View 3 Replies View RelatedI have an external hard disk with lots of big files and a lot of small matlab script files .m. I would like to grab all the files inside that harddisk that have the .m extension or the *.mat file extension (both are matlab files). Of course this is a
-first-find the *.m files script and
-then copy the files into the hard disk.
What I do not know is how I can also keep the structure of the folders containing the *.m and *.mat files when I will copy them in my local hard disk. As this external hard disk contains 2TB of data it is not possible to copy all the files first and then remove the unnecessary. So I have to find and copy only the files I need but with also keeping the tree structure that the external hard disk has.

View 2 Replies View RelatedI've set up my parents' machine running KDE 4.5 and want them to use the Gwenview import function from the Device Manager popup when transferring image files off photo CDs or other inserted media, since it's the easiest method for them to comprehend. All the files on their photo discs are r-xr-xr-x by default so they're unable to rotate or modify the images once copied to their hard disk. I want to set one specific images folder on their system to automatically force any files placed there to be rw-r--r-- (and rw-rw-r-- for another shared images directory elsewhere). It seems that umask won't work since that can only take permissions away and not add them, and I'd rather avoid getting into messy ACL configuration. Is there a way to achieve this either generically or some hidden config in Gwenview itself? I use KRename myself for such tasks but this is way too complex for my parents to understand so I need something that works without them having to do anything.

I want to search an entire subtree of /, in the file system, for all files, with extension html, created on the hard disk. In addition, these have to be the last five created. I think I could split the problem into two parts: (a) Forget about the last condition. Then this is a job for the find command. (b) Sort the output of find using the date as the key, then use 'head' to print the desired output. But even two such simple steps are enough to justify the writing of a shell script. And here lies my weakness.
My script writing knowledge is rudimentary. What's the final purpose? Well, I lately saved four or five LQ pages onto disk containing information I consider valuable to me. But I don't exactly remember where on the disk. Then: either the problem posed is really of a very simple nature or it is not, in the latter case a script being mandatory. One of the algorithm drawbacks (the one described above) is that find may be running a great deal of time. My machine resources (RAM and CPU speed are low) are scarce and there possible are a large number of HTML files on the disk.
I have this unique situation, I think. My TV plays certain files only through external USB storage. My Ubuntu server stores all of these files on local hard disks. I do not want to buy an external hard disk and then keep moving it between both. Now, strange as it may sound, is it possible to somehow connect my server to the PC and expose a given local hard disk connected to the server, as an external USB drive to the TV?

I am currently using opensuse 11.2 with kde 4.3.1. I am having a problem when I connect my samsung R450. It will not mount or show up as a usable device in either Dolphin, Amarok, or on the device notifier. I have tried manually mounting but I get an error saying it cannot find such device. I did not have any issues using it in 11.1 with KDE 4.2. It is being recognized by my system, but not allowing it to show up as a storage device or being mounted.

When I shut of the usb mass storage on the samsung R450 it switches to modem and is properly detected and usable as modem by my system.I don't have any other problems with other usb devices, such as a digital camera or flash drives, so I don't know if I just missing a system setting or configuring something wrong.
I just discovered that inserting any USB drive causes an immediate hang of the system. The keyboard caps lock and scroll lock lights blink. Only recourse is to power cycle the system. This is after installing Kubuntu 9.10 in January, I don't believe I had occasion to insert a USB drive until tonight. 100% reliable. No entries in logs, presumably because it hangs the kernel when it happens. The /var/log/kern.log file has been corrupted due to file system damage (1+ sectors of some other file inserted into chain) and probably other files as well.
I've not had occasion to report other bugs, but I've found no way to report anything other than application bugs. I tried using "ubuntu-bug kernel" which helpfully said there was no such application as 'kernel' and has been busy "collecting problem information" for the last half hour or more. Somehow I don't think its ever going to finish.
The crash only happens when booted into Kubuntu 9.10. If I boot off of 9.04 then USB drives work fine. Both USB drives I've tried reliably produce the crash. One is a random cheap USB thumb drive (imprinted "Cisco"), the other is a 16GB Corsair Voyager.

Just to be sure I tried the same thing with FreeBSD, though I knew from past experiences what to expect from it. It just worked(tm) flawlessly, but I'd rather not keep FreeBSD just for the sake of one device I can't seem to get working with Linux. All I can guess it must either be a kernel bug that has persisted for far too long or a faulty udev rule.
steps to block usb mass storage devices in linux
View 2 Replies View Related* I am implementing mass storage device on a test board.
* It contains NAND flash.
* Using corresponding "udc driver" and "g_file_storage" I could make my test board enumerate as mass storage device on my Linux machine.
* my 16 MB pen drive (test board) is now ready for read/write.
But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.
Here is the error I get on my test board :

I am so completely frustrated with this and can't seem to find any solid answers. I have a Google Nexus One phone. I want to also use it as a portable music player. I can find no player for Linux that can do ALL of the following:
- copy music
- transcode when necessary
- transfer cover art in appropriate format
- transfer playlists (music files AND .m3u playlist files)
Banshee is the closest, but it is so painfully slow, has many problems with tags and also doesn't transfer playlist files. Banshee advertises support "out of the box" for this device. I've tried overriding with an .is_audio_player file, but it is ignored. Rhythmbox will transfer song files and transcode as necessary, but no artwork, no playlists. Exaile doesn't recognize this device for some reason.
How does the read & write request from a command prompt go to usb & retrieve the file ? When a read request is given , I/O manger sends the request to file system manager (FSM) and from FSM to mass storage device drivver and from there to mass storage , is this right in Linux ?

Since I use openbox with some packages from Xfce4 (mainly for convenience) I get most stuff "for free" as it were when using openbox, but I can't figure out how to mount android devices in a simple way. I can either do it manually, or install some other file manager that has this capability. This leads me to my question, I've noticed that if I install Nautilus, which automatically mounts android devices OotB, I get this functionality in Thunar as well. This leads me to believe that there is clearly a dependency package of some kind installed when running apt-get install nautilus that enables it, It'd be great to get this functionality in Thunar without having all the nautilus packages just littering about for no good reason. the required package is gvfs-backends, which I should have realized when I was unable to browse smb:// addresses. You forget a lot when you only make a fresh install once every 2 years or so.

What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed.

Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

View 1 Replies View RelatedI feel there's a bit of a misunderstanding going on between C++ and me...My problem is that I have a deque of pointers to a class, and create objects then add them to the deque in a for loop. However, the destructor is called on the object as soon as the loop quits.
Code:
This prints:
Code:
Now, if I change the deque from deque<Test*> to deque<Test> then it works fine - I get:
Code:
However, I can't do this with my actual code, because I am creating a deque of pointers to an abstract class, so it won't let me instantiate the class. (This is all so that I can take advantage of polymorphism, and call functions on a set of similar objects without worrying what type of object I'm dealing with).
So, I suppose my question is: what is the correct way to create that deque of pointers to the abstract class? I don't seem to be barking up the right tree currently.
i have an old copy machine (canon gp225). the hard disk makes a whistling noise and i suppose it is just a question of time when it will bust.i do have some stone-aged computers here and i think i could use one of this hard disks as a replacement.how do i get the operating system (probably unix/linux or similar) plus the content of the boot sector plus the software on this new hard disk? i think if i could do a one-to-one copy i might have a chance that i could replace the old hard disk and it will work.
