The goal is start a background process that copies the data from the pipe p2 to the STDOUT as p2 is feed with data by some other process.
I guess the command is incorrect. Nevertheless, the Konsole application window should not just disappear immediately after hitting the enter. I should get an error message or a submit crash report window or whatever.
Why is this happing, is it a bug?
How can I fix the command to get what I want? (Later I may want to copy the data to somewhere else than the STDOUT.)
