file redirection

In the world of Unix and Linux, mastering the command line is an essential skill for any user, developer, or system administrator. One of the fundamental aspects of working in the terminal is the ability to control where output goes. This can mean sending the output of a command to a file instead of your screen, or appending logs at the end of an existing file. This is where the redirection operators > and >> come into play. Understanding how to use these tools effectively can greatly enhance your productivity and capabilities in shell scripting or day-to-day tasks.

In the realm of Unix-like operating systems, certain command-line utilities boast an elegance and versatility that underscore the philosophy of doing one thing well. One such utility is the tee command, a lesser-celebrated but incredibly powerful tool when it comes to managing command output in Unix and Linux systems. Today, we'll explore how you can use tee to split command output, thereby enhancing your productivity and data management efficiency in terminal sessions. The tee command reads from standard input and writes to standard output and files. This utility is named after the T-splitter used in plumbing, which splits water flow in two directions, mirroring how the command sends output to both a file and the screen.
