General :: Detect Duplicate Files Using Md5sum ?

Feb 21, 2011

What i am trying is to check the file duplication in a folder and remove a file if it is a duplicate of another file ie the contents are duplicate; but names may be same.

Basically i am using md5sum to calculate the md5sum values of each file and redirecting to a file. And i am thinking of comparing the md5sum values.But i am finding it hard to decide how to complete the code after redirecting the output of calculation of md5sum to a file.

General :: LVM And Plug The External USB HDD - OS Will Detect A Duplicate LVM Configuration, With The Same Name And UUID

Mar 11, 2011

Using Linux, I have several backup levels. One of them is a periodical sector by sector copy (using dd) of my laptop harddisk to an external USB disk. Yes, I have other backups too, like remote rsync. This approach (the disk dd) is OK when cloning a HDD with no LVM volumes, since I can plug the external disk anytime and mount the partitions simply mounting /dev/sdb* instead of /dev/sda*. Trivial and handy.

Today I moved ALL my harddisk (including the /boot) to LVM. Everything works fine. I will stress it for a couple of days, and then I will do a sector by sector copy to my external harddisk. Now I have a problem, I guess.

If in the future I plug the external USB HDD to recover any file, the OS will detect a duplicate LVM configuration, with the same name and the same UUID. Even doing a vgrename (which LVM would be renamed, the internal HDD or the external HDD?), the cloned UUID will not change. Is there any command to change name and UUID? Ideally I would clone the HDD and then change the LVM group name and its UUID, but I don't know how to do it. Another related issue would be... In the past I have booted my laptop using the external disk, using the BIOS boot menu and changing GRUB entries manually to boot from /dev/sdb instead of /dev/sda. But now my current GRUB configuration boots directly from a LVM logical volume, something like: set root='(LVM-root)' in my grub.cfg. So... What is going to happen with duplicated volumes?

General :: Package Versioning And Difference Of MD5Sum On Files?

Jun 20, 2011

I noticed something a little odd I'm hoping someone can enlighten me on. I noticed in a couple of cases that a package has the proper version, but differs in two regards.

1. The package ends up with a .el4 on the end of the version for Red Hat 4.

2. The actual MD5Sum of the files the package provides differ.

An example below:

Code:

[root@RH4ES32-MCE bin]# for i in `rpm -ql GConf2`;do md5sum $i;done;
md5sum: /etc/gconf/2: Is a directory
9f90335546f7c57ae6fb552cc2b919c5 /etc/gconf/2/path
md5sum: /etc/gconf/gconf.xml.defaults: Is a directory

[code].....

So my package changed slightly to now show .el4 versus just 2-2.8.1-1 I've indicated in the first output above that the first couple of lines differ. I stopped my comparison at that point as they truly are different.

General :: Back Up Scrip - Find / Cp / Md5sum / Rm - Move All Files And Directories

Oct 22, 2010

I want to move all files and directories that are 1 month old out to back up into a separate folder. There will be a lot of files and I want to make sure it copies properly. The problem I'm having is integrating a MD5SUM into it to check integrity. MD5SUM is not recursive, so I figured it would work in a loop when it copies each individual file, I'll do a md5sum on each file and delete that md5 once its verified it copied ok.

[Code]...

I also need some sort of error handling to output all md5's that didnt pass the hash check.

General :: Find Duplicate Files Using Bash Script ?

Jun 8, 2010

What kind of method to find the duplicates files on linux,

1.how to find just using the file name, sometimes i figure out people often to copy their files to another directory and i want to find out if there any same file name in the linux box.

2. what about if i want to find the duplicate files based on contents of the file, example is in picture file if users store picture files from digital camera first they just save the file name in default but when they want to give that picture to others they will rename it, i've been used method md5 for this situation in python script but it takes long time

I'm asking this question just to know to use bash script a lot in work and i want to test out fdupes at home, is fdupes use similar md5 scan to find duplicate files?

Ubuntu :: Md5sum - Fast Way To Verify Huge Files

Oct 29, 2010

I'm looking for a fast way to verify a copy of a folder with 150Gigs of data, in 33 files. Some of the files are a few kb, while a few are 20-30Gigs. I've done a file count, which is quick, but doesn't verify that all the files are intact. I tried running md5sum on them, which works, but will probably take as long as copying the files in the first place. Diff works too, but is slow too.

Programming :: Compare Two Md5sum Outputs To See If The Files Match?

Nov 5, 2010

I would like to compare two md5sum outputs to see if the files match. in my script I have

Code:

ORG_FILE="/path/to/org/file.zip"
NEW_FILE="path/to/new/file.zip"
MD5_ORIG=$(md5sum -b "$ORG_FILE")

[code]....

How do I get just the MD5 hash and not the */.... stuff so I can compare them. i tried Code: JUST_HASH=${$MD5_ORIG:0:32} but All I get is

dir_mon_notify.sh: line 79: ${$MD5_ORIG:0:32}: bad substitution

Programming :: Finding Copies Of Files Based On MD5SUM?

Jul 13, 2010

I have a directory with some data files in it. I did an md5sum find, and built an index of all the files contained:

Code:
find ./* -type f -print0 | xargs --null md5sum > MD5SUM

Now, based on my new index, I want to find the copies of these files as they appear in a new directory, where they have been renamed and reorganized.

Ubuntu Installation :: Md5sum: WARNING: 1 Of 62 Listed Files Couldn't Be Read

Oct 17, 2010

In order to upgrade a machine that can not successfully upgrade to 10.4 I downloaded and burned the 10.04.1 iso image off the ubuntu alternate download site. In my first attempt I unsuccessfully burned the image with it failing at the very end. I did perform an md5sum on it and received the precise output I got from my second burn attenpt which DID complete successfully. Here is the output:

[code]...

I did research this last night and it seems the common wisdom was to reburn the iso (which I did twice) or copy down the iso again. This I also did and it came down precisely, bit for bit, the same as the first one. Here are the two cksums

[code]...

Is there something wrong with this image on the website or is the error about 1 file being unreadable (could that also mean missing?) be erroneous?

Software :: Duplicate Files And A Basedirectory ?

Dec 28, 2010

I have two directories, I want to know which files in the second directory also appear in the first and delete the duplicate in the second directory. Filenames might be different (so that rules out diff).

My problem is that various programs (such as fdupes and freedup) are very capable of finding duplicate files but randomly delete (or link) files from the first or the second directory.

Here an example with fdupes:

Code:

As you can see, the file in the third pair is removed from dir1 instead of from dir2. My aim is to have only files deleted from the dir1. I know that fdupes can't do this, as I emailed with the author.

Ubuntu :: Bash Script - Not Duplicate Files?

Sep 1, 2010

I am working through a collection of many thousand photographs in many collections, spanning decades. One of the folders is a "Selected_images" folder which should only contain copies of images from the collections.

How can I check that the files in "Selected_images" are all indeed copies and have an identical counterpart somewhere in the collections hierarchy, not necessarily with the same name?

At present I am scanning the output of fdupes -r collection, which is tedious (although, in fact, no photographs should ever be duplicated except in "Selected_images").

MY folders are quite alike so I would like to stop the NON-duplicated files for that I want to be able to do some checks not only for the filename but alsofor the filesize (might be the case that two files have same name but not size).

The ideal would be to suggest me such a program with gui but if not I will try run any script code that is available outhere.

Programming :: Script To Remove Duplicate Jpg Files

May 25, 2010

Thanks y'all for the great script and explanation. This helped a lot in my own project. I thought I'd share the efforts.The project is this: I've got lots of duplicate JPGs from all the family members who've named the same photo with different names. Since md5sum generates a "fingerprint" based on the file contents, not the name, I want to use the md5sum of each jpg to uniquely name each photo and also remove exact duplicates.

It has the following flaws:
0) it doesn't handle certain non-alphanumerics
1) it keeps both photo-shopped and unaltered photos (different md5s)
2) it (currently) doesn't preserve descriptive filenames.

(For me, removal of duplicates is more important than keeping the filenames. I may change that to concatenate the md5 and the filename.)Please note that the commented "rename" command should be used to strip non-aphanumerics from the file names, and the script should be launched with the commented "find" command.
