What is Pipe?
A mechanism that connects the output of one command directly to the input of another, enabling command chaining.
Pipes (|) are fundamental to the Unix philosophy of small, composable tools. For example, cat log.txt | grep ERROR | wc -l counts error lines in a log file by chaining three simple commands.
Named pipes (FIFOs) are special files that allow communication between processes. Pipes enable powerful data processing workflows without creating intermediate files.
