An ordinary redirection opens a file descriptor with regular file semantics. Some shells implement "process" redirection which is similar to a pipe. The main difference between pipe file descriptors and "file" file descriptors is that pipes implement a sort of flow control. Draining a pipe causes the reader to block rather than receive an EOF. Filling up the pipe will cause the writer to block. Other differences are the way the file descriptors respond to various other syscalls. For instance, you can't do a 'seek' on a pipe. _______________________________________________ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
