When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.
View 4 Replies View RelatedTo make a full backup I run a live Knoppix DVD and clone the computer's HDD to an external HDD using the dd command. Is there a possible problem with the source being copied onto bad sectors on the destination disk? If so is there a way to prevent this from happening? A typical dd command I use looks like: dd if=/dev/sda of=/dev/sdb bs=4096 conv=notrunc,noerror. Is this the recommended command for cloning to a disk of equal size?

cp -r /var/www/vhosts/niftyfiftyparty.com/httpdocs/sites/all/modules/*.* /var/www/vhosts/keylargodivecenter.com/httpdocs/sites/all/modules/*

cp -r /var/www/vhosts/niftyfiftyparty.com/httpdocs/sites/all/modules/*.* *
Both the source and destination folders are valid. There are several folders in the niftyfiftyparty modules folder that I need in the other one.
Using iptables is there a way to switch the destination IP to become the new source IP and forward that connection.iptables store the src and dst IP in a variable for a particular connection?

View 3 Replies View RelatedI have six .iso files of CentOS 5.5 (I believe it is a distro of Linux) in a removable External HDD and I want to combine the six files to an only iso. I searched on the Internet and found a script named mkdvdiso.sh and the syntax of that script is: ./mkdvdiso.sh /source /destination/DVD.iso However, I don't know what I can replace the two parameters "source" and "destination" with. I have tried everything I can but it's useless.

I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.

View 3 Replies View RelatedI currently store my backup files onto 2 HDDs that I have in external USB enclosures, one is 1.5TB and the other is 2TB. They both basically mirror each other, but is done by manually copying files onto one and then the other. My goal is to have a Raid level 5 system and I know that level of Raid is a minimum of 3 disks so I'm wondering what my current options are with Raid level 5 in mind.
I can immediately wipe out one of the two drives I currently have with the second requiring some time to offload data from if it is not possible to proceed with Raid unless I have this second disk free. So my situation is this. Is it possible to do something right now with two disks and then convert to Raid level 5 later once I have a third disk without starting from scratch?
I'm using rsync for a backup-sript at the moment and want to keep all files. The files are always unique, so I want to rsync without delete any file on the destination.
I've tried with --no-delete and --max-delete=0 but nothing seens to work. Is there even a possibility to do so?
Before, the "sudo cp -r" command automatically set the permissions to make the directory / files can be accessed by others.
But, after I reinstall Ubuntu 9.10 and apply all the latest updates, "sudo cp -r" command set the files to be accessible by root only.
After I copy the codecs directory to /usr/lib by using the above command, not only I cannot view the files inside, SMPlayer and other player software cannot access the directory.
To fix this, I have to run the chmod command to change the permissions.
Does anyone face this problem? Was it caused by the installation of latest updates?
I am doing a LVM replicate to another server.
Example: server1.foo.com has / , /boot , swap and few LVM partitions. All are in /dev/sda disk of size 80GB. /dev/sda5 is a LVM partition which has only one vg00 and it has 2 LV's (/var and /usr) and a SAN storage connected to this server which has around 500GB of single partition(a LV partition) called /data and its under vg00 .
Now I have build another server called "server2.foo.com" with same RedHat OS version - RHEL 4 and want to import the same LVM setup at destination. Down time or unmounting the filesystem is not a problem (but am trying to reduce the down time as much as possible). Is there any way that I can take a proper snapshot of whole LVM disk and restore with same setup at destination without losing the data and the lvm file system layout?

View 9 Replies View RelatedI'm getting ready to deploy a Ubuntu server in a remote location. I am deathly afraid of something going horribly wrong though, so what I'd like to do is be able to somehow image the system when it's working, and be able to restore that remotely via SSH if things go to hell. My first thoughts were that I could partition the hard drive, and install two separate instances of Ubuntu. One would be the server in it's working state, and the other one would be a separate instance of Ubuntu that I could boot into to restore an image (if that's possible).
1. If I had two separate instances of Ubuntu on two separate partitions, and I was currently booted into one of them, would it be possible to tell the Ubuntu server to reboot and boot into the other instance of Ubuntu on the other partition over SSH? (SSH is the only form of access I will have to the server)
2. Is there a better way to remotely restore a server than what I outlined above?
3. Also, I've used the dd command to make backups before, but it copies an entire hard drive byte for byte. Is there an argument I can tag on, or another command to use altogether that will only copy the bits that are being used?
On Ubuntu Desktop editions, there is a GUI application which allows easily changing to a different server. It can even find out how one is the fastest update server.Is there a corresponding command line tool available to do this? Because I'm using the Server edition without GUI. I hate to manually edit /etc/apt/source.list.
