# 在 Bash 和 Zsh 运行无痕／私密命令

> 只要在命令前面加一个空格，它就不会被存进 ~/.bash\_history。例如  qrencode -o out.png "Some secret text"

# Bash

只要在命令前面加一个空格，它就不会被存进 `~/.bash\_history`。例如 ` qrencode -o out.png "Some secret text"`

# Zsh

启用下面这个选项之后，就能在命令前加一个空格来运行私密命令，避免它被存进 `~/.zsh\_history`。

```
setopt HIST_IGNORE_SPACE
```
