），它可以让我的生活更轻松：

可能不相关，但也让我感到困惑。当我打开与该文件中grep的使用相关的新shell选项卡时，我收到此警告。这与Fish之前没有发生过：

usage: grep [-abcDEFGHhIiJLlmnOoqRSsUVvwxZ] [-A num] [-B num] [-C[num]]
  [-e pattern] [-f file] [--binary-files=value] [--color=when]
  [--context[=num]] [--directories=action] [--label] [--line-buffered]
  [--null] [pattern] [file ...]

最后，导入这些插件的.zshrc文件。 This answer（尽管行为不同）表明它可能是PATH定义问题，但我认为我在PATH中包含了所有必要的路径：

# Path to your oh-my-zsh installation.
export ZSH=$HOME/.oh-my-zsh

export code_directory=$HOME/code/

ZSH_THEME="robbyrussell"

plugins=(functions github)

# User configuration

export PATH="/Users/sasha/.rvm/gems/ruby-2.2.0/bin:/Users/sasha/.rvm/gems/ruby-2.2.0@global/bin:/Users/sasha/.rvm/rubies/ruby-2.2.0/bin:/Users/sasha/.rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin"
# export MANPATH="/usr/local/man:$MANPATH"

source $ZSH/oh-my-zsh.sh

回答以下问题：

➜  .oh-my-zsh git:(master) ✗ which ls
ls: aliased to ls -G
➜  .oh-my-zsh git:(master) ✗ typeset -f ls
ls () {
    ls -G -lh $@
}
➜  .oh-my-zsh git:(master) ✗ type ls
ls is an alias for ls -G

更新

我已经找出导致它的，但为什么。这就是这条线：

ll () ls -lh $@

在我的函数文件中。我想当我输入ls -lh whatever-arguments-follow时会运行ll。当我跑ls时，有什么想法可能会引起错误？

Answer 1

好的，所以ls既是别名又是函数。这不会起作用，因为他们会逃避。在我的终端上，当我运行

时，ls是别名和功能

ls

它认为两秒钟，然后我得到了

ls:1: maximum nested function level reached

使用函数或别名，但不能同时使用两者。

编辑哦，看起来可行，但问题是ls函数是递归的。它应该读

ls () {
    command ls -G -lh $@
}

command内置版确保您执行实际命令，既不是别名也不是函数。

切换到zsh shell - `ls`结束终端选项卡
