eval

The blog details using `eval` and `printf -v` in Bash scripts to create dynamic filenames for output redirection. Filenames are generated from runtime data for uniqueness and relevance, leveraging `printf -v` for string formatting and `eval` for executing commands securely. Practical examples include timestamping files, essential in automation but warrant caution with `eval` to prevent security risks.

This blog post provides detailed guidance on auditing Linux Bash scripts to detect and mitigate risks associated with the `eval` and `exec` commands. It offers practical advice on manual script reviews, input validation, and sanitization to prevent security breaches from malicious code execution. Examples illustrate both risky and safer usage, promoting best practices such as command whitelisting.
