After running a command that spits out a lot of output in screen. I drop to Copy mode and try to find where the command start. This becomes very very challenging when there are lots of lots of similar text to sift through. Is there a way for me to quickly scroll to where my command starts?
View 2 RepliesI'm trying to use the screen command to start a split screen by default.
I know once I am an in `screen`, I can type C-a S to get a split screen. But is there a way to specify this as an argument to the `screen` command so it starts automatically with a split screen?
I'm trying to setup a webcam surveillance system. Zoneminder didn't work for me regardless of how I tried configuring it, so I gave up and have now settled on a more primitive solution. I've currently got 6 cams and looping streamer (webcam screen grabber) I can grab a picture from each camera with about a 1 second interval. The previous picture is overwritten and using javascript to reload the image continuously in a browser I get the desired "movie" effect I'm after. The problem however is that as soon as I start using streamer on more than two cameras at once I run into this little snag:
Quote:
libv4l2: error turning on stream: No space left on device
ioctl: VIDIOC_STREAMON(int=1): No space left on device
I've been searching around and it seems I need to increase my shared memory. I've done that (tried many different values and "solutions") but the problem remains the same.
My setup is as follows.
1.php (refreshes updated grab from camera 1 every second in the browser)
2.php (refreshes updated grab from camera 2 every second in the browser)
3.php (refreshes updated grab from camera 3 every second in the browser)
etc
etc.
Is it possible to use something like php exec to execute the command that starts 'streamer' that grabs the image from the specific webcam (/dev/video1 for 1.php and so forth) when 1.php is opened in the browser. Is this even possible, or am I just dreaming?

The Minesweeper instance is not tied to the command prompt in any way that I know of, with the exception of Minesweeper's parent being set to that instance of the command prompt. It's different in Linux, however.
In Linux, if I have a console window open, type emacs and press enter, Emacs will open, but it seems tied to the command line. Specifically, it appears that I can't use the command line anymore until that instance of Emacs is closed. Is there a way to replicate the Windows behavior in Linux?
why firefox is not started if I use scheduler command 'at'. I can start firefox from terminal. But when I use 'at hours:min' it doesn't start. I tried 'firefox &' but it doesn't start too. If instead of 'firefox' I use 'mv fileName1 fileName2' the file is renamed as expected.

Like start.sh that does "screen serverapp1"
and stop.sh that does "kill serverapp1"
I already tried something like that, but it didn't work. The kill command only works with process ID's and that one is variable.

I want to monitor my work on the terminal.I know we can use script command.But every time when I start the terminal, I have to type script to start it.I want to automate it. So where should I include this command so that it will start as soon as I start the terminal ?
MY WORK TILL NOW: I have put this "script" command in the .profile.The when I start the terminal, it became an INFINITE LOOP.I am able to "echo".Thats coming only once.....but if I write a "script" command then it is becoming an INFINITE LOOP.
I'm trying to figure out how to operate a rather large Java program, 'prog'. If I go to its /bin/ dir and configure its setenv.sh and prog.sh to use local directories and my current user account. Then I try to run it via "./prog.sh start". Here are all the relevant bits of prog.sh:
[code]...
When I actually do ./prog.sh start, it starts. But I can't find it at all on the process list. Nor can I kill it manually, using the same command the shell script uses. But I can tell it's running, because if I do ./prog.sh stop, it stops (and some temporary files elsewhere clean themselves out).
[code]...
the process is running yet not in any way listed by the system. I can't find it in ps or /proc/, nor can I kill it. But the shell script can still stop it properly. So my question is, how can something like this happen? Is the process supremely hidden, actually unlisted, or am I just missing it in some fashion? I'm trying to figure out what makes this program tick.
I wish to append a text at the start of every line and save it to another file without changing the original file.know the command
For example:
Orignal.txt
a.txt

I'm currently writing a C++ application to manage some screen functions in Debian(server).
However this issue have bothered me for 2 days now...
What I want to do is to send a command to an attached screen which is running.
Used the following command: Code: screen -S screenwindow So I send a command with the -X parameter, which works just fine... Code: screen -S screenwindow -X stuff yes The command I want to send is "yes" and it does appear in my screen window when I attach it.
But the problem is that I need it to submit it... well I need to press "enter" and I've been looking everywhere on how to do that.
Because right now it hangs on a line like this: Code: Something here, do you want bla bla: yes Obviously I could just press enter myself, but the problem is that it's running as a deamon and but it is supposed to do this all by itself .
So are there any way I can submit it?

View 5 Replies View RelatedI am unable to use clear or cls command on bash shell. I have recently installed Cygwin and am using that for practicing unix commands.
I see that I can use Ctrl + L to clear the screen. I created an alias in my .bashrc to do the same as
alias cls='^L'
This is how i defined other aliases e.g.
And they work. Hence I assume cls will work too but this is what I get when I try to give cls on command prompt. Am i missing something? Is there a way to do this?
Then someone suggested, You cannot alias keystrokes to commands or vice versa. You could just alias cls to an echo command: echo -en "x0c"
And I added the following to .bashrc,
Sourced the .bashrc file. No errors but cls still does not clear the screen. Infact when I typed the echo -en "x0c on command prompt as well, nothing happened. What does this command do?
