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 | \__\__,_|\_/\_/ |______________________________________________|

Keyboard and mouse 'crash'
by Bev Nicolson 19 Aug '12

19 Aug '12

Every so often (not too often happily) both keyboard and mouse will stop functioning. It seems to happen most often when I plug a camera or MP3 player in. The only way to get them going again is to switch everything off. (If I touch the off button it will shut down in 60 seconds from the shut down dialogue box.) What I'm wondering is, has anyone here come across this problem and is there another, more permanent, solution to it? I would add that I've never had to install any drivers for any such devices, so I'm pretty confident that's not the issue. [Unbuntu 11.04.] Bev.

deb/alien dependencies
by Mark Rogers 11 Jul '12

11 Jul '12

I'm trying to install hamachi [1] on Debian (arm). I want the smallest install I can get away with, but at the moment I'm getting the following dependencies: alien at autopoint bc binutils build-essential bzip2 cpp cpp-4.4 cups-bsd cups-client cups-common debhelper dpkg-dev fakeroot g++ g++-4.4 gcc gcc-4.4 gettext gettext-base git html2text intltool-debian libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libc-dev-bin libc6-dev libcurl3-gnutls libdpkg-perl libelf1 liberror-perl libgmp3c2 liblua5.1-0 libmail-sendmail-perl libmpfr4 libnspr4-0d libnss3-1d librpm1 librpmbuild1 librpmio1 libstdc++6-4.4-dev libsys-hostname-long-perl libtimedate-perl libunistring0 linux-libc-dev lsb-core lsb-release m4 make manpages-dev ncurses-term patch pax po-debconf rpm rpm-common rpm2cpio time It installs and runs OK but I don't want all that stuff on my box afterwards! Seeing alien in the list makes me conclude that this is a repackaged rpm and maybe that's what's causing the problem. However if I try to "apt-get remove alien" afterwards, hamachi gets removed. What are my options to work around this? Unfortunately Hamachi is not free and therefore I don't have access to the source.

Barclays Online Banking
by Ted.Harding＠wlandres.net 05 Jul '12

05 Jul '12

Greetings all! Anyone out there who banks with Barclays and is having problems accessing Online Banking with Linux? I last logged in 6 days ago with no problems. Today, when I try to access it, no login page comes up -- it just hangs forever. So I can't even try to get started! I'm using (an admittedly slightly elderly) Iceweasel 2.0.0.19 of 2006 on a Debian Etch 2.6.18 last updated Feb 2010. Any suggestions most welcome! Best wishes to all, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 12-Jun-2012 Time: 19:00:45 This message was sent by XFMail -------------------------------------------------

Lenovo T520
by Paul Grenyer 02 Jul '12

02 Jul '12

Hi All I'm still having lots of wifi and 3G card related problems with my Lenovo T520 and Linux Mint 13 (I though it was 12, it was 13). Does anyone have a similar machine (or even the same machine) that they're successfully working with? Maybe I could pick your brains at one of the pub meets? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer ACCU Member: License to code.

Open source alternative to full fat Adobe?
by Bev Nicolson 26 Jun '12

26 Jun '12

Evince is great for what it does, imo, but you can't extract pages with it. Does anyone round here know of a good alternative to the full-fat, all singing all dancing but not very cheap Adobe? Does such a thing exist? Bev.

SOund unavailable on Flash Player
by Ted.Harding＠wlandres.net 24 Jun '12

24 Jun '12

Greetings All! Just now, wanting to play a YouTube video, I found that the sound on Flash Player is turned off, and I can find no way to turn it on again. The "speaker" icon in the bottom bar as an "X" beside it, indicating that it is turned off, and I can find no way to turn it back on again (e.g. clicking on the icon, or on the "X", produces not response; and looking into Settings after right-clicking on the Flash Player screen offers no help). However, everything was fine a few days ago, and I'm not aware of having done anything which might cause this problem. Also, the YouTube video is indeed the same one which I had watched a fews days ago with no problem. Can anyone offer any help with this problem?

Wierd hang(s) when using grep
by Chris Green 20 Jun '12

20 Jun '12

Over the past few months I've noticed that when I run grep it sometimes appears to hang, I had put it down to doing "grep -r" down a rather large file hierarchy but now it's happening with a perfectly simple grep:- www-data$ ls *.txt sidebar.txt start.txt www-data$ grep xxx *.txt www-data$ grep fred *.txt www-data$ grep 'CLEARFLOAT' *.txt ... and there it sits, still (like 5 minutes later). The two .txt files are only a few tens of bytes long. It's not using any processor time, it's just stuck. I have just done it again in another terminal window, quotes removed but otherwise the same:- www-data$ grep fred *.txt www-data$ grep CLEARFLOAT *.txt ^C www-data$ ... and with a different user (in the same directory):- chris$ cd /home/www-data/www/wiki/data/pages chris$ grep fred *.txt chris$ grep CLEARFLOAT *.txt ^C chris$ So, what am I missing? -- Chris Green

Getting MAC address in a shell script
by Mark Rogers 20 Jun '12

20 Jun '12

This works: mac=$(ifconfig eth0 | grep -Eo '..:..:..:..:..:..' | sed -e 's/://g') .. but I'm sure there's a better way. Suggestions? Also, if I have something like: echotemplate="This is my MAC: (MAC)" mac=$(ifconfig eth0 | grep -Eo '..:..:..:..:..:..' | sed -e 's/://g') echo $(echo $echotemplate | sed -e "s/(MAC)/$mac/") .. is there a better way to do the substitution in the last line? I can't swap the top two lines around (one is a user-defined setting at the top of the script, the value of $mac is calculated in the body of the script), otherwise I would just use echo "This is my MAC: $mac" .. which would be nice and easy! But I'm using this as a learning exercise. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
