Working on pipe ‘|’ and wait() for Linux shells 🍽️

Today I am trying to finish up my Linux shell. I am looking through the functions I wrote to determine where I need to use the wait() or waitpid() command. As I understand it, if a function is using a pipe ‘|’ then the parent process which is reading from the pipe should be told to wait for its child process which is feeding into the pipe. That makes sense. If you’re a waiter, you need to wait for the food to be put on a plate before you go and try to bring it to a patron. 🍽️

Refreshing myself on how to do MySQL statements. We’re learning some server side code and creating databases for web scripting class. This is helpful since I want to create a web based business soon.

Trying to stay focused on writing my linux shell, while being much more interested in writing for my growing newsletter about changing careers into tech/web/programming. Email me here if that’s interesting to you wrmoriarty+list@gmail.com
