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.
Code:
gst-launch .... &
When I look at the process list, gst-launch appears correctly.
However, when invoked, the gst-launch program spits out some information on stdout which I need to capture in my script before exiting. I thought I could just redirect the output to a file (actually, i'm using a named-pipe), like this...
Code:
gst-launch .... >gstpipe &
Unfortuantely, whilst the stdout information does indeed appear in the gstpipe file, the process list doesn't show gst-launch anymore, but the original script instead. I.e.
This appears in the process list, even after my script has exited, indicating that when invoking gst-launch, the shell is creating a new process, but with the wrong name.
What am I doing wrong here??
Thanks for any help,
Regards

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... (3 Replies)
I have a simple bash script that prints sth every 5 seconds. What I do is the following.

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)

Is there a way to redirect all stdout to a file implicitly - like defining stdout=/home/me/process.log - so that all "echo" commands in several scripts/subscripts are written to that file; instead of having to edit all scripts to redirect the "echo" (e.g. echo 'This is a test ' >>... (1 Reply)
In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)
