A tty provides two output channels, stdout and stderr. Additionally, in some scenarios, one can go outside the standard I/O streams and grab the tty directly. MOD's suggestion may still be useful. It may help if you tell us something about the environment. Linux only? Other *nixes? Versions? PC console? xterm? SSH? Serial line to VT-100? It may help if you tell us about what you're trying to get out of this interaction with the user. I understand if this is for $WORK some details may be hush-hush, but if you can genericize it, it might help give us some context. E.g.: I have to prompt the user for a hostname and an IP address. The hostname entered may or may not be fully-qualified, so I have to figure that out, and qualify it if needed. I also need to do basic syntactic validity checking. Then I need to set $IPADDR and $NAME in the shell. -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
