Add right-click virus scanning capability to Nautilus

[robert_pectol]

With this script saved in ~/.gnome2/nautilus-scripts, you can scan files or directories for viruses by simply right-clicking on them in Nautilus and selecting this script from the, "Scripts" dropdown menu. It relies on Clam Anti-virus which can be easily installed by doing, "sudo apt-get install clamav" in a shell. Simply copy the code below, into a text file and save it as, "virus-scan" and make it executable (ex: chmod 755 virus-scan). Again, it needs to be located in your ~/.gnome2/nautilus-scripts (dot in front of 'gnome2') directory. Anyway, here's the script:

Deleted!
I edited the original post to include the info contained in this one! :)

Good, thanks!
It works even for folders.

[robert_pectol]

You're welcome! I'm also working on a file encrypter/decrypter script for Nautilus. It uses GnuPG. If there's any interest in such a script, let me know and I'll dedicate some more time to it to get it done sooner.

[Rob2687]

It gives and error...

'Error: Can't access' what ever file/folder I'm trying to scan

edit: It only does that when scanning files on the desktop.

Yep, appart from that issue it works like a charm.

Thanks for the howto.

C'mon, let's see it....

[robert_pectol]

Thanks for letting me know. It was a minor bug and I've addressed it with this new version. It seems to have been an issue with the script knowing the full path to the directories/files to be scanned, and getting that info from Nautilus. So, I've made a couple of changes to the script to do that. I've tested it here locally and so far, it appears to be fixed. Give it a try and let me know. If you can break it, I'd like to hear about it. That's how these things get ironed out! I've replaced the script on the original posting with the updated version. If the script didn't get pasted properly or you'd like to download it directly, it is available here:

[dcstar]

Good stuff, thanks for doing it!

[bscbrit]

Rob. Thank you.

Having looked at the code I realise that I could probably have written it myself - but I didn't and you did! Good effort. (perhaps I might even try some of my own)

[robert_pectol]

You're welcome!

[Bloot]

Thanks for fixing the bug!

[Danielle]

thanks for the script, robert :D can't you just edit your first script from post#1 so it works? i ended up having to save it twice, not that i care, it might have taken me abit longer to write the script :razz:

it's really good thanks.

i think it would be perfect. does it use a strong algorithm? it's not important i can't see my Mum taking an interest in breaking encryption keys. i still have to do her emails :rolleyes:

[robert_pectol]

In regards to my mentioning of a file encrypter/decrypted script for Nautilus which I've been working on...

i think it would be perfect. does it use a strong algorithm? it's not important i can't see my Mum taking an interest in breaking encryption keys. i still have to do her emails :rolleyes:

Yes! It uses GnuPG. See their Website for more info:
http://www.gnupg.org/(en)/features.html

The script is about finished but I'm holding off from posting it until I can have a chance to fully debug it. I'll post it to a new thread when I release it.

I'm glad you like my virus scanning script! By the way, I have removed the original script from the first posting. Initially, I chose to leave it intact for the sake of thread continuity but I'd rather be certain that folks have the fixed version. ;)

[robert_pectol]

Ok... I've posted my file encrypter/decrypter script for Nautilus so it should show up in the forum sometime soon. However, for the truly impatient, it can be downloaded here:
http://rob.pectol.com/myscripts/encryption.sh.txt

Enjoy!

[viscount]

Thanks Rob,
Just found these, looks pretty good!

How do i install this??? How do i get it in gnome2??

In your home directory you have dot files that are hidden. If you open up your home directory in nautilus and hit ctrl-H it'll show you the files.

You pretty much have to save his script in a text file. I called mine clamavscan.

You just copy that text file you make in to the directory he specified, the hidden one with the '.' in front of it.

The last thing you'd have to do is right click that script file and go to properties/permissions and make it executable.



robert_pectol: I dig this script man! This will be nice to run before I share files to my windows friends at lanparties and what not. I added you to my forum buddly list. :)

[Gooks]

How do i make it save in that DIR?

[smack]

How do i make it save in that DIR?

If you were using gedit it'd ask you for a save location when you save a new file. You could also just save the text file on the desktop and drag it to the right place.

Congrats to Robert Pectol for this handy little right-click menu tool in Nautilus I'd been missing since Windows.
ClamAV runs slow compared to what I've been used to but that's no criticism of you, I'm sure it's the folks who coded the ClamAV scan engine.
When I Save As your script in gedit, choosing Home directory, it got buried in /root and had to do a GNOME Search for Files... to find it and copy it over to the proper place in my ~/.gnome2/nautilus-scripts directory.
Perhaps someone can teach me what I did wrong so this won't confuse others.

It's guys like Robert that make Linux inebriating to newbies. Happy New Year all!

Thanks a bunch! I don't get worried much about virus problems with linux-but hey-you never know-better safe then sorry!;)

I am new myself but, I am learning. You could have made the script in your home directory and then moved it to the proper directory, or you could have cd directories first and then opened gedit and done it all there. Either way is fine. Knowing the people on this forum though, there may possibly be some space-age way of doing it but, that's why I'm here--so I can learn from them.:p

[daibak]

... You could have made the script in your home directory and then moved it to the proper directory, or you could have cd directories first and then opened gedit and done it all there. Either...

I've learnt my lesson, thanks to rjwood. I should have learned this by now!

username@ubuntu:~$ cd ~/.gnome2/nautilus-scripts
username@ubuntu:~/.gnome2/nautilus-scripts$ gedit
username@ubuntu:~/.gnome2/nautilus-scripts$ ls -a
. .. clamavscan testerTOsaveas
username@ubuntu:~/.gnome2/nautilus-scripts$ rm testerTOsaveas
username@ubuntu:~/.gnome2/nautilus-scripts$ ls -a
. .. clamavscan
username@ubuntu:~/.gnome2/nautilus-scripts$ cd ~
username@ubuntu:~$


To any other newbie out there, as I'd already saved Pectols' script properly as 'clamavscan' in the correct directory this was just a test to do things properly. That's why I deleted empty 'testerTOsaveas' gedit file same folder.

[robert_pectol]

Hi guys. Thanks for the kind words! Probably the easiest way to get the script downloaded and saved to the right location is to do the following:

1. First, to get to the correct location, open a shell and type, "cd ~/.gnome2/nautilus-scripts"
2. Next, to download the script, type, "wget http://rob.pectol.com/myscripts/vscan.sh.txt"
3. Then, to rename it to your liking, type, "mv ./vscan.sh.txt ./vscan.sh" (or whatever you want to call it)
4. And finally, to make the script executable, type, "chmod 755 ./vscan.sh" (or whatever you named it in step 3)

That's it! No having to open it up in an editor at all! ;)

With this script saved in ~/gnome2/nautilus-scripts, you can scan files or directories for viruses by simply right-clicking on them in Nautilus and selecting this script from the, "Scripts" dropdown menu. It relies on Clam Anti-virus which can be easily installed by doing, "sudo apt-get install clamav" in a shell. Simply copy the code below, into a text file and save it as, "virus-scan" and make it executable (ex: chmod 755 virus-scan). Again, it needs to be located in your ~/gnome2/nautilus-scripts directory. Anyway, here's the script:


Removed! Please use the updated one listed a few posts below!

Enjoy!


Excellent, thank you. :p

[robert_pectol]

You're welcome! :)

Thanks for the script, very handy.

[faizan]

thanks for this robbie.. peaceful and handy!

[Pretzal]

nice script... Newbies like me really appreciate this kind of stuff. Thanks

[robert_pectol]

I'm glad you all found it useful! Thanks for letting me know.

[ifyc576]

Thank you for the script. It worked fine.

I have one question; can you select more than one file to scan at a time? I'm only able to scan one file at a time, when I select multiple files ClamAV seems to ignore anything past the first file.

Thanks Again!

Where is the updated version of this script???When i run this script i get an error how to fix it??
