See: https://github.com/Hansimov/blog/blob/main/docs/notes/configs/.bash_aliases

# aliases
alias gs="git status"
alias gb="git rev-parse --abbrev-ref HEAD"
alias gba="git -P branch"
alias gd="git diff"
alias gdp="git -P diff"
alias gdh="git diff HEAD^ HEAD"
alias gl="git log"

alias gcan="git commit --amend --no-edit"
alias gp="git push"
alias gpf="git push -f"
alias gacp="git add -u && git commit --amend --no-edit && git push -f"

alias ta="tmux a"
alias td="tmux detach"
alias tn="tmux new -s"
alias tl="tmux ls"
alias ts="tmux select-pane -T"

alias k9="kill -9"
alias lt="ls -lt"

绑定按键

用下面的命令显示按键对应的字符：

showkey -a

ctrl + D 退出该界面。

将下列内容添加到 ~/.zshrc 中：

# bind keys
bindkey "^[[1;5C" forward-word
bindkey "^[[1;3C" forward-word
bindkey "^[[1;5D" backward-word
bindkey "^[[1;3D" backward-word
bindkey "^[[1~"   beginning-of-line
bindkey "^[[4~"   end-of-line
bindkey "^[[3~"   delete-char
bindkey "^[^[[3~" delete-word

重启 zsh 或者 source ~/.zshrc 使配置生效。

自动建议

cd ~
mkdir .zsh && cd .zsh
touch zsh-autosuggestions.zsh

复制下列脚本内容到 ~/.zsh/zsh-autosuggestions.zsh 中：

• https://raw.githubusercontent.com/zsh-users/zsh-autosuggestions/master/zsh-autosuggestions.zsh

将下列内容添加到 ~/.zshrc 中：

# auto suggestions
ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE="fg=#ff00ff"
source ~/.zsh/zsh-autosuggestions.zsh

See: zsh-autosuggestions

• https://github.com/zsh-users/zsh-autosuggestions/blob/master/INSTALL.md#manual-git-clone

自动补全

cd .zsh
git clone --depth 1 -- https://github.com/marlonrichert/zsh-autocomplete.git

将下列内容添加到 ~/.zshrc 中：

# auto complete
source ~/.zsh/zsh-autocomplete/zsh-autocomplete.plugin.zsh
# style of auto complete
zstyle ':completion:*'  list-colors '=*=96'

并注释掉所有 compinit 相关的语句：

# # Use modern completion system
# autoload -Uz compinit
# compinit

然后创建 ~/.zshenv 文件：

cd ~
touch .zshenv

将下列内容添加到 ~/.zshenv 中：

skip_global_compinit=1
