I untar the pack, and launch the application calling a script, from within the untarred folder,

This launches a gui which allows me to setup a case, which needs some setup file, tipically some *.in and a mesh file, tipically some *.msh.
Other mode of executuion consists of calling the setup file as argument to Impact.sh script ( CLI execution mode, for g33k5 )

View 2 Replies View RelatedI recently got a new desktop, and did a fresh install of Ubuntu 9.04 Jaunty Jackalope. The reason I installed 9.04 is because the laptop I have been on for the last 7 years or so suddenly stopped operating with grub updates. I would t urn the computer on and it would never get past the 'grub loading' screen. but thats a whole different story. So I did a fresh install of 9.04 off of a startup disc I made a while back. Then I copied my /home file from my laptop (the old one) and inserted it into the new desktop's /home directory. Worked like a charm (more or less), and all my settings were transferred to my new computer. Desktop, Preferences, Admin stuff, I can't find a problem with it. Now for the applications.
I've tried multiple how-to's but none of them have worked. I found one that told me to do the following in terminal. Keep in mind, although I've been running Ubuntu for about three or four years now, I would still consider myself a noob. Anyway:
sudo dpkg --get-packages <filename><destination>
this left me with a text only file called 'package.selections' I was then to copy this file into the home folder on the new computer and run the following:
sudo dpkg --set-selections <directory>
Up until that last command, everything worked just fine. The list had tons of package titles (none with a .deb or anything though) and their state, got it on to the new computer and ran the code only to get the following error:
dpkg --set-selections does not take any argument
So i ran it without the directory, and it gave me a new line. So I typed in the directory and it gave me the following:
dpkg: unexpected end in package name at line 1
I've tried numerous other commands changing up the syntax as I go, but haven't gotten any farther. My goal is to have all the same applications installed on my new rig without having to go and install all the packages one by one.
I have an application installed under the directory /home/ubuntu/MyApplicationI have a symbolic link on the desktop to a launch.sh script inside the MyApplication directoryLaunch → /home/ubuntu/MyApplication/launch.shI have ubuntu(10.10) running on a usb flash drive. I want to allow other user's to run the application by using the link on the desktop but I want to keep the installation folder private. So the users can run the application but they are unable to view or copy the files inside the installation folder.
View 8 Replies View RelatedI am trying to troubleshoot an application that is generating several segfaults with an error 14, but the application is not crashing.The program continues to run. I would assume I can connect to a running process to debug it, but I'm not sure what to gather. The program has several background processes associated with it so I'm sure I'll need to attach to the actual internal process. Does anyone have any experience in this to offer some insight?
