在bash调试运行期间隐藏信息 [英] Hide information during bash debug run

问题描述

我们在shell脚本中调试了run(bash -x ./my_script.sh)，以了解/显示它的作用.但是这样做可能会显示一些我不希望看到的敏感信息，例如密码.我的脚本从安全库中提取密码，并在需要时将其作为变量传递给脚本.

We do debug run(bash -x ./my_script.sh) in a shell script to understand/show what it is doing. But in doing so it might show some sensitive information that I dont want to be visible, such as passwords. My script extracts the password from a secure vault and passes it as a variable within the script when required.

所以，我想了解一下是否有一种方法可以在Shell脚本的调试运行期间哈希/隐藏此类敏感信息?(大概没办法吗?)

So, I want to understand if there is a way to hash/hide such sensitive information during a debug run of shell script? (Probably No way?)

推荐答案

对具有敏感信息的部件禁用调试，然后重新启用它.

Disable debugging for the part with sensitive information and re-enable it afterwards.

if [[ $- =~ x ]]; then debug=1; set +x; fi

# your code with sensitive information

[[ $debug == 1 ]] && set -x
