General :: Make `cp` Choose No When Prompted To Overwrite?

Jun 17, 2011

I have a list of files that I am copying around for various purposes. What my current command looks similar to this:cat list_of_files | xargs -I {} /bin/cp -f {} /destination/dirI am using the full path to cp so that the default alias of cp -i does not take effect. However, when I find a duplicate file, it is overwriting any that have already been copied. What I would like to do is to force cp to not overwrite and not prompt.

General :: Make A Floppy Image And Overwrite The MBR?

Aug 15, 2011

I am trying to make a floppy image with a working file system so that I can test a 2 stage boot loader. When I attempt to mount the floppy and then cp the second binary over to it, mount gets all unhappy. Here are the steps I am trying to use:

dd if=/dev/zero of=floppy.img bs=512 count=2948
mkfs.vfat floppy.img
dd if=boot1.bin of=floppy.img bs=512 count=1

Fedora :: Make Mkdir Silently Overwrite Any Existent Directory?

Feb 19, 2010

I am working on a bash script which among its operations creates directories using the mkdir command. However, when the directory already exists mkdir mentions that in the command line output.

Is there any way I can make mkdir silently overwrite any existent directory? (no messages in the output). For the same price, could it be done with other commands such as cp or mv?

Ubuntu :: Make The Pc Start On Windows Auto, Without Prompting By Showing The Choose System Screen?

Mar 24, 2011

I recently installed Ubuntu in my PC, without uninstalling windows coz it`s not really mine, its my father`s. When he saw the boot (like a month later, he REALLY uses the PC...) he went crazy and instantly ordered me to "uninstall that thing". Of course i`m not stupid to do that after a month of seeing how Ubuntu is... I want to know if/how can I make the pc start on windows auto, without prompting by showing the choose system screen, and when i open boot menu (i don`t remember, but i think its F-eight) i have both choices, so I can keep Linux without him knowing.

General :: OS Overwrite Unmounted Data?

Feb 22, 2011

I have a Debian OS installed (6.0), installed on a single partition, which was running out of space. So I copied all the data in /home to a spare partition, then edited fstab to mount this new partition as /home.

This works fine. But now of course I have the /home data both on the new partition (the one that is now being mounted and used), and also still on the original partition, though this directory is no longer mounted by the OS, so I can't directly 'get at' the data to delete it.

I could easily get into the partition from another OS and delete the unneeded /home data of course but I was just wondering; as this data is no longer 'seen' by the OS, will it be overwritten automatically by the OS when it needs more space, as it does with data that has been deleted from the filesystem, or would it be reserved somehow, still using up space?

General :: Prevent Author New Files Overwrite Changes

Jun 29, 2011

I use software where I have to edit a text file in order to get my custom needs from it. Problem is that when the author puts out an update, it always overwrites my changes and I have to spend hours trying to compare the file, re-edit my changes back in, etc. This happens sometimes as often as once per month.

I've wondered if there might be a linux tool or commands which would look through the new file, then at my old file, changing only the text which already exists while not breaking anything else. Most software authors seem to know how to do this but since mine doesn't, how can I accomplish this on my own?

General :: Command To Overwrite File With Sed Output?

Jan 5, 2010

For example I want a file to be processed by sed, and then overwrite the file with sed's output. I would try this:
sed '<regex goes here>' myfile > myfile
But it doesn't work as expected, instead it empties the file (I am thinking that as the first byte comes out of sed, it overwrites the whole file and sed has nothing more to do). How can I make this work?

General :: Unzip Command: Option To Force Overwrite?

Jan 26, 2010

I am writing a shell script that unzips a ZIP file into an existing hierarchy of files, potentially overwriting some of the files. The problem is that the unzip command asks for confirmation: replace jsp/extension/add-aspect.jsp? [y]es, [n]o, [A]ll, [N]one, [r]ename: y

This is unacceptable for a script.I need an option to force unzip to overwrite the files.I did not find in the man page nor with Google.

General :: Update Error: Two Updates Want To Overwrite Each Others Data?

Apr 23, 2011

I have a Pentium 4 HP laptop with Linux only OS, Xubuntu 10.04 LTS

I hadn't powered this one up in a long time and when I did, of course, the Update Manager informed me there were a LOT of updates (around 400 files) and of course I said OK.

It never quite completes, giving me an error message. Apparently two different packages are trying to over write each other's data.

The two packages that fail to update are

kdelib5-data and gnome-settings-daemon

and I really don't know what to do about it.

although isn't kde one desktop environment and gnome another? And Xfce yet a third?

General :: Windows - Linux: Can't Overwrite Files On Samba Store

Jun 10, 2010

I'm using CentOS 5.5 with smbclient 3.0.33-3.28-el5 (latest version in repo), and I can't overwrite files in my Samba store. I am not the admin for the Windows server that hosts the share, so there isn't anything I can do server side. But I do have write permission to the server. I know the server runs Windows XP or Server 2003; I don't know which. I can delete the file, and then copy the new version over, but I can't overwrite it. Using the cp command I'll get this error:

[jonescb@localhost ~]$ cp foo.txt /mnt/si_storage/foo.txt
cp: cannot create regular file `/mnt/si_storage/foo.txt': No such file or directory`

And if I edit a file on the server using vim, I can save it once, but if I save it again I get this: "/mnt/si_storage/foo.txt" E212: Can't open file for writing This is my /etc/fstab entry for the samba server: // /mnt/si_storage cifs username=myuser,password=mypass 0 0 I can overwrite files just fine on my XP machine. The CentOS box is the only one having problems.

General :: "Login Incorrect" Error After Boot - No Password Prompted

May 17, 2011

I have built a linux image based on kernel The image boots up fine & at the login prompt when I enter the login Id - the
system doesnt prompt for password - instead throws an error message "Login incorrect".

mygway login: admin
Login incorrect
login: root
Login incorrect

From all the search I did, I narrowed this down to be a pam configuration issue. I checked that the /etc/securetty has an entry "/dev/ttyS0" to allow root to logon via serial console - so I ruled out this file to be a cause for that error. Few files that I am not entirely sure are as below:

1) /etc/pam.d/login
sudo cat login

General :: What To Choose For A Saas

Sep 16, 2010

We are starting the development of a project in PHP+MySQL that will become a software-as-a-service.After starting and planning how we would deploy the project, the first thing that came into our mind was: the project will be hosted on our Debian stable server and will contain all of our clients databases and each client folders for the project (and of course, a separate server for backups) and all projects running "under" the same apache and mysql server. This was our preferred approach.

Another friend suggested us -as a second approach for the deployment- that instead of having all projects and all databases running under the same physical server and under the same apache and mysql, that we could build our own "cloud" using something like openQRM and have each one of the projects deployed in a separate "virtualized" server (one virtual server per client) and this way the resources are better balanced and is easier to recover a virtual server if crashed as the backups are made of the virtual servers images. He said that this is a very new concept that is taking the internet services market more and more.

So, we started to research about the "cloud computing" concept in order to have a better idea of this second suggestion our friend gave to us.In terms of performance, it seems to me that the "cloud" approach could consume a lot of moreresources than the first approach ?? and is a lot harder to maintain and extend ??I would really appreciate your opinions and recomendations on which option is really worth for what we are going to offer to our clients.

I assume (as I haven't installed Linux before) there could be a choice of file systems. Is there any recommendation on what I should/could use ?

General :: Which Enterprise IM Solution To Choose

The solution should be capable to use intranet only (no communication should traverse the inernet). It would be of an advantage if it would support conferencing. And if it's possible it'd be fine if it'd be free.

One solution which comes to my mind is jabber, but I do not have any experience with it... what's your oppinion on that? What other solutions are there?

General :: Filesystem To Choose For NAS Box Based On OpenFiler

Feb 23, 2010

I'm a photographer and I have a requirement find a better method of storing my photos other than multiple USB2 drives via USB hubs. Currently I use a Macbook Pro and 6 external drives connected via USB2 or FW800. 3 are a copy of the first three, kept up to day manually by running an rsync backup. I'd like to run a FreeNAS or OpenFiler NAS box using 2TB drives mirrored via software RAID. But - I would like to have the flexibility of also plugging into the drive physically for the faster throughput when necessary. My question is, is there a file system that both *nix and Mac OSX will play nice with?

General :: Choose Distribution For USB Memory Stick?

Mar 29, 2011

I got an 8 GB USB Memory stick wich I want to use, I dont want to install Linux on my harddrive, I want it portable and on an USB stick.

What I need is a distribution thats big with lots of programs and the Ability to Save files and configurations Directly on the USB Memory stick, and it should be able to run apache, mysql,php and java.

I want the USB memory stick to act like a harddrive so to speak.

Also, I already downloaded and tried Knoppix Live CD, but I cant get knoppix 6.4.4 to work, but an older version worked. But its so small, not so many programs. Is there a way to install lets say a DVD version of a distro to USB and make it work like the live version?
