Zsh无法正确自动完成我的ssh命令。

Question

Zsh无法正确自动完成我的ssh命令。

17

我在ssh自动补全方面遇到了一些问题。我希望我的zsh能够在我的.ssh/config文件中实现自动补全，但直到现在它只在/etc/hosts文件中实现了自动补全。我找到了如何不使用hosts文件的方法，只需要添加以下配置

zstyle ':completion:*:ssh:*' hosts off

但是我无法成功让zsh查看.ssh/config文件，我已经试过了，但很遗憾它没有起作用。

zstyle ':completion:*:ssh:*' config on

这是我的.zshrc文件

    # If you come from bash you might have to change your $PATH.
    #export PATH=$HOME/bin:/usr/local/bin:/usr/local/sbin:~/Documents/workspace/flutter/bin:$PATH

    # Path to your oh-my-zsh installation.
    export ZSH=/Users/thoma/.oh-my-zsh

    # Set name of the theme to load. Optionally, if you set this to "random"
    # it'll load a random theme each time that oh-my-zsh is loaded.
    # See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
    ZSH_THEME="agnoster"

    # Set list of themes to load
    # Setting this variable when ZSH_THEME=random
    # cause zsh load theme from this variable instead of
    # looking in ~/.oh-my-zsh/themes/
    # An empty array have no effect
    # ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

    # Uncomment the following line to use case-sensitive completion.
    # CASE_SENSITIVE="true"

    # Uncomment the following line to use hyphen-insensitive completion. Case
    # sensitive completion must be off. _ and - will be interchangeable.
    # HYPHEN_INSENSITIVE="true"

    # Uncomment the following line to disable bi-weekly auto-update checks.
    # DISABLE_AUTO_UPDATE="true"

    # Uncomment the following line to change how often to auto-update (in days).
    # export UPDATE_ZSH_DAYS=13

    # Uncomment the following line to disable colors in ls.
    # DISABLE_LS_COLORS="true"

    # Uncomment the following line to disable auto-setting terminal title.
    # DISABLE_AUTO_TITLE="true"

    # Uncomment the following line to enable command auto-correction.
    # ENABLE_CORRECTION="true"

    # Uncomment the following line to display red dots whilst waiting for completion.
    # COMPLETION_WAITING_DOTS="true"

    # Uncomment the following line if you want to disable marking untracked files
    # under VCS as dirty. This makes repository status check for large repositories
    # much, much faster.
    # DISABLE_UNTRACKED_FILES_DIRTY="true"

    # Uncomment the following line if you want to change the command execution time
    # stamp shown in the history command output.
    # The optional three formats: "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
    # HIST_STAMPS="mm/dd/yyyy"

    # Would you like to use another custom folder than $ZSH/custom?
    # ZSH_CUSTOM=/path/to/new-custom-folder

    # Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
    # Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
    # Example format: plugins=(rails git textmate ruby lighthouse)
    # Add wisely, as too many plugins slow down shell startup.
    plugins=(
    git, 
    zsh-autosuggestions
    )
    # support bash autocompletion
    # https://dev59.com/KXA75IYBdhLWcg3wg5fs
    #autoload bashcompinit
    #bashcompinit
    source ~/.bash_profile

    if [[ -f /usr/share/bash-completion/completions/lpass ]]; then
            source /usr/share/bash-completion/completions/lpass
    fi

    source $ZSH/oh-my-zsh.sh

    # User configuration

    # export MANPATH="/usr/local/man:$MANPATH"

    # You may need to manually set your language environment
    # export LANG=en_US.UTF-8

    # Preferred editor for local and remote sessions
    # if [[ -n $SSH_CONNECTION ]]; then
    #   export EDITOR='vim'
    # else
    #   export EDITOR='mvim'
    # fi

    # Compilation flags
    # export ARCHFLAGS="-arch x86_64"

    # ssh
    # export SSH_KEY_PATH="~/.ssh/rsa_id"

    # Set personal aliases, overriding those provided by oh-my-zsh libs,
    # plugins, and themes. Aliases can be placed here, though oh-my-zsh
    # users are encouraged to define aliases within the ZSH_CUSTOM folder.
    # For a full list of active aliases, run `alias`.
    #
    # Example aliases
    # alias zshconfig="mate ~/.zshrc"
    # alias ohmyzsh="mate ~/.oh-my-zsh"
    export PATH="/usr/local/opt/thrift@0.9/bin:$PATH"
    zstyle ':completion:*:ssh:*' hosts off
    zstyle ':completion:*:ssh:*' config on

如果有人能帮我解决这个问题，我会非常感激。

谢谢

如果您正在寻找SSH和其他SSH命令（如SCP）的自动补全功能，下面的代码可以实现：

# Highlight the current autocomplete option
zstyle ':completion:*' list-colors "${(s.:.)LS_COLORS}"

# Better SSH/Rsync/SCP Autocomplete
zstyle ':completion:*:(scp|rsync):*' tag-order ' hosts:-ipaddr:ip\ address hosts:-host:host files'
zstyle ':completion:*:(ssh|scp|rsync):*:hosts-host' ignored-patterns '*(.|:)*' loopback ip6-loopback localhost ip6-localhost broadcasthost
zstyle ':completion:*:(ssh|scp|rsync):*:hosts-ipaddr' ignored-patterns '^(<->.<->.<->.<->|(|::)([[:xdigit:].]##:(#c,2))##(|%*))' '127.0.0.<->' '255.255.255.255' '::1' 'fe80::*'

# Allow for autocomplete to be case insensitive
zstyle ':completion:*' matcher-list '' 'm:{[:lower:][:upper:]}={[:upper:][:lower:]}' \
  '+l:|?=** r:|?=**'

# Initialize the autocompletion
autoload -Uz compinit && compinit -i

以下是相关问题的脚本。

h=()
if [[ -r ~/.ssh/config ]]; then
  h=($h ${${${(@M)${(f)"$(cat ~/.ssh/config)"}:#Host *}#Host }:#*[*?]*})
fi
if [[ -r ~/.ssh/known_hosts ]]; then
  h=($h ${${${(f)"$(cat ~/.ssh/known_hosts{,2} || true)"}%%\ *}%%,*}) 2>/dev/null
fi
if [[ $#h -gt 0 ]]; then
  zstyle ':completion:*:ssh:*' hosts $h
  zstyle ':completion:*:slogin:*' hosts $h
fi
