Software :: Launch A Batch File With Screen?
Jun 27, 2011
I understand SOME of how to use screen; attaching and detaching screens, etc.
for example:
screen -d -m links cnn.com
Then I can type
screen -ls
or
screen -r
and re-attach to that session.
But what launching a batch file? Said batch file contains 2 commands; a CD command, and a command to launch Python to run a certain Python script.
Whenever I use the batch file as the command for Screen, it always exits and terminates the screen session -- there are always "0 sockets". Even though the Python script in question is very persistent, and runs indefinitely.

I am trying to convert my batch file into a .sh file and i think i have it perfect but it just will not work, so obviously not perfect. This is the code for my batch file.
[Code]....
This works perfectly on my own computer without any problems. I want to host this on my Linux VPS (CentOS 5) and need it to be converted into run.sh. This is the code for my run.sh.

I am logging the output of: top -b -n1 -c so I can keep track of which processes are using how much memory and CPU each minute. When top shows the full command line (-c), the command line text gets truncated at the edge of the screen. This is perfect when running and displaying in a terminal. However, I am sending STDOUT to a file for parsing later and want the full command name logged. Is there a way I can tell top to use a specific screen width? (I know it maxes at 512, that would be fine)
Is there a better way to achieve a similar goal: get periodic stats about which processes are running and how many resources they are consuming?

I want to quickly get to the Root directly (or whatever it's called).This is how I do it now; (the text in bold is what the computer spits out)
me@me-desktop:~$ sudo -s
[sudo] password for me: (then I enter my password)
root@me -desktop:~#
I'd like to just type one the new of the batch file and then hit enter. The batch file would then do the rest.

I'm looking to, all in the course of one batch file:
ssh into a remote computer execute commands (per the batch file) on the remote host.
What options do I need to add to the ssh invocation so that the batch file executes the lines following the ssh invocation over the connection?
e.g., with sftp it's simply adding a -b /dev/stdin and then << EOF at the end; how do I do this with SSH?

I just learnt to convert a video file into mp4 format so I can watch it on my PS3. However, I have dozens of video files from my video cam, and want to convert them all. They are all in the same folder. Please can someone explain how I might be able to adapt the code below so I can convert all my files in a batch. Perhaps keeping their same name or giving them some other name, I don't mind.

I've created a .bat file with this line: start C:USERSPuttyputty.exe -ssh user@server.com -pw password
That opens a putty session and logged in it with the user and password i've already specified. But now, I want to enter a simple command like "ls -l" for example.. How can I do that?
I've also tried plink...The line in that case is this one:
start C:USERSPuttyplink.exe -v -ssh user@server.com -pw password -m UNIX_commands.txt
and in that file "UNIX_commands.txt" I've added the following lines:
cd /projects/test
ls -l
all works fine (the commands are executed) but i can't see the putty session... all i can see is the verbose in my DOS windows of the last line "ls -l"...
The putty session vanishes away. How can I have the session opened and list the mentioned directory.

This is for a live performance type of setup. I have 2 graphics cards. One is attached to 2 projectors, which are what the audience sees. The other has a single monitor, which is backstage. The 'front' graphics card is configured in Twinview, and the 'backstage' one is configured as a second X screen by the nvidia settings control panel.
What I'd like to do is launch my show program from a terminal on my backstage screen, but have it show up on the other X screen, the 'front' one. X is amazing so I'm sure it can be done, but I'm having a hard time figuring out exactly how.
Personal Best for self-solving my own thread question:
Code:
DISPLAY=:0.0; xclock
launches on display 0
Code:
DISPLAY=:0.1; xclock
launches on display 1

I have been running Ubuntu 10.04 Lucid not on a separate disc partition but installed right on my Windows (7) partition. Everything was working fine until yesterday. I restarted my computer and then the system was scanning the disc then suddenly after the disc check, the computer restarted and when it was supposed to launch Ubuntu, the screen went completely white. I tried restarting again, I manage to get to where I choose to boot with Windows 7 or Ubuntu. I choose Ubuntu and the same happens again: white screen. It doesn't go any further than this and the only thing the computer can do is boot with Windows 7. Has anyone had the same problem? Also, is there a way I can access my files (saved in Ubunutu) from Windows? If I can manage to copy these files then I don't mind reformatting the whole disc.

i am wondering if it is possible to do this all i can find with google is idea proposals and brainstorms i know i could make a separate account and call it guest user bu that user would get to keep data/settings where as a guest session places a temporary account in the /tmp folder which combined with a ram disk for /tmp would result in some really fast performance since i use a ssd for / which would make the traditional hdd only used for /var also since /tmp would be a ram disk it would be like the guest is using a live cd with security restrictions and performance enhancements on top of this there would be no trace of the guest on my computer after shutdown

I am on an xubuntu live cd setting up gentoo linux. I use screen to make sure that all my compiling and whatnot runs in the background and I won't accidently exit it. I have a script that I have written that autoruns starting my screen session, whenever I insert my thumbdrive. A seprete script should be passed along to screen telling it to chroot into my gentoo setup. However, whenever I use screen -X ./myscript.sh it says that it is an unknown command. How can I pass it along to screen?

Basically, the problem is, we have a bunch of computers in a computer lab, that we want to students to access, but not modify in ANY way. That includes backgrounds or whatnot. And after restart, any changes they may have made, change back. Also, they can't have read access to the administrator account on the computer.
This needs to give a permission denied, or something:
Code:
cd /home/(admin account username)
ls
The Guest Session is exactly what we are looking for, but try as I might, I can't get it to work. Because, we don't want to have to login as administrators, then activate guest session, just for our students to use the computers. The idea being, we can leave the computers in there, and not worry about the students breaking anything.
One thread I tried was: [URL]. However, using his method, will log the student into the account, and after about 5 seconds, log them back out.
The other method listed lower in the thread,
Code:
/usr/bin/guest-session
Seems to work, but upon logging out, fails to launch the gdm
Only way to restore is restarting the computer.

I just installed Natty, its ok so far. How can I keep applications from launching full screen? I know if I resize the window below 75% or some thing like that it does not start full screen however I need the window to launch at like 85% and not full screen. This is the most frustrating thing I don't know what Canonical was thinking. I put it in if you have to however make it easy to undo..

I've written a script (that doesn't work) that looks something like this:
#!/bin/sh
screen -dmS "somename" somecommand
for i in {0..5}; do
screen -dmS "name$i" anothercommand $i
done
For some reason, if I copy and paste this into a terminal, it creates 7 detached screen sessions as I expect. If I run it from within a script, however, I get only the first session, "somename," when I run screen -ls.
Edit: If the same can be accomplished another way (e.g. with multiple screen windows instead of sessions), I would be open those solutions as well.
