Debian :: Use Screen To Execute A File With A Certain Session Name Instead Of Just Numbers?
Feb 11, 2011
I'd like to use screen to execute a file with a certain session name instead of just numbers... or at least have a more permanent name, I'd like to be able to use it all in one command though. So I can put it into a script.Also: is there a way I can remove or change what comes up at the debian login screen so instead of debain 5.0 I can make it say something else? Also when I login the message that comes up is a little annoying, is there a way I could remove or change that too?
I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.
Is there one command that will let me record an entire terminal session (with any possible errors) to a text file while also seeing all output on screen too? I know it can be done for individual commands, but I'm looking to do this for an entire session where the individual commands will be normal (i.e., not piped into tee, etc.). It would be even better if the command prompt is captured too. The obvious utility of this makes me think someone surely has come up with a solution long ago (probably in the 60's).(I'm sure it goes without saying, but subsequent output in that session should be appended to the file. The file should contain the full history, with all output and errors, of the session.)
When I start a screen session over SSH, I can edit and save files from within the screen session before I log out of the SSH session. But after I log out and log back in, I find that the screen session has lost write privileges, so that I can no longer edit or create any files, even within my home directory. How do I prevent this from happening?
Is possible (by root of course) to run a command from console, that will be executed on X-session owned by another user on the same linux box/machine ? Example: Can root open xclock for another local user logged into X11 ?
Can i make a .desktop file taht it executes autostart.sh script or any other script? like xmonad.desktop od dwm.desktop?so that when gdm or any other gui login manager loads autostart apps in xmonad?
I'm not so expert using Debian (3.2.68), especially when it comes to install stuff... I tried to execute for the first time a *.sh 451mb file, but it displayed that:
Code: Select allroot@Poulpe:/home/ambroise# sh gog_hatoful_boyfriend_2.0.0.2.sh Verifying archive integrity... All good. Uncompressing Hatoful Boyfriend (GOG.com) 100% Collecting info for this system... Operating system: linyx CPU Arch: x86_64 trying mojosetup in bin/linux/x86_64 USING
PANIC Initial setup failed. Cannot continue.
Error: Couldn't run mojosetup
It seems that mojosetup is an open software included for all recent GOG games, but maybe it can't run on Debian ? Or could it be more a directory issue ?
I am having trouble writing a script that monitors a text file. When the file contains number 1 (or any other string that is not a command) it does nothing, but when it is something different from 1, it executes that command.
So, there are 2 files: monitor.mon - this is the file that will be checked constanlty; and test.sh - the script that does the job. The monitor.mon file will have its content modified by php. This means a web page will have a form where I input commands and writes does commands in the file. Test.sh will watch when the file's content changes from character 1 to a command, execute that command and write back a 1 so it will not execute it more times.
I tried combining while and if but with no success. Tried reading the file with cat and grep -e but it doesn't seem to recognize when content changes.
i created a /tmp partition amd mounted it like this:" mount -o loop,noexec,nosuid,rw /usr/tmpDSK /tmp" I know i can't execute things in /tmp now but is there a way to execute only one file and no more???
I'v installed wmctrl to have a terminal on desktop and I'v configure it with a script I'v found online.I'v add the script to startup menu interface from xfce (I don't know the us name cause I'v it version on system language), when I shutdown I'v save the session, and on the next log in seems that it is run twice, so if I disable the save session button when I log of but in that case it run in the previous status (dir/position)and I want that it run from startup menu from script file....so when I save the session where it save the status??...how can I skip that it run twice with the script running at startup???
I am trying to execute command mactime in order to control changes made to the file system, but I am getting an error. I am running the shell as root, and it is the first time I run the command in this system - Debian Squeeze up to date. The I/O is as follows:
# mactime 3/1/2011 cannot exec /bin/date: No such file or directory cannot exec /bin/hostname: No such file or directory cannot exec /bin/uname -n: No such file or directory Cannot open /var/cache/tct/data/Amnesiac/body: No such file or directory
The first three lines of output are the ones that are worrying at the moment; I am not concerned with the last. Although error messages suggest the programs date, hostname and uname do not exist in /bin directory, they are available as shown by
I have recently switched to using LXDE on my PC and I am on the whole pretty pleased with it. However,PCMan is giving me a really odd problem. Some of the files/folders are being displayed in the wrong order where they contain numbers. They are being ordered by their first digit not the whole number.
I am trying to write a perl script which will give an interactive session to a user to execute command on the server. I have written a small script to do this :
Code: !/usr/bin/perl -w use strict; use Net::SSH::Perl; my $host = '192.168.1.1'; my $username = 'user'; my $login_passwd = 'test123';
In a nut shell, I have a program called OpenSim which is a 3D virtual world emulator. My ISP provides me with dynamic DNS so I have written a program that compares my external IP to the IP in a file called Regions.ini that OpenSim uses to go out to the Internet. If the IP's are different then I need to change the entry in the Regions.ini file and reboot OpenSim. The program works except for the fail safe I put in in case OpenSim crashes during shutdown which happens one in a while.Here is the code:Quote:
I am trying to execute "caGrid-installer-1.3.jar" file. But its giving me the following error.
Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-6-openjdk/jre/lib/i386/xawt/libmawt.so at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1649) at java.lang.Runtime.load0(Runtime.java:787)
I am trying to extract 2 numbers from a same file and my goal is to print them both in another file, on the same line, separated with a space. I have to do that for 20 files and I would like to have therefore 20 lines like this in the output file. It would look like this :
And I did this by running a bash script with the following content :
Code:
#!/bin/bash ls execution$1$2*.* | while read filename do cat $filename | grep -e "Total aborts:" | cut -d " " -f3 >> abort$1$2.dat done
$1 and $2 are just strings to identify the different files I want to consider in this loop. This script works well to extract a number which is the 3rd field of a line starting with "Total aborts:".Now, how could I change this script to do what I mentioned above (i.e. extracting two numbers from two different lines) ? The second number is the 3rd field of a line starting with "Total throughput:"
When I press )print screen button ) it says ....here was an error running gnome-screenshot:Failed to execute child process "gnome-screenshot" (No such file or directory)
I am working on a project but it consist of a large amount of numbers. I have tried using OpenOffice to produce this list of numbers but it keeps crashing when I reach a certain point. So I was looking for some help. I need to see if someone could either help me with using a script or program to export these numbers into a .txt file or if someone could just make the list for me.
I am looking for a text file that will have the numbers 1000000000 to 9999999999 in order. I understand this is a large amount of numbers but this something I don't have the time to just do manually and each time I try to do it with OpenOffice it crashes around 1009000001. Oh and I need the text file to look like this:
Is there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?
I am trying to find a way to replace a set of sequential numbers in a file with a different sequence using sed. This might be done easier using awk or some sort of bash script, but it seems to me there must be a way to do this easily with sed. Basically, what I am editing is a Cisco switch config. I want to change the sequence of ports to a different numbered sequence. Here is an example of what I am trying to do.I want to change for example, the file:
I ran into it while google Segmentation Fault. I'm writing a simple C program that reads a file that counts each line and numbers it then writes to a file called sdout. I copyed my program mostly from the text book but im still having problems. Heres my code:
am writing a small search program for my class. I have decided to use indexing for my program. Ive researched online about indexing and how search engines do it. If im gonno do that I need to create inverted files to associate files to numbers ( numbers being the index of my paths ) . Now I was wondering what would be the best way to create an inverted file ? I was going to create sql tables using mysql api in C but then again there is no array data type or vectors to store few numbers in a single column in mysql and it is not advised to use Enum or SET
I have thousands files in which there are numbers and a dash followed by file name (which are different from each other), but have the same suffix. I would like to remove all the numbers and dash that precedes the file names.
I'm writing a bash script where I read a text file (containing a column of numbers) and store each line in an array. There seem to be some problems with the whole thing however, but only for some files and not others. Here's what I do:
Code: #!/bin/bash file=time_notOk.txt ### The file with a column of numbers i=0 ### Array counter ### Read the file
Im using an if statement in the bin ash shell and it isnt working.
Code: if (( 5000 > $available_blocks )) then echo "WARNING Disk space low, "$pct_used" is used" fi
I don't think its a problem with the if. When i use that code it creates a file with name of the value $available_blocks instead of using the '>' sign for comparing the 2 numbers.
I have to read a couple of numbers from a random.txt file. In this .txt file there are random numbers. They are separated by a space. Example if you opened test.txt:
test.txt :1 6 1 3 6 8 10 2 4
I would like to read those numbers using CAT and store them into an array:
numlen=${#num[*]} - (must be like this because it is a part of a larger program)
I was doing a tutorial on scripting in bash. I saved my file on the desktop and I cannot seem to get to that file to execute it. Here is what I have been using:
I try cd Desktop says that there is no such directory.
