General :: Replace The Two Parameters "source" And "destination" With?
Sep 22, 2010
I 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.

why do we have to define both Source/Destination AND Direction when building firewall.Isn't direction= source->destination? what would happen if source and destination were swapped?

To 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?

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.

Which of these (if any) are correct?
cp -r /var/www/vhosts/niftyfiftyparty.com/httpdocs/sites/all/modules/*.* /var/www/vhosts/keylargodivecenter.com/httpdocs/sites/all/modules/*
in /var/www/vhosts/niftyfiftyparty.com/httpdocs/sites/all/modules/
cp -r *.* /var/www/vhosts/keylargodivecenter.com/httpdocs/sites/all/modules/*
in /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?

When I use the cp or mv command to copy/move files is there a way for me to have the destination file assume the same name of the source file, however add an additional suffix.
For example
Code:
Now what if I wanted this...
Code:
Do I have to type the destination file out manually everytime? or is there a quick way for the cp or mv command to assume the source file name and add the .bak

Let us assume I have a zip file called patch.zip, when I run unzip -l patch.zip I get the following output.
bin/a
bin/b
lib/c
To this zip file I want to add a new file, "Readme.txt" located at /path/to/Readme.txt in such a way that, when I re-run unzip -l patch.zip again I get something like this
bin/a
bin/b
lib/c
doc/Readme.txt

We used to send files in the form of .jpg, .tif, and/or .pdf. Normally the file name will be in the form of 08072011IE01CTYHUB.PDF (DDMMYYYY - is the date, IE - publication, 01 - page number, CTY - edition name and HUB - destination in three characters). These files will be stored in a common folder (say SOURCE). I need a script to move these files to destination by reading the destination from the file name through FTP. At destination these files should be moved to a folder meant for CTY. Please note before the file is sent through FTP it should be compressed (zipped) At SOURCE folder the files will be as:
08072011IE01CTYHUB.pdf
08072011IE01CTYSMG.pdf
08072011IEdavanamCTYHUB.pdf
08072011IEversaVANSMG.tif
etc. where first 8 characters are date in the form of DDMMYYYY, next 2 characters are publication, last 3 characters are destination, previous 3 characters are edition and left over in the middle are page number in the form of NN or name. Presently I am zipping these files and send it through FTP to the destination. At destination my counterpart takes the file, stores in appropriate location (like folder name CTY) for use. To automate the above process, I want a script.

I'm trying to install Slackware package into some specific locations, like for example, I want to put Linux base package into at / and put applications on /usr/local. However when I'm installing using "setup" program, I cannot find a part that let me to choose the installation destination.
At "setup install" option, it gives six different installation method like full, newbie, menu, expert, custom, and tag path. But none of them (I cannot find it) gives an option where to put the installation package to.

Suppose I have a tree structure like this:
/home/mahmood/sim/a/b/file1.cpp
/home/mahmood/sim/a/b/file2.h
/home/mahmood/sim/a/c/file3.txt
/home/mahmood/sim/d/file4.txt
How can I copy all of them to /home/mahmood/sim. So that when I run "ls" in /home/mahmood/sim, I see all files:
file1.cpp
file2.h
file3.txt
file4.txt
Can 'cp' search for all file and copy them in another folder?

I have recently purchased an external hard drive in order to backup my home partition. In my PC I have a "1.5T" drive with several partitions on it, containing OSes and the home partition. The home partition is 1.3T according to df, the external drive contains one partition that spans the entire disk,df reports it as 1.4T in size. Both partitions are ext3. When I use rsync to copy files from the home partition to the external partition, the external disk becomes full, despite the destination - supposedly - being larger than the source. I don't understand why copying files from one partition to a slightly bigger partition should need more space than on the source partition. Does anyone know what is happening ?
Details : I created the partition on the external drive with gparted; gparted reported it the already have several gigabytes in used space immediately after the partitions creation - I thought at the time that this must be normal. The home partition contains many files of all sorts, including lots of big audio and video files. If you are wondering, for all my important files this external disk is only secondary backup, as they are also backed up to the "internet".
These are the mount points :
/mnt/tmp/ : home partition, /dev/sdb6
/mnt/external/ : external partition, /dev/sdc1
I used rsync to copy the files, I know there are more efficient ways to do this, but I wanted to use the same command that I will subsequently run to sync the backup.
rsync -av --progress --stats --recursive --perms --links --delete /mnt/tmp/ /mnt/external/
Next I tried adding the --sparse switch, as I was wondering if the problem may come form sparse files. I don't know however if rsync would go back and shrink the sparse file by just adding the switch and executing the command. I also added --one-file-system, for good measure. Here is what I ran next :
rsync -av --progress --stats --sparse --one-file-system --recursive --perms --links --delete /mnt/tmp/ /mnt/external/
I tried an fsck on the home partition :
fsck -f /dev/sdb6
This is the output from the last rsync :
rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Broken pipe (32)
rsync: write failed on "abcd.avi": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(302) [receiver=3.0.6]
[code]....
Looking at the destination after a partial copy seems to indicate that the problem is not symbolic links being "expanded". I have not checked the source filesystem for sparse files, nor the destination to see if these files could be larger there, as this does not seem trivial.
Here is some additional info :
$ df /mnt/tmp/
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb6 1415342836 1414173740 369096 100% /mnt/tmp

We have an rsync cron job set up to mirror all the files in a "..dashtdocsdocs" folder to the same folder on another server. It copies all the files over correctly and deletes any files in the "docs" directory that aren't in the sending directory, but it also deletes any files we put in the target directory's parent folder (..dashtdocs or other subfolders like ..dashtdocsimages) even though they've been excluded in the .rsync-filter file.
Here's our current rsync .sh:
/usr/local/bin/rsync --stats -qPzrtpl --delete --password-file=/var/run/.appprodrsync --log-file=/export/home
/webuser/logs/rsync-extranet-log -FF /export/home/ appprodrsync@appprod::dprweb_extranet/ > /export/home/webuser/logs/rsync-extranet-output 2>&1
[code]....
So for example server A has ..dashtdocsdocs and ..dashtdocsimages. Server B has ..dashtdocsdocs but if I manually copy the images folder over to ..dashtdocsimages, the images folder gets deleted from the target directory every time rsync runs.
A: ..dashtdocsdocs
..dashtdocsimages
B: ..dashtdocsdocs
..dashtdocsimages (<-- gets deleted everytime rsync runs)
I'd like to keep just the docs directory synched and update other folders manually, but they keep getting deleted. It looks to me like it's running a delete-excluded option, but that option wasn't used.

I cannot access/ping my Debian server. I know the IP is right (ifconfig, route and ip addr) all gave me 10.0.2.25 (route gave me 10.0.2.0).I cannot ping it from any computer in my netwerk, even when I try to ping it from my Debian itself, it gives me Destination Host Unreachable !(Wierdly, I can ping 10.0.2.2 tho).I am using virtualbox when the netwerk options 'NAT' turned on. When I look at my /etc/network/interfaces/ the last line looks like:iface eth0 inet dhcpShouldn't their be some other stuff listed?

Today i am trying to learn how to use sed. I set up a testing folder with the following files:
AAb.lol
AAc.lol
AAx.lol
test.sh
My goal is to create a script (test.sh) which renames all the files to their original name without AA. I want to end up with this:
b.lol
c.lol
x.lol
test.sh
sed seemed to be the perfect tool so i went ahead and created a script which i think should clear the job.
[Code].........
mv: missing destination file operand after `$i' From that 2nd line i can tell that $NewName is just empty. I also read something about sed needing the -e option for scripting purposes but i just don't understand it.

This is a WHAT I WANTAND NEED IN A LINUX DISTRO, not a your preference request. Fairly literate with Windows XP, but would like to find a Linux Distro with specific features. Computer used for music (over 14k mp3, ogg Vorbis, etc files) and burning musical learning tracks (I'm a barbershopper) as well as simple surfing and email. Not a gamer. Older Computer: PC with 1.4 GHz Athlon partitioned 320 Gig HD (Windows XP and a Linux Distro??) Only have CD-ROM, cannot download & burn iso DVD's or upload from them. (Can do CD's) Do have a 1 TG Verbatum external HD and a newer computer with a dvd recorder/player
So:
1) MUSTt have a distro that doesn't require a DVD for installation.
2)MUST be able to "update" rather than re-install subsequent releases ( which require backing up files, etc)
3) Like the description of Linux Mint Helena, but it requires installation from a DVD and a re-install..
4) Free distro since I'm learning and trying out different OS's and really resent the increasing cost of Windows OS's as well as the complexity and problems with Windows. I've found that UBUNTU 9.10 doesn't like me. I am very comfortable with LINUX MINT HELENA.
