Shell Scripting to be done for verifying the software version and also not to update

do. So since you haven't decided what it will do yet, how can we help you do something?
Please wait?
Sure, just sit down and figure out the goal. What do you want the script to do. We can help you once you know what the goal is.
And whatever you do, stop using the word "installed" because we are not dealing with software installation here and this is throwing you off considerably.

@scottalanmiller Please read the information and if information is not relevant means please inform me.
My overall goal is to write the script for the ubutu 14.04 LTS 64 Bit OS.
The script has to check the version status of the firefox and java .
The overall aim is that the firefox and java has to be present in the specific version at Ubuntu.
The auto update will be stopped for firefox by GUI.
If the firefox or java version updated after this means the script should be runned automatically to uninstall the newer version of firefox or java from the machine and then the specific version Firefox 31.0 and java 1.7.0_65 needs to be installed at the system in background without the user interference.

So answer the original questions:
- Are you looking to see only that the right version exists?
- What do you want to do about other versions?
- How do you want to define the right version being there?

You are back to using "install" again. You can't uninstall or install, you learned this over and over already. Why do you keep reverting to these terms when they don't apply here and are very much causing you to be confused?
-
If you want to remove a version that is not the correct one, you delete it. In Linux we delete with the rm command. It's that simple.
-
@scottalanmiller Yes.I am looking to see only the right version.
Other version should be exist in this system if exists means it should be automatically removed from the concerned path automatically
.I define the right version is there by comparing the version present at the path where the software is present. -

How do you plan to look for other versions?
-
@scottalanmiller In my test machine the firefox updated automatically to 38 version.This was happened after stopping updates at GUI of the firefox.So only I am trying to remove the other version from the system.

That's an odd definition. Doesn't really match what you state that you want to do. Presumably if there were multiple versions or different versions present they would be at different paths.
This implies the opposite of wanting to know if there are multiple versions.

Did it change the path?
-
@scottalanmiller No the path was not changed.

Okay, so if the goal is to make sure that the binary at the one specific path has not changed versions is a bit more clear of a goal.
-
@scottalanmiller I went through the same set of instructions that he used. And when you run the Firefox v31 binary, it automatically updates to the latest version (although I did not run the application as root, so I am uncertain how it did this, lol).

Likely it does not install as root or it does not set root only permissions for updating.
-
I understand the updating issue and why he needs to stop that and monitor it. It's how does he want to deal with lots of other issues like people downloading their own Firefox or running other instances. That's where the questions are.
-
@scottalanmiller In my VM, I extracted a firefox-31.tar.bz2 and moved it to /opt/firefox ... and then as my normal user, I ran firefox, and it updated anyhow.
But I found there is a setting in the channel-prefs.js file you can add to disable the automatic update.

Yup, he had determined that you could do that, I believe. Now he is just required to monitor it too.
You could also use the filesystem to stop updates as well.

My firefox opens only 31 version but the GUI of the mozilla firefox is not available and I need to go to terminal to open the mozilla.Why?

That's really a new question and not related to the original. I would open a new thread for that.
Is the issue as simple as you don't have an icon for it? How have you tried starting from the GUI?

This is because you're running a version you didn't install via apt-get. You'd have to put all the right executables in the right places manually for this.
