I want to know if it's possible to run software that has been downloaded from the internet. Ubuntu does not allow that but is it possible to set the executable permissions required for ? I recently downloaded software but it wont work due to this reason. Does anybody know of a way?

There is a script which just adds extra lines to my /etc/hosts file to enable local development. Since it's pretty useful, I decided to keep it in a gist. When one of my friends downloaded the shell-script, changed the necessary permissions and tried to run it, it failed. The error shown is:  $ ./dev-mode : No such file or directory  Even though the script runs perfectly file on my computer. The /etc/hosts file exists in both our computers, the permissions and the owners are the same. Every thing is absolutely similar. Then he made a new file, copied the contents of the script to the new file, and changed the necessary permissions, and it RAN! To my eyes, there is no conceivable difference between the two files, but a diff does that they are difference, but doesn't highlight any line or any character... Nothing. The permissions are same, etc. Does ubuntu treat downloaded files somehow differently, and stop it from running? Absolutely same files, one runs and the other doesn't

Hi I'm new to ubuntu world. I have few questions about the software installation in ubuntu:   What's the difference between installing a software in ubuntu software center and command line? Why some software I installed with command line can't be searched in software center (press the window key)? What are the correct commands to install a software from command line so that I can search them? I backed and restored up my system once but some commands worked before (like "subl") don't work after restoring the system.   I think these questions are about $PATH somehow but I can't find some material about this. Any extra material would be appreciated. :)

I am trying to run an executable file from a network drive on Windows 7 Professional (64-bit) in order to install a program, but, each time I try, it doesn't run and the following message appears:  {path-name} The specified path does not exist. Check the path, and then try again.   I am definitely connected to the network drive as I can see all of the directories and files, and can even open non-executable file types. Also, I am fairly confident that this is neither a firewall nor a permissions issue.

Is there any way that I can force a program that normally requires administrator privileges (via UAC) to run without them? (ie: no UAC prompt and no system-wide access.)  Added: Without modifying the executable itself.    In spite of James's answer, I have found a few ways that it can almost be done:   By modifying the executable I can remove the trustInfo entry from the manifest (or the manifest entirely, so I can use an external one), allowing the program to start without UAC. Unfortunately this modifies the executable, so it exits shortly after due to an internal checksum test. By using Process Explorer I can launch it as a Limited User. However this seems to limit it significantly more than I would like (it runs like Protected Mode IE and so can access significantly less than what my standard un-elevated user can).

I am a novice at Ubuntu (12.04).  I have it on my netbook which I use mainly for surfing the net, learning python and remote desktop into my work computer.    Do I need to enable a Firewall type software?  If so, what would you suggest, and what are sensible default suggestions?

Ok, I was kind of surprised that this hadn't been asked here before, but maybe it's too technical for this site. You guys decide.  I've heard lots of different stories about setting up Wine on Ubuntu, WineTricks, PlayOnLinux etc., but never a 'This is the best way to do it for Steam and Steam games' thread.  So has anyone had any real success getting their Steam games to run on Ubuntu through Wine or something similar? If so, could we get some specific steps?

I am curious about how do you protect your software against cracking, hacking etc.  Do you employ some kind of serial number check? Hardware keys?   Do you use any third-party solutions?  How do you go about solving licensing issues? (e.g. managing floating licenses)  EDIT: I'm not talking any open source, but strictly commercial software distribution...

I downloaded VirtualBox OSE from the Ubuntu Software Center but it seems that that version is limited. I prefer to have the complete version and don't really care if it's closed source or not.  Can I install it via a terminal or do I have to download something from a website?  I don't know how to install software I download from the web. So far I've only used the Software Center.

How do I select which server Ubuntu will get it's software and updates from? I know how to find the  on the web, but not how to use them.

If the which command is not available, is there another 'standard' method to find out where a command's executable can be found?  If there is no other 'standard' method available, the actual system I face currently is a bare Android emulator with an ash , if that means anything.

I have been reading here (in superuser) some questions about the necessity of antivirus software in Windows and some doubts arise.  As far as i know (and imagine) virus software can only be harmful if I download any type of infected executable file and then I RUN IT. I mean that if i have the infected executable in my desktop but i leave it there for years without clicking it, I won't be in danger...  My question is: How can i be in danger browsing the so called "malware pages or sites"??.  If i am just browsing an "infected site" how could I be affected by a virus. In any moment the browser is asking me for the permission to download "something", so how could it be?? Although i don't give permission to the browser to download 'something' is data being downloaded to my computer?? Its some kind of cookie?   I will ask in another way... What is the level of riskiness if i get infected in a malware site compared with the level of an executable virus??

How can I run a program on a remote Windows PC in our network without the need of killing an existing remote-desktop-connection? I only need a command line for running the program and getting its results. Thank you!

What are ways to install/uninstall programs in Ubuntu. I will mention only .deb since it is the official package format and for example installing a .sh or .run program can typically be as simple as (In latest Ubuntu) ./program.sh or sh program.run.  Also note that am talking about HOW to install packages IN Ubuntu, not talking about downloading a new installer (Like some Super Cow Software Center Duke Nukem version from sourceforge or something). Only tools that already come in the repositories (In any of the 4 standard ones, main, universe, restricted or multiverse).  Take into consideration all GUI and terminal ways of doing it, with basic format of doing the installation. With this in mind I am talking for example about Software Center, synaptic, apt-get, aptitude, dpkg, etc... a way to show all tools that are available in Ubuntu to install deb packages.  NOTE - Forgot, this should be Community Wiki since it will have all ways a user can install/uninstall something. Like a friendly guide on doing that.  UPDATED question to remove the confusion some are having about sh/run files.

Richard Stallman states that Ubuntu "has installed surveillance code". See:   Is this true?   I agree with him that "Any excuse Canonical offers is inadequate....".

I know I can check the currently installed non-free software with the following command (assuming aptitude is FOSS):  aptitude search '?installed (?section(restricted) | ?section(multiverse))'   And I can remove the "restricted" and "multiverse" sources (and not add any PPA's) to keep that list empty. I'm assuming from this point, whenever I apt install something, that something is either in the allowed sources or it is not found.  Is this enough? Does this make sure all software I'm running (in Ubuntu) is open-source?

I've been building my own Linux distro, and I've stripped the binaries, etc. The system won't use GCC or development tools, as it will be a Chrome kiosk, so it would greatly help if I could strip down the system...  I was wondering, is there a way that I can delete all of the unused system files (like binaries, etc.) by watching what files/libraries are used during runtime? Maybe another method is preferred, but is there a way to accomplish something like this?
