Hello everyone,
here, I would like to know what "pipeline" means in English, and in computing, of course... Here is an excerpt from the sentence containing this word: "Data sent down a stream from your PHP script to the destination file or network server flows down the write pipeline."
Can you explain it to me?
Vivien.

Hello,
The pipeline is like a tube (not YouTube ;-))
On one side the data enters and on the other side the data exits
In short, if you have a command that sends a result, then we use a pipeline to transmit that result which will be picked up on the other side of the tube (pipeline) to be processed
For example, if you do
ls -l then the files will be displayed
The command wc -l allows you to display the number of lines in a file
So, the output of ls -l will be passed through a pipeline and at the output of the pipeline, the result will be taken by wc -l and the result will no longer be the display of the files but the number of files (lines)
By default, the output is directed to the STDOUT file descriptor
There are several types of pipelines, check here shell usage guide for beginners #pipelines

ls -l | wc -l

Hello everyone!
So, does anyone know what "pipeline" means in computing? I've searched everywhere, and apart from the definition from CCM,
here (the 4th part from the bottom), I haven't found anything...
Would anyone have a definition that fits better with my text?
