I want to implement pipes in linux through my own program. Here is my code :


The pipe works fine but. But when I run the program as ./pipe ls | wc , the elements of argv are not printed for which code is written in the beginning. Why aren't those lines giving any output?

Perhaps it would be better to tell us exactly what you are getting, and what you are expecting.

thanks for your interest, but i got the answer. In the argument I was not supposed to use the '|' symbol. So shell redirects the output when it sees | symbol. the correct way to run it is by skipping the | symbol as : ./pipe ls wc
 
Don't get me started about those stupid light bulbs.
