苹果电脑小技巧。

命令行技巧

  • 移动到行首 ctrl+A
  • 移动当行尾 ctrl+E
  • 往左移一个单词 esc+B
  • 往右移一个单词 esc+F
  • 删除光标前一个单词 ctrl+W
  • 删除光标前所有 ctrl+U

上传rz 下载sz

  • 首先下载 iTerm2 因为自带的 terminal 不行啊
  • 安装 lrzsz brew install lrzsz ， 安装完成后，m1的brew安装位置是在 /opt/homebrew/ ，需要 copy 到 
    1
    2
    3
      # M1 需要
    cd /opt/homebrew/bin
    cp sz /usr/local/bin/ cp rz /usr/local/bin/
  • 下载两个脚本 send-zmodem.sh recv-zmodem.sh

    cd /usr/local/bin 
    sudo wget https://gist.githubusercontent.com/sy-records/1b3010b566af42f57fa6fa38138dd22a/raw/2bfe590665d3b0e6c8223623922474361058920c/iterm2-send-zmodem.sh 
    sudo wget https://gist.githubusercontent.com/sy-records/40f4ba22e3fbdeedf58463b067798962/raw/b32d2f7ac3fa54acca81be3664797cebb724690f/iterm2-recv-zmodem.sh
    sudo chmod 755 /usr/local/bin/iterm2-*

    遍历子目录更新 git

brew

https://brew.sh/ Mac 上面最好用的软件管理工具。
mac上使用brew install /brew cask install安装软件总是先updating HomeBrew…
HomeBrew 关闭自动更新， 减少等待的时间

1
2
3
vim ~/.zshrc

export HOMEBREW_NO_AUTO_UPDATE=true

更稳妥的办法是固定版本

1
2
3
4
brew pin python@3.9 

brew list --pinned
python@3.9

固定好之后，python 就不会被自动更新了。之前遇到过 brew 自动更新了 python 从 3.7 到 3.9 导致了 pycharm 创建的虚拟环境都不能用了。

.zshrc

关于上面的 AWS CLI 如果不想要返回的结果用 less 浏览，可以禁用 pager
The following example sets the default to disable the use of a pager.

2K 显示器 HiDPI

  • intel 可以尝试这个方法 https://blog.csdn.net/qq_37417018/article/details/113701115
  • M1 芯片可以用这个方法 https://sspai.com/post/70141 普通版就可以，不需要 Pro 的高级功能。但 2022-06-19 今天它更新了，不需要 dummy 投影来修改分辨率了。
    而且还支持键盘控制多个屏幕的亮度，修改默认分辨率等高级功能, 真心建议 15 美元买 Pro 版本。 这篇文章也有介绍 https://zzbloc.top/archives/turn-on-hidpi-for-macbook
    关于显示器亮度： 软件上默认最大亮度是你的显示器按键设置的当前值，比如我的显示器按键设置当前值为60%，用 BetterDisplay 控制亮度时，最大值就是60%，我可调整的区间为0-60%，而不能增加到60%以上
