I've noticed a bug in the "autowidth" feature more, and is probably in others. The call to the function get_terminal_width_height() passes in a file descriptor but that file descriptor is never used, instead the ioctl() is called with 0. In more_main() the call to get_terminal_width_height() passes 0 as the file descriptor instead of fileno(cin). This isn't a problem when you more a file (e.g. "more /etc/passwd") but when you pipe a file to it (e.g. "cat /etc/passwd | more") the size of the terminal cannot be determined because file descriptor 0 is not a terminal. The fix is simple, I've attached a patch for more.c and get_terminal_width_height.c. BAPper
