mac os 终端命令记录

1、Homebrew更新太慢，更换源

替换brew.git:
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

替换homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

当以上镜像失败后，可重置回原设置

重置brew.git:
cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git

重置homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git

Homebrew Bottles源处理

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

2、xcpretty安装
gem install xcpretty

3、统计近30天在项目里的提交记录

git log --since=30.day.ago --author="$(git config --get user.name 你的邮箱)" --pretty=tformat: --numstat | gawk '{ add += $1 ; subs += $2 ; loc += $1 - $2 } END { printf "added lines: %s removed lines : %s total lines: %s\n",add,subs,loc }' -

4、安装输入法时：https://github.com/rime/squirrel/blob/master/INSTALL.md
安装了以下命令，不需要时可删除

# dev tools:
brew install cmake
brew install git

# libraries:
brew install boost

5、如何快速正确的安装 Ruby, Rails 运行环境
https://ruby-china.org/wiki/install_ruby_guide/

6、gem 镜像安装及源切换
https://gems.ruby-china.org/

7、提示升级ruby

rvm install "ruby-2.5.0"

8、安装完rvm后，再开一个窗口提示rvm找不到
解决办法

可以看到文件.bashrc文件有个路径

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

把此路径放入到文件.bash_profile中即可

然后再执行命令

source ~/.bashrc 

然后新开终端窗口就能正常使用rvm命令了
