But, Java can read from files/sockets and other generic InputStreams unbuffered. So I was wondering if there is a command that will make stdin go to a file so that Java can open that file and read it unbuffered? I know I can do something like cat ->file but that makes it hard to sync stdout and stderr (both are unbuffered in Java) with the file version of stdin -- Aryeh M.

I am pretty convinced by the following test it is not working as advertised= :

aryehl@neomarx:~/Desktop % cat foo.c
#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>

int main()
{
=C2=A0 =C2=A0 int in=3Dfcntl(STDIN_FILENO, F_DUPFD, 0);
=C2=A0 =C2=A0 int out=3Dfcntl(STDOUT_FILENO, F_DUPFD, 0);
=C2=A0 =C2=A0 char c=3D0;

=C2=A0 =C2=A0 do {
=C2=A0 =C2=A0 =C2=A0 =C2=A0 read(in,&c,1);
=C2=A0 =C2=A0 =C2=A0 =C2=A0 write(out,&c,1);
=C2=A0 =C2=A0 } while(c!=3DEOF);
}
aryehl@neomarx:~/Desktop % !cc
cc foo.c
aryehl@neomarx:~/Desktop % stdbuf -i 0 -o 0 ./a.out
this is not echoing!
this is not echoing!
neither is this
neither is this
^C
aryehl@neomarx:~/Desktop %

stdbuf only works for stdio buffering of which read(= 2) and write(2) aren't.

I also tried it with System.in.read() in Java and it was also buffered
but according to the openjdk source it appears that this is on
purpose.

When you just `./a.out` you&= #39;re being bitten by the tty.
You can manipulate that termi= nal to do what you want.=C2=A0 Start reading termios(4).

Without a tty you will only get a character at a time with the follo= wing:

#include <unistd.h>

int main(int argc,= char **argv)
{
=C2=A0 char ch;
=C2=A0 for(;;){
=C2=A0 =C2=A0 s= size_t r =3D read(0,&ch,1);
=C2=A0 =C2=A0 if(!r) break;
=C2=A0 = =C2=A0 write(1, &ch, 1);
=C2=A0 }
=C2=A0 _exit(0);
}
