7z 如何传递密码,避免提示?

dru*_*rum 10 7-zip

在 Linux 中,我使用 7z 来解密 *.7z 加密文件。有没有办法通过管道或任何其他可以自动化的方法传递密码?

我试过了,echo password | 7z x archive.7z但仍然提示我输入密码。

7z 如何传递密码,避免提示?

有没有办法通过管道或任何其他可以自动化的方法传递密码?

尝试使用与以下示例类似的语法运行提取命令,看看它是否适合您的需要,在传入之前相应地设置密码变量,或者您通常会使用您在脚本中使用的逻辑来执行此操作,等等。

确保它的密码或变量值直接在-pswitch 之后,之后没有空格-p

带密码变量的隐式路径提取

password="<password>"; 7z.exe x -p$password "archive.7z"

  • 还是很危险的。ps 扫描将把我所有的密码带给其他人 (2认同)

-p 选项比您预期的更安全。当 7zip 首次运行时,如果它检测到 -p 选项,它将将该值复制到其他位置,并覆盖进程树中可见的值。因此,如果您执行“ps -aux”,您可能会在 -p 之后看到“/usr/bin/7za -p******** x arch.7z”而不是实际密码。至少这是它在 Linux 上的工作方式,您可以配置内核,使进程树对普通用户不可见。

  • 清除密码是个好主意,但当密码可见时,它仍然会留下一个小窗口。 (3认同)
