# 在 Bash 和 Zsh 執行無痕／私密指令

> 只要在指令前面加一個空格，它就不會被存進 ~/.bash\_history。例如  qrencode -o out.png "Some secret text"

# Bash

只要在指令前面加一個空格，它就不會被存進 `~/.bash\_history`。例如 ` qrencode -o out.png "Some secret text"`

# Zsh

啟用下面這個選項之後，就能在指令前加一個空格來執行私密指令，避免它被存進 `~/.zsh\_history`。

```
setopt HIST_IGNORE_SPACE
```
