Re^4: Slicing the output of a command

[marioroy]

+1 BrowserUk. I'm not sure if the behavior is the same in Windows, but the 'cat command' receives a PIPE signal and exits once count lines have been read by the 'head command'.

Windows has no signals, so no SIGPIPE there.

You're correct, however, marioroy's point holds. When head has read its 4 lines it closes the pipe and effectively prevents cat (or type or copy etc.) from reading further.

(That doesn't stop it from be a Useless use of cat though.)
