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?

    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 
    ls -l | wc -l

    There are several types of pipelines, check here shell usage guide for beginners #pipelines

    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?

    Vivien.
