General :: Comparing Multiple Of Files ?

Mar 20, 2010

I am fairly new to Linux and was needing some help on a comparing more than 2 files. I am try to come up with something that would compare at least 10+ different files to a master file and give me an output of what is missing.

Example would be: a.txt, b.txt, c.txt, d.txt compare each of them to the master.txt file, than output the missing text for each file into new file.

I came across comm and diff commands, am I looking in the right place or is there a much easier way of doing this?

Ubuntu :: Comparing Multiple Files In Shell Script?

Jun 13, 2010

I've got an interesting challenge for the shell scripting wizards here. I've got a mySQL dump of three files for my amarok database with the intention of copying some files to my media server (cover art) so that I can keep the server the server and not rely on my local machine.

Step 1: Identify any cover art files on my local machine.

I did this with:

Code:
mysql -u amarok -p amarok -e "SELECT * FROM images WHERE path like '%.kde%'" > cover_art.txt
Output looks like this:

[Code]....

What I have here now is the ENTIRE album list in my collection -- and something to compare the IDs in Step 1 against. I'm going to stop here and will update the thread as I get past this stumbling block. "ID" in cover_art.txt = "image" in albums.txt... straightforward enough, right?

So the question is this: how do I create a simple shell script that will loop through the IDs in cover_art.txt (i.e. characters 0 -> 4 -- it will always be a 4 digit ID) and then search for that ID in the Albums.txt file.

General :: Comparing Two Files - Display The User Names That Are In The First File And Not The Second

Sep 17, 2009

Im trying to compare two files and I only want to display the user names that are in the first file and not the second.

So I have one file named final.txt (which contains every user name and only the user names in a list no other information)

Then I have another file Over1.txt (which only contains certain users that have different permissions This file is also setup differently with the user name and some information about the user after the user name.

I need a way to compare final.txt to over1.txt so that I will only display the names that are in final.txt but not Over1.txt

Ive tried using diff and comm but just cant seem to get it two work correctly. Im not sure if im missing a option or what.

Programming :: Comparing Two Files ?

May 7, 2011

I have two files

Code:

we have to consider here $5 , $6 , $7 for our search

file2.txt

Code:

Here we should take only $2 for comparison. As you can most of the $2 field records has value and some do not have value.

Question:I want to take the fields $5 , $6 , $7 from file 1 and compare it with $2 field from file 2. and the rsult should be like this:

Code:

The final output will look like this

Actual file1.txt (before running the code)

Code:

FIle1.txt after running the above said condition

Code:

So the field $5 , $6 , $7 should get replaced from the matched valued of $1(file1)

I have 2 very long files which are quite similar:

I need this output:

Code:

explanation:

If the fields 3 (serie) and 4 (modello) are identical, the lines of the 2 files should be "added":

Code:

If the fields 3 (serie) and 4 (modello) are different, just print the line of both files:

Fedora 15 Alpha

3494 user 20 0 1028m 50m 21m S 12.8 2.5 1:43.32 evolution

I just wondering what is the difference between RES, SHR, and VIRT.

1) The VIRT always seems to be higher. Is this using the paging file system. (virtual memory on the harddisk, the swap memory)

2) Is the RES memory the actual physical RAM memory?

3) Is shared memory sharing memory with other processes?

4) Just a final question. As I am running on a HP Mini 210, memory and CPU is a resource I don't have a abundence of. So if was to compare for example 2 difference browsers i.e. firefox and midora. What should I brench mark between to 2 to find what one uses less resources?
