Renaming of files failing
by Chris Walker 17 Dec '12

17 Dec '12

I have a directory full of files and sub-directories which I've pulled from an emulator. But it has extra filename extensions on it. I would like to traverse this directory, stripping off the extensions and so I've been trying to write a script to do it but it's failing. An example of a file is this :- lamborghini miura_1024.jpg,c85 and so there, I'd like to remove the ,c85. But a bigger problem is where I have the odd file which has a numeric extensions such as .;1 and that's where I struggle. How do I do a substitution in my script to cope with things like that? I've been reading things like this - http://www.cyberciti.biz/tips/renaming-multiple-files-at-a-shell-prompt.html and http://www.unix.com/answers-frequently-asked-questions/13774-unix-tutorials… but I'm still struggling. Can somebody point me in the right direction please, even if it's towards the door ;-) -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

WiFi range, what am I likely to get outdoors line-of-sight, without special equipment?
by Chris Green 26 Sep '12

The subject says it all really, what sort of range is one likely to get outdoors with WiFi? It's basically line of sight, base station is in a shop, my WiFi router will be sitting in a window maybe 200 meters away. Do I have any chance of it working? -- Chris Green

Catch 22 situation when disk gets full - how to solve?
by Chris Green 23 Sep '12

23 Sep '12

I have a sort of Catch 22 situation on my little eeePc. It has tried to update kernels automatically and, after a few months (it's on our boat doing monitoring) it has run out of disk space. It still runs OK and I can ssh into it. It has quite a long list of old kernels installed but I can't delete them to make space because it has half an update of the latest kernel:- So when I try and do anything with apt-get I see:- root@eeepc:/var/lib# apt-get remove linux-headers-2.6.32-39 linux-headers-2.6.32-39-generic-pae linux-image-2.6.32-39-generic-pae Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies. linux-headers-generic-pae: Depends: linux-headers-2.6.32-43-generic-pae but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). So how do I uninstall all the old headers etc. so that there *is* space to do things? -- Chris Green

Hi folks, Excuse the flagrant abuse of this mailing but I feel the crossover of interest is worth it. The first Norwich Maths Jam (see http://mathsjam.com) begins tomorrow evening (Tuesday 18th) at 7pm in The Reindeer pub on Dereham road; coincidentally a previous haunt of the ALUG pub meet :) If you fancy coming to a pub and being geeky in a mathsy way, come down! Remember kids, beer + geekery -> fun. Steve

apt-get problems
by Greg Thomas 16 Sep '12

16 Sep '12

I just tried upgrading from Ubuntu 10.04 to 12.04.1 (i.e. from LTS to LTS). It failed. The error message I'm getting is: An unresolvable problem occurred while calculating the upgrade: The package 'update-manager-kde' is marked for removal but it is in the removal blacklist. Google suggests that "apt-get remove update-manager-kde" should fix it [1], but that's giving me the following; Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libasound2: Breaks: libasound2-plugins (< 1.0.24) but 1.0.22-0ubuntu6 is to be installed libglib2.0-0: Breaks: gnome-control-center (< 1:3) but 1:2.30.1-0ubuntu2 is to be installed Breaks: gvfs (< 1.8) but 1.6.1-0ubuntu1build1 is to be installed libgnome-keyring0: Breaks: gnome-keyring (< 3.0) but 2.92.92.is.2.30.3-0ubuntu1.1 is to be installed libpango1.0-0: Breaks: plymouth (< 0.8.2-2ubuntu19) but 0.8.2-2ubuntu2.2 is to be installed ppp: Breaks: network-manager (<= 0.8.0.999-1) but 0.8-0ubuntu3.3 is to be installed Breaks: network-manager-pptp (<= 0.8.0.999-1) but 0.8-0ubuntu3 is to be installed E: Broken packages Have I completely hosed my setup, and is a fresh re-install due? Or is there a way around this? Thanks, Greg [1] http://www.hoaglun.com/blog/2011/5/8/ubuntu-1010-1104-upgrade.html

Default browser chooser script
by Mark Rogers 13 Sep '12

13 Sep '12

For day to day use I tend to use Firefox, and that's my default browser. That's more through "habit" than anything else and I frequently get frustrated by the amount of RAM its using etc. Occasionally I'll fire up Chrome or Opera, and one day I'll probably switch allegiances. In the meantime, what annoys me is that if I have (say) Chrome open and click on a link elsewhere (eg in an email) it'll open Firefox because that's my default browser. I'm sure it would be possible to write a script that checks to see if any browser is open, and sends the request there, only actually starting the default (Firefox) if no browsers are open. [Actually I think this ought to be the default behaviour for a range of apps; if I have a media player open don't open a different one if I double-click a media file, etc.] Any suggestions for where I should start? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Running vnc server on startup
by John Woodard 12 Sep '12

12 Sep '12

I want to run a vnc server on startup as a user rather than root and seek opinion to where the best place to put the command tightvncserver :1 -geometry 1280x1024 -depth 16 -pixelformat rgb565 etc/rc.local cron job? Not sure here really if it needs to be before login so thought it prudent to run as a user. Cheers, BJ
