shell编程语言

一.什么是编程语言

1.编译型语言

程序在执行之前需要一个专门的编译过程，把程序编译成为机器语言文件，运行时不需要重新翻译，直接使用编译的结果就行了。

程序执行效率高，依赖编译器，跨平台性差些。如golang、C、C++。

2.解释型语言

程序不需要编译，程序在运行时由解释器翻译成机器语言，每执行一次都要翻译一次。

因此效率比较低，这个效率是针对cpu而言的，你们普通的人类就别琢磨语言的性能了；

比如Python/JavaScript/ Perl /ruby/Shell等都是解释型语言。

二.vim插件模板

vim ~/.vimrc

syntax on
set nocompatible
"set number
"filetype on
"set history=1000
"set background=dark
""set autoindent
"set smartindent
"set tabstop=4
"set shiftwidth=4
"set showmatch
"set guioptions-=T
"set ruler
"set nohls
"set incsearch
""set fileencodings=utf-8

if &term=="xterm"
    set t_Co=8
    set t_Sb=^[[4%dm
    set t_Sf=^[[3%dm
endif
