xterm buffers program output?
Whenever I run a program through an xterm it seems to buffer all of the output (to stdout) until the program is finished. I thought this was just a PHP thing but I wrote similar scripts in C and Perl and they do the same.
Scripts:
PHP
PHP Code:
for($i=0;$i<10;$i++)
{
echo "Hi...\n";
flush();
sleep(2);
}
Perl
Code:
for($i=0;$i<10;$i++)
{
print "Hi...\n";
sleep(2);
}
C
Code:
#include <stdio.h>
void main()
{
int i;
for(i=0;i<10;i++)
{
printf("Hi...\n");
sleep(2);
}
}
They all do the same thing... I get
Hi...Hi...Hi...Hi...Hi...Hi...Hi...Hi...Hi...Hi...
after 20 seconds.
Maybe I'm just stupid but I could swear I never had this problem when writing QBasic and C programs for DOS years ago...
I have also tried things like this:
./program.php | more
./program.php > output
But the output is still buffered until the end...
