UNIX for Dummies Questions & Answers

Hello,
I'm trying to find the version of Firefox that is on my server. Normally I do this.

Code:

> firefox -version
Mozilla Firefox 10.0.7

The issue is that this version of Firefox, is Firefox ESR 10.0.7. I need to be able to see, from the command line, the version of Firefox and if it is a ESR version.

Thanks

Did you try what:

Code:

what /usr/bin/firefox

assuming /usr/bin is the location of the executable

What? Isn't "what" in very limited use? I never heard of it before.

-------------------------

What output do you get from firefox -v command?

If you can't figure it out, maybe just uninstall and reinstall with ESR. It should not take long to install.

Or look in directories where it is installed. Could well be a readme file with the needed information.

From within firefox, you can just check if app.update.channel in about:config is set to "esr". I'm not aware of any way to query about:config settings from the command line, but perhaps you do.

Thank you for replying.

jim mcnamara,
what is not a command on my system

hanson44,
I have provided the the output from firefox -version. I didn't see any read me file.

alister,
The point is to do this on the command line.

Anyway, the reason I want to do this, is so I can wright a script to see what version of Firefox is running. This is because I do a lot of server hardening and to fix certain CVE hits you need to upgrade to a certain version of Firefox.


For example to fix CVE-2013-0787 you need to have Firefox updated to one of the versions below.
Firefox 19.0.2 or later
Firefox ESR 17.0.4 or later

I'm sure you can now see my issue.

Yes, I gathered that and even mentioned it in my post. I shared the information about app.update.channel in case you knew how to query about:config from the command line but were not aware of that particular setting.

What about trying this:

Code:

$ grep -r "app.update.channel" /usr/lib/firefox
/usr/lib/firefox/defaults/pref/channel-prefs.js:pref("app.update.channel", "release");

?
