执行命令而不将其保留在历史记录中 [英] Execute a command without keeping it in history

问题描述

我想执行一些命令，但是我不想将它们存储在命令历史记录中.这样，没人能在 .bash_history 文件中进行搜索.

I want to execute some commands, but I don't want to store them in the command history. So that nobody will be able to search them in the .bash_history file.

有没有一种方法可以这样执行Bash命令?

Is there a way how to execute Bash commands this way?

推荐答案

以空格开头的命令将不会包含在历史记录中.

Start your command with a space and it won't be included in the history.

请注意，这确实需要设置环境变量 $ HISTCONTROL .

Be aware that this does require the environment variable $HISTCONTROL to be set.

• 检查以下命令是否返回 ignorespace 或 ignoreboth :

 echo $HISTCONTROL

要添加环境变量(如果缺少)，可以将以下行添加到Bash配置文件中.例如，保存到％HOME/.bashrc .

 export HISTCONTROL=ignorespace

再次获取配置文件后，空格前缀的命令将不会被写入 $ HISTFILE .

After sourcing the profile again, space-prefixed commands will not be written to $HISTFILE.
