if then fi #

Linux, SHELL

在shell中，零为真，非零为假。

if then fi #

mynum=200

#[和]前后都要有空格
if [ $mynum -eq 200 ]
then
    echo "The condition is true."
fi

编辑之后，按ctrl + O 保存文件
ctrl + T + Z 保持在后台，fg+回车恢复

#!/bin/bash

mynum=200

#[和]前后都要有空格
if [ $mynum -eq 200 ]
then
    echo "The condition is true."
fi

if [ $mynum -eq 300 ]
then
    echo "The variable does not equal 200."
fi

else if #

#!/bin/bash

mynum=300

#[和]前后都要有空格

准备 #

需要一台运行Linux系统的计算机（或虚拟机）

一些基本操作 #

新建或编辑脚本 #

nano myscript.sh

内容 #

ctrl + o 保存，ctrl + x 退出

如何执行脚本 #

权限 #

#给脚本赋予执行的权限
sudo chmod +x myscript.sh

执行 #

执行前查看权限 #

运行 #

./myscript.sh

查看脚本 #

cat myscript.sh

环境 #

使用视频作者给出的示例，https://github.com/CoreyMSchafer/code_snippets/tree/master/Regular-Expressions
使用sublimeText打开的文件，ctrl+f时要确认勾选正则及区分大小写

simple.txt-基础操作 #

直接搜索 #

任意字符 #

这里默认不会显示所有，点击findAll才会出来

有些字符需要加反斜杠转义，比如 . （点）以及 \ （斜杠本身） #

/////，从左到右，和书写方向一致的叫做(正)斜杠。
反之，叫做反斜杠 \

一些元字符 #

.       - Any Character Except New Line 除了换行符的任意字符
\d      - Digit (0-9) 数字
\D      - Not a Digit (0-9) 非数字
\w      - Word Character (a-z, A-Z, 0-9, _) 单词字符，大小写字母+数字+下划线
\W      - Not a Word Character 非单词字符
\s      - Whitespace (space, tab, newline) 空白字符，空格+tab+换行符
\S      - Not Whitespace (space, tab, newline) 非空白字符

\b      - Word Boundary 边界字符-单词边界
\B      - Not a Word Boundary 非单词边界(没有单词边界)
^       - Beginning of a String
$       - End of a String

[]      - Matches Characters in brackets
[^ ]    - Matches Characters NOT in brackets
|       - Either Or
( )     - Group

Quantifiers:
*       - 0 or More
+       - 1 or More
?       - 0 or One
{3}     - Exact Number
{3,4}   - Range of Numbers (Minimum, Maximum)


#### Sample Regexs ####

[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+

模板分为list template和single template

文件夹结构 #

content目录结构

list template （列表模板） #

single template （单页模板） #

特点 #

所有的列表之间都是长一样的（页眉，页脚，及内容（都是列表））
所有的单页之间都是长一样的（一样的页眉页脚，一样的内容布局）

部分代码解释 #

单页探索 #

list page templates #

介绍 #

hugo是用来构建静态网站的
但是也可以稍微做点动态生成的事
这里使用的版本是v0.26（很久之前的版本）

备注：标题短代码之前（不包括短代码这篇）的笔记是回溯的，所以没有复制源代码下来，直接在视频再次截图的

在Windows上安装hugo #

到github release下载，然后放到某个文件夹中
设置环境变量
验证环境变量
最后验证hugo版本

hugo version

创建一个新的网站 #

使用代码生成

hugo new site

文件夹结构

使用主题 #

这里是https://themes.gohugo.io
这里使用的是ga-hugo-theme（github中查找），并放到themes文件夹中

之后在config.toml中使用主题

baseURL = "http://example.org/"
languageCode = "en-us"
title = "My New Hugo Site"
theme = "ga-hugo-theme" #添加这句话

启动博客
hugo serve
地址
localhost:1313

创建md文件 #

使用hugo new a.md把文件创建在content/a.md或者hugo new dir2/d.md把文件创建在content/dir2.md下，这讲创建后的结构目录为
- 总共5个文件，可以使用localhost:1313访问博客（默认列举所有（包括子文件夹）文件
- 可以使用 localhost:1313/dir3访问dir3下所有文件列表(list)，localhost:1313/dir1访问dir1下所有文件列表（都是content的直接子文件夹）
- 如果没有dir1/dir2/_index.md这个文件，则不能直接使用localhost:1313/dir1/dir2访问dir1/dir2下所有文件
- 查看dir1/dir2/index.md文件及效果

frontmatter (前言) #

可以使用YAML，TOML，或者JSON
md编码及效果
