Piping in UNIX is a mechanism for inter-process communication, using the concepts of stdin (standard input) and stdout (standard output). In Unix and Unix-like operating systems, a pipe is a method of redirecting the output of one process to the input of another.

Here is a step-by-step explanation:

1. In Unix-like operating systems, when a process is created, it opens three data streams: stdin, stdout, and stderr. These streams are typically connected to the terminal window where the process was initiated, but can also be redirected.

2. The pipe operator (|) tells the system to use the output of the command on the left as the input to the command on the right.

3. For example, if you want to display the contents of a file, but only want to see the lines that contain a certain string, you could use the "cat" command to display the file, then pipe that output to the "grep" command to filter it.

4. The command would look something like this: cat myfile.txt | grep "mystring"

5. The output of the "cat" command (the contents of the file) becomes the input to the "grep" command, which filters it and displays only the lines that contain "mystring".

The practical significance of piping is that it allows you to chain together commands to perform complex tasks with a single command line. It also allows data to be processed as it is generated, rather than having to be stored and retrieved, which can be more efficient for large amounts of data.
