brew combines iTerm2 fancy fun with terminal commands for MacOS software management

1. Background requirements

  When I just got a new Mac computer for work, many common commands on Linux were not installed. For example, wget，git，telnet……these commands are often used in work. Friends who are familiar with Linux know that there is a powerful yumcommand, so I can use it directly, hehe I found an error, and after stepping on the pit, I found that the command in the original Mac is called brew, and it can also have the following operations;

brew install git
brew install telnet
brew install wget
……
复制代码

  But once you find brewthat you need to install it, a lot of people on the Internet tell you that you can use the following instructions to install it directly;

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
复制代码

  I tried it myself and found that an error was reported curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused, as shown in Figure 1.1;

  The reason is raw.githubusercontent.comthe old beauty. Without jailbreak, it is basically impossible to connect, and it happens to be very slow to connect. How to install it? Reference chapters 2. 安装brew;

2. Install brew

2.1 Download and installation of domestic base stations

  brewThe full name Homebrewis a package management tool under the MacOS platform, which has many practical functions such as installation, uninstallation, update, viewing, and search. With a simple command, you can implement package management without you needing to care about various dependencies and file paths, which is very convenient and fast. A must-have artifact for the terminal, I said the same when Jesus came! The first chapter mentioned that the direct official website cannot be downloaded. Is there any network Lei Feng in China to help solve it? There really is, someone moved it back to the domestic base station and used the following instructions to solve the installation;

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
复制代码

  During the installation process, you will be asked to select the base station from which to download the mirror image. Generally, you can choose 1it, and for some options Y/N, just follow the prompts to fill Yin it, and the installation is complete until Figure 2.1 appears;

Figure 2.1 Prompt for domestic mirror installation

2.2 Activate environment variables

  Activate the environment variable according to the red line in Figure 2.1, that is, run the following statement;    pay attention rowyetto the blogger's account, everyone's is different, do not copy; pay attention rowyetto the blogger's account, everyone's is different, do not copy; Note rowyetFor the blogger's account, everyone's is different, don't copy it; it's three times, try your best;

source /Users/rowyet/.zprofile
复制代码

2.3 Test brew

  Use the following command to do a test. If no error is reported, in principle, brew is installed.

# 更新brew
brew upgrade   

# 安装cask
brew install cask

# 安装 wget
brew install wget

# 安装 git
brew install git

# 安装telnet
brew install telnet
复制代码

3. Install iTerm2

  MacOSThe built-in terminal attaches great importance to the lack of charm, and the appearance cannot be edited. After tossing and turning around in MacOS, FinalShell，JetBrainsafter getting used to it, I finally decided to choose iTerm2it. It iTerm2is the MacOSbest terminal, I said!

• Official website: iterm2.com/
• Official website download: You can also download it directly from the official website. The download is a tarball, which can be used after decompression, but we brewwill not download it from the official website if we have it, and use the brew command to download it.

  After the installation is complete, find the chart in Figure 3.2 on the launchpad;

4. Install oh-my-zsh

  Why oh-my-zsh? It's simple: smarter shellautocompletion, command option hints, richer themes. So that your terminal is not singled out, you can pretend to be a god at first sight. After configuration, as shown in Figure 4.1.

Figure 4.1 oh-my-zsh configuration effect

  The installation and configuration steps are as follows;

# 先查看自己iterm2使用的是否是zsh，利用echo $SHELL ，返回/bin/zsh则是
echo $SHELL

/bin/zsh # 返回值

# 如果不是，则执行以下指令
chsh -s /bin/zsh

# 再执行echo $SHELL验证

# 没问题后用cat /etc/shells  确认下/bin/zsh为该系统内的有效sh
cat /etc/shells                                                         1 ↵

# Ftpd will not allow users to connect who are not using
# one of these shells.

# 返回值
/bin/bash
/bin/csh
/bin/dash
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh

# 下载安装git和wget，已安装的略过
brew install wget
brew install git

# 找一个空文件夹
cd /Applications/tools/
mkdir zsh
cd zsh

# 利用wget下载oh my zsh安装包：
wget https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh

#  或者利用git下载oh my zsh安装包，二选一，不要重复操作
git clone https://gitee.com/mirrors/oh-my-zsh.git

# ls观察下自己下载的文件是一个install.sh
chmod 755 install.sh

7. Use of the fuck command

2. Then you enter fuck;
3. She returns you a relatively correct grammar, then you press the enterkey to execute the command, and press ctrl+cto terminate the command, smart, fun, right?

Note: Fucking is fun, but it is not necessarily accurate. Don't mess with it. You still have to look at the instruction code yourself. Although the wine is good, don't be greedy!
