Not neccessarily - the only difference is the y and newline following it that do not appear in the log file. That means these two characters were not output via the same mechanism as the rest of the text. Now, it's possible for a program to set its terminal into raw mode to receive every input character, even every key press, immediately and without translation. The terminal doesn't even neccessarily echo them, but may let the application do that itself. These characters might not even be output via stdout/stderr, but could be sent to the terminal directly. On the other hand, a Unix terminal has a whole lot of options to handle input and output internally, without an application's interaction, and maybe without reflection on any of the standard I/O channels. You might consult man stty or just study the output of stty --help on this. It's sufficient to pass it a response by pipe to make it suppress the progress display as well as the newline after the input prompt. In theory current ptytee and tterminal should use a PTY on input and output so there is something wrong again. Does ptytee pass the y-newline sequence as keyboard actions? If not, this might be sufficient to trigger the alternate behaviour of pacman already - the missing progress display indicates that this has happened indeed. So there's probabely nothing wrong with ptytee and tterminal, the unwanted behaviour is just due to pacman's overly cautious method of input acquisition, which cannot be correctly reflected by any means except real keyboard entry. And even that might not be able to capture the automatic action of the terminal itself on input, because they might not appear at all in the output stream. -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) --- Mit freundlichen Grüßen, S.

Hallo Martin,

It is possible that pacman works different if output is not connected to
a pseudotermial. If so I fear you must debug yourself.
That's it - pacman senses whether it's talking to a real
(controlling) terminal or to a pipe, and adjusts its output accordingly.
To a real terminal, e.g. it sends progress indicators, while it doesn't do
that if it's connected to a pipe. (Any Unix program can do that, it just
takes a couple of ioctl calls, AFAIR.)
But pacman's sense logic even has a flaw: it doesn't discern whether it's
its _output_ or its _input_ which is connected to a pipe. So even if you
only feed it input (which might be useful in a script if it's overly
interrogative during some operations), it will _not_ output any progress
information, which uses terminal control data (aka escape sequences).
To the Unix specialists: Is there a possibility to get a copy of the data
the terminal receives?
Well, I'm not a Unix specialist, whatever that might mean. It's just that
I found out a couple of facts about these things by tinkering about...
If it's a real terminal, like the /dev/tty pseudo consoles, yes, there
is. Their output is reflected on the /dev/vcs(a) devices, which are
character devices containing either the text only or text-attribute pairs
of the console display.
The following (FPC) program can read them and display the content (text
only):
PROGRAM catvcc;
USES SysUtils, Crt;
VAR
i: integer;
C: char;
Z: string;
v: text;
d: FILE OF byte ABSOLUTE v;
CONST
l: byte {integer} = 80;
BEGIN
IF ParamCount 1 THEN Halt (1);
CheckBreak:= true;
Assign (d, '/dev/vcsa'+ ParamStr (1)); Reset (d);
Read (d, l); Read (d, l); // get line length
Assign (v, '/dev/vcs'+ ParamStr (1)); Reset (v); Z:= ''; i:= 0;
