output redirection

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.

The blog article on linuxbash.sh explores the use of the `tee` command in Unix-like operating systems, a handy tool for redirecting output to both the terminal and files simultaneously. This feature is particularly useful for logging and debugging, helping users manage command outputs in real-time while saving them for later analysis. The article provides a breakdown of the command's syntax, installation guides for various Linux distributions, practical usage examples, and additional resources for further learning.
