libpipeline is a C library for setting up and running pipelines of processes, without needing to involve shell command-line parsing which is often error-prone and insecure. This relieves programmers of the need to laboriously construct pipelines using lower-level primitives such as fork and execve.

pipe() creates a pipe, a unidirectional data channel that can be used for interprocess communication. The array pipefd is used to return two file descriptors referring to the ends of the pipe. pipefd[0] refers to the read end of the pipe. pipefd[1] refers to the write end of the pipe. Data written to the write end of the pipe is buffered by the ...

Pipes and FIFOs (also known as named pipes) provide a unidirectional interprocess communication channel. A pipe has a read end and a write end. Data written to the write end of a pipe can be read from the read end of the pipe.

2019年8月13日 · Why is the pipe not working? See: "I set variables in a loop that's in a pipeline. Why do they disappear after the loop terminates? Or, why can't I pipe data to read?" Because the pipe introduced a new subshell. Also, don't loop when you don't need to:

2005年5月6日 · Using ps is a bit different to ps -U Henry -o pid,bsdstart,state,rss,args -H, but nevertheless it should work. I just ran first the full command (with my username) and piped it to grep and it gave the correct output, then I aliased it to ps, and ran that, and it worked, so I don't know what's going on. Also, alias | grep ps worked as well. D:
