Is it possible to make an ISO of the distribution already installed? Well actually, I have made various changes according to my choice and don't want to do them again if I have to reinstall.
View 14 RepliesI have C in a Nutshell but I'm learning Bash right now. I've gone through a lot of LFS, but didn't complete it. I'm still learning about symbolic links, hard links, libraries, and this sort of thing. I'm wondering about quite a few things at this point. How the hell can anyone make a distribution from the ground up? Even if they start with another distribution as a base, how do they know (I realize one person doesn't do all the work) what to do, what order to do it in, how to synchronize what they're doing with what everyone else is doing, etc. How do you know which software to compile and install first? etc.
Also, I'm entirely confused by this: how can everyone (even large teams) get everything working together? Knowing that this works with that and that doesn't work with this unless it's patched but that's what we're going with, etc. I can't understand how these things can be done without an almost unbelievable amount of effort unless a lot more is done by ./configure and make than I know about at this point.And I don't understand how libraries work at all. I mean, I'm going to learn a lot more and I've been reading a lot... but how can all the distributions just download and install 50 updates at a time and not have to restart the computer most of the time!? There are a hundred things happening in the background constantly. How does everything not just fall apart as soon as you update one package, let alone 50 at a time!? I realize this is stuff that you learn by reading, but I've been reading for quite a while now and I do not understand even the basics about why any of this works or how to know what works and what doesn't unless every single little piece of every distribution is gone over with a 50,000-page reference manual that's constantly updated. And all of this can't be as complex and hard to do as it seems, or there couldn't possibly be a hundred distributions that work and are updated constantly. Linux From Scratch is a good example. You have to download all the very specific versions of the software and patch it with special little patches, etc. How the hell can anyone keep track of all of this? Going by what I know about things, it's almost hard to believe that it's even done.
/etc is where your gnu/linux stores it's configuration. Its function is similar to the Windoze registry. As you install, uninstall, and work with various programs, /etc changes. Sometimes, things change that make your system act unexpectedly.
1) open a console
2) su enter root password
3) # mkdir /var/backup
4) # vim /usr/sbin/prep4change replace "vim" with text editor of your choice
5) cut and paste the following short script
[code]....
Next time you are about to install, remove, or change something, just issue prep4change as root. If the unthinkable ( but expected ) should happen, and things stop working correctly, you have your /etc and /boot already backed up. Your backup will be located in /var/backup You can also $ tail /var/backup/notes to see why you made what backup Again, this isn't the most elegant, but it's simple, and it works!
I'm trying to make my first c project (a simple tic tac toe console game), and I am wondering how to make a final product (copy all source code files to a distribution folder upon compilation). Should I use a bash script or should I use a makefile to make the distribution folder? I'm not terrible familiar with either; I have a basic makefile to make an executable, and that's about all I know of make.
And if I do use a bash script, how do I copy over source code files? I tried cp ./*.c and cp ./*.h, but I think the script read it literally as moving a file named ./*.c (and ./*.h), and couldn't find it.
My makefile is pretty much this:
Code:
objectFiles = main.o io.o board.o game.o
ttt : $(objectFiles)
cc -o ttt $(objectFiles)
I have s script that standard users use to back up usb drives to lto4 tapes.it asks for a JobNumber and sends an email upon success.I recently expanded it to use Multiple tapes.my specific Q is if the system reaches the end of the tape it happily mentions in the terminal that one needs to put in a second tape.what i would like to do is send an email that --It needs a second tape.( it presently sends an email upon successful compleation - so you see the only way a person knows that they need a second tape is if they
1-- know that the drive they are backing up is < 800GB (lto4)
2-- they do not get a completion emails and the think to walk to the basement and see the request for a second tape.
I wish for an email that would tap them on the shoulder that : " you need to put in a second tape "so -- if i know the exact syntax that shows in the terminal - which is:Prepare volume #2 for `/dev/st0' and hit return:then can i test for that somehow?
I would like to install a program (R for statistical computing). I am using Slackware. On the download page of R (The Comprehensive R Archive Network) there are options to download the code for Debian, Redhat, Suse, and Ubuntu. Which one should I download in my case (using Slackware)? Is there any of them which I should not download?

View 1 Replies View RelatedI'm syncing a server over the internet with rsync, but it only works for a few hours before the backup fails with a "No route to host". I can restart the job and it'll will pick up where it left off, but is there an automated way to do this, or protect against a connection failure? I have about 170GB to copy over initially, but I can only get through about 4-5GB before the connection drops--manually restarting the sync everytime it drops will make the initial backup take days...

View 3 Replies View RelatedWhat exactly allows me to create a custom tailored *.img file to backup the contents of a partition?
This is my problem: My wife wants me to backup some Windows NTFS partitions on her working computer so she can use them on a different computer.
This is my solution attempt:Boot the Gentoo based System Rescue CD. dd the contents of the data partitions into *.img files on an external usb drive. dd the contents of the *.img files onto the new computer.
So far that worked, but there's one annoying problem: one partition on the work computer is 50GB big, but contains only 8GB of data. It would be really nice if I could just dd out those 8GB of "real data" instead of having a 50GB *.img file that is mostly empty. Likewise, it would be cool if there's an easy way to match the contents of the *.img file to the size of the new partition. The new data partition is 100GB big so it would be cool if my backup were automatically scaled to that size so I don't have an 8GB partition and an additional 92GB partition.
wanted to knowIs there a command the root user can type in the command line to list & know all soft and hard links there are in a distro that is installed ?

For absolutely no reason, I reinstalled my Ubuntu. Its not a wubi installation; but a full installation. It didnt cause any problem like old xp days. I just reinstalled because I tried too many themes on that and the system appeared jammed. I could fix it; but I thought a plain reinstallation would be much less difficultNow the problem is, after reinstallation, I have to install all software such as VLC, GIMP, and plugins for mp3 and video codecs. I did know that I would have to download them again. And I will download them shortly. But I want to know is there any way I can preserve the installer of those applications and plugins to use after a fresh reinstallation or upgrade to latest version (say 10.10 for example)?
Also, I want to back up all the system updates through update manager so that I am not asked to update (by downloading 200+ MBs) after fresh reinstallation.Please note that my internet connection is very slow and its bandwidth is limited to 3GB per month. I can buy more space but you know its costly here. That why I want a way to back up all the software, plugins and application installers for further use. I have DVD writer on my machine so if I have to write a disk Im capable.
Every time I install ubuntu I have to reinstall all the software from the software center and so. Now I already installed all software I need for this moment. Is there a way to take source files of those (installed) packages and save them some where else in order to reinstall them if i needed next time without need to INTERNET connection ???
Another question I wanna know about: How can I take a backup of my system as whole in order to get back to it if some problem happened. I used to use Acronis True Image and its alternatives to make a disk image. Is there is some thing similar in linux ?? is there better options ??
I have Ubuntu 9.10 on my system and i have a lot of apps on it.is there a way that in case of a full re-installation or hard disk replacement i could have all my softwares and settings installed on the new Ubuntu installation.

What does "distribution" mean? My Acer computer, on which I have linux linpus lite, comes with very little documentation and while I have a physics BA and have had exposure to technology, my knowledge of linux is just about zip. Is there a good place to start? As you can see, this question about the word "distribution" is a razor thin top of an enormous iceberg of ignorance.
View 3 Replies View RelatedI need a 64-bit Linux distribution to beta test TeraChem, a GPU-based quantum chemistry package. I have never personally used Linux, however, and I don't know anything about the available distributions. I was wondering if I could get some recommendations.
My system specifications:
CPU: Xeon W3520
GPU: NVIDIA GTX 275
Motherboard: GIGABYTE EX-58 UD5
Current OS: Windows 7 64-bit
I would not use Linux as my sole OS but would want to dual-partition (I think that is the term?). However, I think I would end up using the distribution for more than just running TeraChem. I may even become a convert!
What am I looking for in a distribution? Ease of use, efficiency, 64-bit. What do I know how to do? I can build computers, code in C++, comfortably use a command line.
I would like to make my own Linux distribution.Where do I find a Linux distribution that has just the OS, a browser and basic drivers for ethernet, video, etc.I can then build it up myself through the repo.
