切换到 zsh shell -- `ls` 结束终端选项卡

Question

我正在从 Fish Shell 切换到 Zsh。

我刚刚经历了一个漫长的过程，将我的一堆 Fish 函数转换成 Zsh，大多数东西都在工作，但我只是注意到当我输入 ls 时，它不仅不起作用，但实际上结束了终端选项卡会话：

➜  ~  cd code
➜  code  ls

[Process completed]

超级令人费解，因为我没有（我不认为）做任何事情来扰乱该命令。大多数其他基本命令似乎都可以正常工作。有什么想法可能导致这种混乱吗？我把我的新 Zsh 函数和我的 .zshrc 文件放在下面。

函数，主要是一堆Git/Zeus（一个Rails工具）函数，让我的生活更轻松：

Probably unrelated, but also confusing to me. I get this warning when I open a new shell tab in relation to the uses of grep in that file. This didn't happen before with Fish:

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 ...]

最后是导入这些插件的.zshrc文件。 This answer（尽管行为不同）表明它可能是 PATH 定义问题，但我认为我在我的 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

我已经弄清楚 是什么 导致了它，但不知道 为什么 。就是这一行：

ll () ls -lh $@

在我的函数文件中。当我输入 ll 时，我认为会运行 ls -lh whatever-arguments-follow。任何想法为什么当我运行 ls?

时会引发错误

Answer 1

好的，所以 ls 既是别名又是函数。那是行不通的，因为它们会递归。在我的终端上，当我运行

时，ls 是一个别名和一个函数

ls

它想了两秒钟，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。

Edit 哦，看起来可以，但问题是 ls 函数是递归的。应该是

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

command 内置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
