I have a C program that continously outputs info to stdout. The problem is that I am redirecting the stdout and stderr to a file and stdout is written at the end of the problem rather than continously to the file. This could be a problem if for example the program is killed and the stdout output is lost. On the other hand, stderr is written continuously to the file.
Thats the way I am doing the redirection of the stdout and stderr.
Any ideas how can I redirect the stdout to the file continuously rather than at the end of the program?

Hi everybody,
I am trying to do the thing you see in the title, and I can't simply do
a=$(svn up)
echo $a
because the program (svn) gives output on lots of lines and in the variable the output is stored on only one line (resulting in a horribly formatted text). Any tips?
Thanks,... (2 Replies)
Hello,
I have a script (videostream.sh) which invokes the GStreamer command-line tool gst-launch with all the correct command line parameters. When I invoke this program, I add the '&' character at the end to make it a background task, so that my script can complete and exit, i.e.
