Programming :: Full Screen Java App From Command Line?
Oct 29, 2010
I am trying to make a java application run on a barebone computer connected to a tv screen trough hdmi. I want to make this run as light as possible so gnome probably is overkill. currently I'm running fluxbox but I would like to encapsulate video and some other gui stuff in the program and run it command line(trough startup script.) Another way to do this would be running it when fluxbox starts in full screen. But I really don't know how to do this or where to edit the startup script so I can run it. I'm using ubuntu 10.04 server edition and only installed jre, fluxbox, and of course ssh-server.
I need to execute evince from command line or from a shell script and open it directly in full screen, or start some program for presentation.
I mean:
$ evince (this opens evince) $ evince /dir1/dir2/file.toview (this opens evince and the file.toview but not in full screen) $ evince /dir1/dir2/file.toview 'in mode presentation'
I've just installed java (jre-6u21-linux-i586.bin) on Red Hat 4.4 AS and issued this command to check the java version: java -versionand got :bash :java: command not found
I am currently interning at a place and my job is to essentially learn UNIX. My supervisor gives me problems here and there to help guide me with my learning but for the most part I'm doing this all by self-teaching myself. Needless to say I have run into a few obstacles...for instance-Create a *one* line command that, using tar, will collect the full /usr/local directory (you need to run this as root again) and copy the whole /usr/local structure under /optFor example /usr/local/bin/hello will become /opt/local/bin/hello, etc. I want this as follows:1. /usr/local is collected by tar, but the output of this tar command is its stdout.. what you get from the previous stdout, you compress with gzip and send it to stdout again 3. get this output and decompress with gzip.. get this output and pipe to tar in a way that will extract the tree under /opt.If anyone knows how I could go about doing this, please let me know, or at the very least point me in the right direction. What I've got so far (which could be completely wrong) is:tar cvf - usr/local/ | gzip -c - | gunzip -c - | tar xvf -in theory I feel like this should work (except for extracting the tree under /opt...i'm kinda stuck there)
I have bound over the command line all for my work related jar files to my CLASSPATH and can now execute the command javac HelloRDFWorld.java and there comes noerror messages. I assume javac command can be executed without any problems:
This obnoxious bar has just appeared in Smplayer at the top of the screen. It stays there even when I go full screen. Now full screen isn't full screen and there are black edges on both sides of the screen. I have not be able to figure out how to hide it. I do not need or want this onscreen display. How can I configure Smplayer to make this go away? How can I get my 16:9 full screen aspect ratio back? I have done nothing to mplayer or smplayer as far as editing any or changing any configuration files. I tried several videos and it displays on all of them. It was not there last time I used Smplayer.
I'm using a webhosting server running CentOS, and I'm trying to install GCC to compile Java on the server. Since I'm new to Linux and don't have root privileges, I'm having trouble installing this. I need to install this using command-line. I don't know if I should compile from source (which I downloaded off the "gcc.gnu.org" website) or if I need to install a binary or something. Can I even install anything without root privileges?
I am thinking of appending something to each line in a text file with Java. I prefer not write a new file with content appended from the old one.That 'something' would probably be Time Stamp when the file is created (which is same for each line).I am not sure Java provide some easy way for it or not
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code: #! /bin/bash # #TODO write this for gnome and xterm USAGE=" ${0##*/} [-x] [-g] code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code: gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
I am running a java application on centos. For now I have a gsm modem connected via the the usb cable. Below is the message I get when I type the command dmesg | grep tty
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A usb 2-2: pl2303 converter now attached to ttyUSB0
I have an installation of Maverick using command line only. It switches the monitor to standby after only about 5 minutes. Previous Ubuntu server and command line only versions do this too. Does anybody know where the setting is to change or disable this behavior? Perhaps something to do with ACPI?
While attempting to install an external screen on my laptop I messed up the KDE screen settings and upon reboot I get a command line interface.Which configuration file should I edit to set up my screen so that I get my Debian lenny KDE GUI back?
I was running scripts overnight from the command line (inside Screen on a Linux EC2 instance) and some errors that I was not tracking occurred. I want to "scroll up" or view more of the history in Screen, but I cannot seem to find any commands that will work. I need to see the onscreen output "further up" than I can on my current screen. CTRL + a is supposed to put me into scroll mode inside Screen, but it's not working.
I have used the below command to do that successfully for the previous version of ububunt, but this time I failed to do that with Ubuntu 9.10. I know I can do that manually by "sudo /etc/init.d/gdm stop" command. I try to change the name of /etc/init.d/gdm files, but the problem still exist.m"sudo update-rc.d -f gdm remove"
is there a way to change the gdm login screen (either the background image or the text in the login window) from the command line?i'd like to check several things at boot and report that on the gdm login screnn.
I am having an install problem where the distro I am installing, installed at the wrong screen resolution. The display settings menu doesn't offer the correct resolution so I'm using half my screen real estate.
I'm building a script for my place of employment. The next step in it is checking what the user input was. Determining if they added a part in there or not. The script prompts for a hostname. Hostnames are localhost.localdomain. Now, I want the script to check to see if they put localdomain and if they did, not to add the domain to the /etc/sysconfig/network, but just what they entered. So say the user inputs:
I need to write a script that will take 1 command line argument. The argument will be a username. The script will determine if the user exists on the system and will print an error if it does not. If the user does exist it will determine if the user is currently logged in, if the user is not logged in it will determine the last time the user logged in and display the file in the users home directory that was most recently modified.
I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
I am wanting to write a program that runs a program or command-line. Is there are way of making a program that activates a command-line (for example executing 'ps -a -f' or '/home/shared/fah').
In addition to that, I want the program to do a 'ps -a -f' and put the results in a buff, how could I do this.
I'm troubleshooting a batch of scripts I'm modifying, including an IDL script called by a .csh script. the IDL scripts were provided to me by a coworker and my .csh script is intended to automate a lengthy set of extremely tedious and time consuming processing tasks.
I am currently in the process of debugging, and can't get the IDL to print any messages other than critical failures to the screen. Is there any easy way to redirect the stdout to either a logfile or the screen?
I am taking an argument from the command prompt for my shell script ie $1 and i need to use $1 in my awk part of the script.But it actually doesn't get any value when used in awk. accessing this command line argument in awk?
