I have 2 users, user A and user B. The user B creates a named pipe with all permissions(rwxrwxrwx).
./test < input.txt (test is a program that writes from stdinput to the pipe).
USER A : reads from the named pipe
The problem is that the USER B cannot open the pipe as it claims that has no permission to open when clearly that's not the case.
But if i dont redirect the input the USER B has no problem opening it.
What is the problem of redirecting the input?
