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：
# Incremental completion for zsh
# by y.fujii <y-fujii at mimosa-pudica.net>, public domain autoload -U compinit
zle -N self-insert self-insert-incr
zle -N vi-cmd-mode-incr

compdef -d scp
compdef -d tar
compdef -d make
compdef -d java
compdef -d svn
compdef -d cvs # TODO:
# cp dir/ now_predict=0 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
