The character 004 is not EOF. When typing at a terminal which is set to "cooked" mode, you use the keystroke control-D to tell the terminal driver that it should send EOF to the program reading from the terminal. Control-D is also used in other contexts (such as typing at a terminal in "raw" mode) to produce the character 004. In the case of a pipe, a reader will not see EOF until all writers have closed the pipe (typically when they exit). paul _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
