@scottalanmiller Ok.This work has to be carried by me within two days.I have run the script tommorrow
these are questions that you need your manager to answer before even knowing what the script is supposed to do.

@scottalanmiller Consider this "The mozilla version 31 is installed in the ubuntu machine but unfortunately in one criteria the version updated to 38.So now the script has to run automatically in the system and the version 38 has to rolled back to version 31 only.This is the script to be done for this situation

But what if there is 31 AND 38?

How can they not? Since "present" just means that it has been copied there, having two versions is no different than asking how can two files exist on the same computer. Yet tens of thousands of files exist on computers. Each is just a file. This is why I am saying that your description isn't enough to know what to do. You aren't even installing anything, just copying files, so all you are doing is checking for a file to exist, right?

Ok When two version present means I need to specify the path of the innstalled firefox version.after that this confusion will be finished.

Pretty sure firefox on linux is really just "ran" not installed.. It might be the version in the default path but, you could have more versions.

@thecreativeone91 Ok.How to identify that?

You can't. you'd have to search ever folder for a firefox and then check the version, but then it could still be renamed and break the verification.

You are not installing anything, though, you are just copying files. You are bypassing the installation process creating a much more complicated situation. Since you are bypassing the installation system you can have numerous copies of Firefox, each a peer. One is not more installed than another.

Exactly. It's just a file, not installed the way that he is doing it since the version available through the installer is not the one he can use.

You know that this is the case because you are downloading a copy of Firefox and not running an installer.

Exactly again. Once you don't use a system installer the concept of "installed" because extremely murky.

How did that come from his last comment?
-
I have given the command through which I try to compare the version of the firefox.Whether the command is correct or any correction needs to be done.

firefox -vThis will tell you what version of Firefox you have in your path, nothing more. It doesn't tell you how many versions there are, what versions people are using, etc.

So we've confirmed that you are not installing Firefox at all. Have you read what we've been telling you?
You always seem to skip the information that we say and ask the same questions over and over again after we've explained that the question can't be asked. I understand that it is tempting to just skip comments that you don't understand, but you can't do that. Figuring out what the installed means is pretty important here. You can't just ignore all that we have been telling you.

You are not checking on what you were told to check. This is exactly what I've been telling you from the beginning. You have not been given instructions with enough information to know what to do. Either you need to get clarification or you need to make a judgement call.

To delete Firefox, you delete it. It is that simple. You use "rm" like deleting any other file because when you copy, instead of installing, Firefox, it is just a file. So just remove it.
