  1. Pipeline overview and related API applications 1.1 key concepts related to pipelines As one of the first Unix IPC formats supported by Linux, pipelines have the following features: The pipeline is half-duplex, and data can only flow in one

I have been using Linux (UBUNTU) for a long time, but I have been insisting on using it. I am determined to learn Linux technology. Although sometimes it is easier to use Windows in some aspects of development, I still insist on using Linux to solve

In Linux, operations on pipelines are mainly concentrated on blocking and non-blocking situations. The main difference between these two cases is that in writing, the main difference is:   In the case of blocking or non-blocking, the read operation

In Linux, If you download and install an application, it is very likely that the prompt "command not found" appears when you type its name. If you find the executable file in the installation target folder every time, it is too cumbersome to find

Generally, the operating system can use three methods to represent the current time and date of the system: ① the simplest method is to directly use a 64-bit counter to count the tick of the clock. ② The second method is to use a 32-bit counter to
