Environment construction procedure

Finder

Show the following in a new Finder window: Change the display item of to Drive.

About installing Notion. For multi-user, under the user directory Place in the Application directory

Permission setting

Since it is basically used by multiple users, give it permission.

(I often forget this and have trouble)

$ sudo chown -R $(whoami):admin /usr/local/*
$ sudo chmod -R g+w /usr/local/*

Initial settings that you definitely want to do when you buy a Mac-Qiita

use zsh

The default from now on is zsh. If it's still bash, leave it in zsh.

chsh -s /bin/zsh
echo $SHELL
cat /etc/shells

zsh-autosuggestions/INSTALL.md at master · zsh-users/zsh-autosuggestions

git clone https://github.com/zsh-users/zsh-autosuggestions ~/.zsh/zsh-autosuggestions

# .Added to zshrc
source ~/.zsh/zsh-autosuggestions/zsh-autosuggestions.zsh

Terminal environment

Use fish for completion and starship for the theme However, it is not set as the default shell.

# terminal
brew install fish
brew install startship
echo 'starship init fish | source' >> ~/.config/fish/config.fish
echo 'alias c="clear"' >> ~/.config/fish/config.fish

About shell

Making fish the default shell can be a hassle. Set the default to zsh and try calling fish each time.

zsh

Summary of reading order and usage tips of zsh configuration file --Qiita

zshenv> zprofile> zshrc> zlogin .zshenv As you can see from the order, it is always loaded first in any case. .zprofile It is loaded only once in the case of a login shell. .zshrc Only loaded for login and interactive shells.

For the time being. Should I write it in zshrc?
