Ubuntu :: Create Two Lists Of File Names Irrespective Of Directories And Compare?
Aug 13, 2010
I have an internal hard drive and an external hard drive, both with about 350 GB of data. The data came from the same source, but over the last couple of years, different people have moved files around to different directories, and some files have been deleted. Now I want to merge all the files onto the internal hard drive. I estimate that 80% of the files on the external hard drive are the same, so I don't want to copy 290+ GB of data over when I already have it.
Therefore, I need a way to find just the files on the external hard drive that don't already exist on the internal one. In other words, I need to create two lists of file names irrespective of directories and compare them, selecting only the file names that exist in one list OR the other. I've Googled for solutions but can't find anything suitable. There are ways to create text files of the file names and compare them with diff, but they have to be in the same order, and since these files are in vastly different directories, that won't work.

I need to get names of all installed packages in 2 machines and save them in 2 text files, then I want to compare these 2 files to know the differences between 2 files and from that I could know the differences between 2 machines. Is it possible to do that and what program I could use?

I'm not sure if this is possible or even where to start. I assume that this can be done with an sh script using tar or similar.I have several very large zip files that contain images for all of the products in my online store. Each image is named after its 13 digit SKU (for example, 9987788000012.jpg). In order to import products into my store, all images are placed into a media directory. Unfortunately, there are over 100,000 images.
So I would like to break the images into sub-folders based on file name. For example, when I extract store_images.zip (or tar or whatever), my extract script would create directories (if they don't already exist) based on the first three digits of each image name, placing each image into the appropriate bottom level directory. For example, "9987788000012.jpg" would be placed in the following directory "media/9/9/8", with media as the root and "8" as the directory that holds any images that start with "998". Perhaps two sub-folders would be less cumbersome.Assuming this requires a script, particularly since it involves scanning image names, creating folders, and saving images to specific directories, which language would serve my needs best? PHP? Has anyone had to do something similar?

I have a bunch of .7z files in a directory, and I need to put each one of them into a separate directory, named after the file (without extention). The command line I use:
Code:
find . -type f | mkdir `sed -e "s:..(.*)...:1:"` ; ls | grep .7z | cp * `sed -e "s:(.*)...:./1/:"`
Copying fails though:
[Code]....
PS. I don't want to use scripts, I want to do it using simple commands and piping.

The uuname command available in solaris lists the names of systems known to uucp. Since uucp is also available in linux, is there any command which lists the names of systems known to uucp in linux? I 'm using fedora9 linux machine.

quickest way to create directories from a .txt or .csv file. A single command would be great but I can use a script as well.
The windows equivalent would be:
FOR /F %n IN (newfolders.txt) DO MKDIR %n

Firstly i'd like to introduce myself before I ask my question, i am currently studying a "Network Operating System 2" course, and in the syllabus the professor decided to use Ubuntu Linux for us. This is a first for me and I am truly greatly interested in the OS. It seems like a solid system once you get to know the deep foundations of it. The professor has already given us an assignment, but I feel its not fair as its just a bit too much from out of what he taught us .. He did not teach us what he is asking for. He asked us to create to a text file which lists the Sales from two Salespersons, and each one will have an amount for each month .. So 12 entries for each salesperson.
Using that text file, we should write a bash script which would read the values from the above text file, and produce a "Monthly Sales" text file, which shows the total sales of each month (combined from both the salespersons). I would like to ask for some guidance, some help on how to start. It's just that he didn't teach us any commands about this matter.

I have to write a script that accepts two directory names (JIIT, JUIT) as positional parameters and checks which files are identical in both directories and files having same contents are also considered as identical in same directory. I tried using diff:
#both directories contain three files...file1, file2, file3
echo "Enter the directories:"
read d1
read d2
cd $d1
if diff file1.sh file2.sh > /dev/null
then echo same 1,2
else echo different
fi
if diff file1.sh file3.sh > /dev/null
then echo same 1,3
else echo different
fi
if diff file2.sh file3.sh > /dev/null
then echo same 3,2
else echo different
fi
cd ../
cd $d2
.....
I used the same code in the other directory for the three files. This is not running. I also want to know what to do when I need to compare files from different directories. i.e., JIIT, JUIT..

I want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?

How do you tell a shell script to search for the directory within another directory (in this case /lib/modules) whose characters in its name (in this case numbers) are highest? I want to be able to tell mkinitramfs in a script to be able to see the highest possible kernel version in the /lib/modules directory.

I need to replace ":" from multiple files names, since I am going to copy those files from a linux partition, which admit the ":" to a FAT32 partition, which does not.
Example:
original name: eg06_ana_21-05-06_09:21:03.JPG
wished name: eg06_ana_21-05-06_09-21-03.JPG
I have googled a lot but I have not been able to adapt the examples given by people to my aim.
It seems that rename command is what I should use, but I have no idea to build the correct pearl expression.

I am playing around with RH for the first time. I have two applications which insist on using names for network ranges - so they need /etc/networks. I created one on the RH box as suggested via google but the apps still cant see the names (basically they are not reading /etc/networks). What is the correct process to create network names on RH? Basically the equivalent of solaris /etc/networks?

Is there any utility that can provide a list of all files, and both the file size and md5 hash value. Preferably also including other hash values.I've got 1.5 TB of files to go through, and delete duplicates..Neither fdupes or fslint are up to the task --- both claim files to be duplicates, when they definately are not. (Movies, and OOo documents are not identical, even if one is the script for the other, which in this case is not the case. Both fdupes and fslint claimed that those two files were identical. (And yes, I did look at them.

I have not ran into this before. I did a new install of 10,04 and was adding programs. Then software center and Synaptic stopped working. error message said it was most likely due to unmet dependencies. I googled fixs which most all ran some sort of "apt-get" command. I can't run those because as soon as it gets to "Reading package lists", I get this error.Read error - read (5: Input/output error)The package lists or status file could not be parsed or opened

have been working how to do this for a while finally getting around to asking....
as a long time windows user I have used a trick of creating directories that will always be the first ones displayed by using an _foldername model, for ex:
_temp
A dir
B dir
temp
assuming the four above are directories that is how they are sorted by default in windows and I commonly use this technique for special folders.
for my virtual machines folder in windows looks like this:
_base
LX-Ubuntu9.1
LX-Ubuntu11.4
XP-TestVM
...
where I put base virtual machines in _base and it makes it easy to separate them for all the other folders which are virual machines....SO....
in Ubuntu, I cant figure out a character or way to ensure this type of behavior, for example if I create a _base folder it shows up after a dirs and around the bs etc...
any know a way to create a dir with a special char that will ensure it stays on top?

I am trying to write a script which compares a log file with reference file. The log file has a table, the LHS of the table are constants strings and RHS of table values changes if there are any changes in configuration.code...
Here I am looking for a script which compares test.log file ( whose RHS data-types are known prior whether it is digit or string) with test.Ref which is reference file for test.log file. It will be really helpful for me if any of you give some idea about writing this script.

I got a file with a list of subnets like this:
10.50
10.51
10.62
10.121
then I cnf=`ifconfig` thus giving me the config of the NICs.after that I want to compare the $cnf to see if the value of it is listed in the file and if it is do things.There might also be something better to use then the 'ifconfig'but it worked so I just stuck to it First I just had one subnet but now it's starting to grow and I wanna make a list instead of having them all listed in the if-statement.
