shell终极操作

1、安装zsh

Mac : 直接看下一节

Redhat/centos ：sudo yum install zsh

Ubuntu ：sudo apt-get install zsh

2、安装oh my zsh

自动安装

   wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh

手动安装

1.使用git clone 项目

git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh

2.备份~/.zshrc文件

cp ~/.zshrc ~/.zshrc.orig

3.创建新的zsh配置文件

cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

4.设置zsh为默认shell

chsh -s /bin/zsh

接下来配置适合自己Zsh

1.主题修改，我比较喜欢前面是$符号，所以选择了steeef这款主题

$ vim ~/.zshrc

配置文件里找到：

ZSH_THEME="robbyrussell"

修改为：

ZSH_THEME="steeef"

3、下载incr

下载地址： http://mimosa-pudica.net/zsh-incremental.html

为了防止该网址将来不能访问，因此我把代码摘录如下：

autoload -U compinit
zle -N self-insert self-insert-incr
zle -N vi-cmd-mode-incr

compinit

function limit-completion
{
    if ((compstate[nmatches] <= 1)); then
        zle -M ""
    elif ((compstate[list_lines] > 6)); then
        compstate[list]=""
        zle -M "too many matches."
    fi
}

function correct-prediction
{
    if ((now_predict == 1)); then
        if [[ "$BUFFER" != "$buffer_prd" ]] || ((CURSOR != cursor_org)); then
            now_predict=0
        fi
    fi
}

function remove-prediction
{
    if ((now_predict == 1)); then
        BUFFER="$buffer_org"
        now_predict=0
    fi
}

function show-prediction
{
    # assert(now_predict == 0)
    if
        ((PENDING == 0)) &&
        ((CURSOR > 1)) &&
        [[ "$PREBUFFER" == "" ]] &&
        [[ "$BUFFER[CURSOR]" != " " ]]
    then
        cursor_org="$CURSOR"
        buffer_org="$BUFFER"
        comppostfuncs=(limit-completion)
        zle complete-word
        cursor_prd="$CURSOR"
        buffer_prd="$BUFFER"
        if [[ "$buffer_org[1,cursor_org]" == "$buffer_prd[1,cursor_org]" ]]; then
            CURSOR="$cursor_org"
            if [[ "$buffer_org" != "$buffer_prd" ]] || ((cursor_org != cursor_prd)); then
                now_predict=1
            fi
        else
            BUFFER="$buffer_org"
            CURSOR="$cursor_org"
        fi
        echo -n "\e[32m"
    else
        zle -M ""
    fi
}

function preexec
{
    echo -n "\e[39m"
}

function vi-cmd-mode-incr
{
    correct-prediction
    remove-prediction
    zle vi-cmd-mode
}

function self-insert-incr
{
    correct-prediction
    remove-prediction
    if zle .self-insert; then
        show-prediction
    fi
}

function vi-backward-delete-char-incr
{
    correct-prediction
    remove-prediction
    if zle vi-backward-delete-char; then
        show-prediction
    fi
}

function backward-delete-char-incr
{
    correct-prediction
    remove-prediction
    if zle backward-delete-char; then
        show-prediction
    fi
}

function expand-or-complete-prefix-incr
{
    correct-prediction
    if ((now_predict == 1)); then
        CURSOR="$cursor_prd"
        now_predict=0
        comppostfuncs=(limit-completion)
        zle list-choices
    else
        remove-prediction
        zle expand-or-complete-prefix
    fi
}

4、执行如下命令：

cd ~/.oh-my-zsh/plugins/
mkdir -p incr
cd incr
touch incr-0.2.zsh
（将上面链接中的代码复制粘贴到incr-0.2.zsh文件中）
chmod 777 incr-0.2.zsh

5、配置 .zshrc 文件:

vim ~/.zshrc

末尾加入

source ~/.oh-my-zsh/plugins/incr/incr*.zsh

6、 source ~/.zshrc     #使其立即生效
