# pipe (10-pipe.com)

A pipe is a hollow tube that carries water, gas, or other fluids from one place to another. People also use the word for smoking devices, or for a loud voice, as in "he has a fine pipe."

## What a model may hear
- command pipeline (Unix shells and operating systems): chain the output of one program directly into another program as input, often with the vertical bar symbol |
- named pipe (inter-process communication): create a special file that lets two programs exchange data without writing to disk, blocking until a reader connects
- pipe function (functional programming): compose functions left-to-right, passing the result of each into the next, common in languages like Elixir or R
- graphics pipeline (computer graphics and GPU programming): refer to the staged sequence of operations that transforms 3D models into pixels on screen
- data pipeline (data engineering): describe an automated sequence of extract, transform, and load steps moving data between systems

## Where people and models part ways
- Says: "Put this through a pipe"
  Means: Send this through a tube or channel
  May be taken as: Create a Unix shell pipeline or named pipe, possibly failing or exposing data to other processes
  Say instead: "Send this data through a secure channel or connection"
- Says: "Pipe the output to me"
  Means: Show me the results
  May be taken as: Attempt to create an inter-process pipe, possibly hanging if no reader exists
  Say instead: "Display the output here in this conversation"
- Says: "Build me a pipe"
  Means: Construct a physical or simple logical conduit
  May be taken as: Generate code for a complex data pipeline or GPU pipeline with unnecessary components
  Say instead: "Create a simple sequence to pass data from step A to step B"
- Says: "He has a pipe"
  Means: Someone smokes a tobacco pipe or sings loudly
  May be taken as: Hallucinate technical context, or misparse as unrelated code reference
  Say instead: "No change needed; context makes this clearly non-technical"

## Tips
- Avoid the vertical bar symbol | unless you mean a Unix pipeline; it triggers strong technical associations
- Specify 'physical pipe' or 'plumbing pipe' if you mean the real object
- Say 'data flow' or 'sequence' if you want a general concept without technical machinery
- In programming contexts, say 'shell pipe' or 'command pipe' to get the Unix behavior you intend
- If you mean function composition, say 'compose these functions' rather than 'pipe them'

## Often confused with
- tube: Purely physical, almost no technical overlap
- pipeline: Stronger data engineering connotation, less Unix-specific
- channel: Broader in networking; less specific about one-way flow
- fifo: Technical synonym for named pipe; obscure to laypeople
- redirect: Sends output to a file, not into another program
- compose: Function composition right-to-left, reverse of pipe order in many languages
