Unix and Linux tee Utility

The provided text is a technical report on the Unix and Linux tee utility, a command used to duplicate data streams by reading from standard input and writing to both standard output and files. While POSIX standards define a core set of features like appending and ignoring interrupts, the documentation highlights significant behavioral differences between implementations such as GNU, BSD, and BusyBox. Specifically, GNU tee offers advanced error handling for broken pipes, whereas BusyBox focuses on performance through block I/O options. The sources also address security and best practices, explaining why sudo tee is necessary for privileged writes and how to properly redirect error streams. Ultimately, the report serves as a guide for understanding the internal mechanics, I/O performance, and portability challenges of this foundational shell tool.
