Fedora :: Create An ISO Image Out Of A Directory From Command Line?
Feb 7, 2010
I am implementing a strategy to organize my data among the several machines I work with and thought that getting some ISO images out of it could be a good idea because that way data would be 'read only' thus allowing for easier synchronization.
At first I thought of using the "dd" command to create the ISO out of a directory, but it fails code...
So, I have two questions:
Is the ISO 'format' capable of storing complex directory structures with long filenames (pretty much as any Linux filesystem does), or are there some inherent limitations?
Supposing the ISO format is not constrained, which command would allow me to create an ISO file out of a directory?
I am currently interning at a place and my job is to essentially learn UNIX. My supervisor gives me problems here and there to help guide me with my learning but for the most part I'm doing this all by self-teaching myself. Needless to say I have run into a few obstacles...for instance-Create a *one* line command that, using tar, will collect the full /usr/local directory (you need to run this as root again) and copy the whole /usr/local structure under /optFor example /usr/local/bin/hello will become /opt/local/bin/hello, etc. I want this as follows:1. /usr/local is collected by tar, but the output of this tar command is its stdout.. what you get from the previous stdout, you compress with gzip and send it to stdout again 3. get this output and decompress with gzip.. get this output and pipe to tar in a way that will extract the tree under /opt.If anyone knows how I could go about doing this, please let me know, or at the very least point me in the right direction. What I've got so far (which could be completely wrong) is:tar cvf - usr/local/ | gzip -c - | gunzip -c - | tar xvf -in theory I feel like this should work (except for extracting the tree under /opt...i'm kinda stuck there)
problem during fedora x8664 installation. how to give the command for directory path and image located drive. the procedure to install fedora for the first time.
Need explanation from a FTP guide's reference of FTP's GLOB command. mget and mput are not meant to transfer entire directory subtrees of files. That can be done by transferring a tar(1) archive of the subtree (in binary mode). Then FTP does not transfer, even with mput, a directory of files to remote server? Does this quote suggest I can tar my files, upload them, then untar them on the remote server?
Well, I am facing problem when doing lab questions.
I must use DLXLinux bundled in Bochs (bochs.sourceforge.net).
I am required to use the /usr/local directory.
In /usr directory, there is no directory named 'local' but there is one thing called 'local@'. So, when I try to use mkdir command to create 'local' directory in /usr , there are error "cannot make directory.....".
How do I save it as a jpg somewhere on my puter using a script? I can wget, but it gets saved as a .evif, which is totally useless. I can right-click on the image in a browser and use the context menu to save it as a jpg, but I want this process automated. How can I DL this image and save it as a jpg? GIMP's CL options don't include the capacity to save/convert this image, though it's possible from teh GUI. ImageMagick won't read this dynamic URL. What do I do?
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
I admit PV is new to me, compared to simple HVM, so I have a number of questions:
1. Why the command not found error?
2. Should I be booting from the Xen option or regular boot option at the start up screen when creating the xen image? I've tried both and get the same error message.
3. I have Debian 8 (Jessie) installed on my system and I wasn't sure whether I should therefore make this the guest OS in my Xen PV. In asking this question I'm thinking in terms of HVMs - but I assume my Xen PV needs a guest OS of some kind? Or is my host Debian 8 already acting as a guest OS in Xen PV? I'm confused
4. If I do need to install a guest OS, is it better to go for an earlier version of debian - so as not to be so resource hungry?
I'm nervous about screwing up my host debian installation, so when I got the error message, did some research but found nothing meaningful. I don't want to end up having to reinstall my Debian 8 (base OS) ... again!
I do computer forensics here in Afghanistan and I am trying to keep a clean image of a dual bootable hard drive. Here is what I try to do...
1. Boot into UbuntuLiveCD 2. I run "sudo dd if=/dev/zero of=/dev/sda conv=sync,notrunc bs=64K" to wipe the drive with all zeros. 3. I then install Windows by creating a new partician about 50GB. 4. I then install Linux by creating a partician in ext4 mounting it at '/' in addition I create a swap partician. 5. Next configure everything just the way I want it. I install all the drivers and software I need for my windows partician and build out the remaining part of the disc as a "data drive." 6. Then I use "dd" again to try to image my "clean slate" of a system. Remember I am dual booting. I dd the /dev/sda and gzip it. 7. When I go to restore it, I boot from the live CD again and unzip ig and "dd" it back onto /dev/sda. 8. I run fdisk -l and I get:/dev/sda1 * 1 6375 5120000000 7 HPFS/NTFS/dev/sda2 6376 11724 42965842+ 83 Linux/dev/sda3 11725 12453 ...... 82 Linux swap / Solaris.This means to me that it can "understand the file system" 9. But then when I take out the Live boot CD and try to get my "clean slate" machine back, the system goes into Grub Rescue mode with a grub command line "grub rescue>" 10. I tried using the tutorial on Grub2, but... a. It would not understand the command "linux" b. When I try to do insmod, it says it doesn't recognize the file system.
in the command line there's a button (tab) for autocompleting commands and I'm pretty sure linux has a button that prints the last directory I used/typed whatever?
I am struggling to learn the command line, and am stuck to the following In my directory ~/Music , I have many music archives , total about 0,8 Gbyte . Yet , changing to this directory ) and giving ls -dlh , I get
ioannis@ioannis-laptop:~/Music$ ls -ldh drwxr-xr-x 4 ioannis ioannis 4.0K 2011-03-04 14:55
So, only 4 k size and no info about the number of the files in the dir

i have a server running on centos5, i have run vsftp and samba, and i need create a user through command line and set your default directory, i can do this through graphic interface, but i need do throug line command.
I am looking for a way to (via bash script) set a custom directory icon for a number of directories. All of these directories contain a "cover.jpg" image. I can accomplish this manually by right clicking the directory > select "Properties > click the directory icon button > select the "cover.jpg" image. I am just looking for the way to do this in the terminal to save time, as the music collection is quite large.
I have just installed the 32bit and 64bit versions of CentOS 5.5 and was wondering how I can add these machines to Active Directory for authentication. I've done this in the past with CentOS 5.4 using the GUI and everything worked just fine but now need to do everything from the command line.
I use putty to get to my RHEL 5.3 workstation from my Windows laptop.
Typically, if I want a new terminal on my windows 7 workstation from another terminal or mc, I have to type start and I will see a new terminal window running the default shell.
QUESTION : What is the equivalent command in RHEL 5.3 (and or solaris) to create a new terminal window from the command line ? I will be entering this command from the shell prompt or mc's command line.
In Windows, if I want to start another terminal and in that terminal, I want to run a program, I can do "start program.exe arg1 arg2". this will create a new terminal window and runs program.exe in that terminal window. I don't have to create a terminal and then in a separate step run the program. How can I do this in Linux ?
I use a few command line programs quite often such as nano and mpc. I'd like to create a shortcut icon to open them rather than opening a terminal and then typing in the program name to open it. For example, how could i open konsole with nano opened in one step?
I can do:mkdir messages and then: touch messages/hello.txt Is there a command that will do both - create the directory if it doesn't exist, and then the empty file? Something like: touch -p messages/hello.txt
