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)

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.

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.

Programming :: Bash Script - Merge Files Comparing Columns

Apr 13, 2011

I have 2 very long files which are quite similar:

file1.csv:

Code:

file2.csv:

Code:

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:

Code:

Is there a way to do this without reading the (huge) files with a "while read line" loop?

Ubuntu :: Command With The -r Option To Compare A Large Number Of Files And Files In Subdirectories

Jun 16, 2011

I am using the diff command with the -r option, to compare a large number of files and files in subdirectories. My main interest is to find out which files have been changed, and not what the actual changes are, and since a lot of files has been changed, it would be a lot easier to view the file names only. Is there and option for diff that might do this, or does there exist a similar tool/command that could do the job?

Programming :: Command For Find/Replace In Text Files (inc. Files In Sub-folders)?

Oct 11, 2010

I found this command that works great finding and replacing a simple string to another in files located in that folder and all sub-folders.

Code: find . -name '*.php' | xargs perl -pi -e 's/OldText/NewText/g'

The problem I have is that I need to replace a more complex string, like this: Old string: /mnt/stor6-wc2-dfw1/627896/982574/ New string: /mnt/stor8-wc2-dfw1/369587/302589/ There I don't know how to do it... since the / is what separates the old from the new strings, and the strings that I want to replace have / in it. Also, I would like to know how to specify under what folder replace the files, for example, I want that it search/replaces all files under /var/www/mysite/htdocs folder.

Ubuntu :: Command Line To Copy Files From One Location To Another / Retain Source Files Group / User?

Feb 20, 2011

Is there a method at the command line to copy files from one location to another and retain the source files group and user?I'm migrating some MySQL files from one machine to another.I want to back-up the original files in the directory presently. They have owner:group of mysql, some have owner:group root:mysql and so on. To copy them under cli or Nautilus everything changes to root for I execute sudo cp or gksudo nautilus and copy via gui.

Since it is MySQL data I could simply do a dump of the database and restore it on the other machine. But there's about 20 db's and I want to do this via a copy for it will be faster - at least that is what I think.

General :: Comparing Resources Using Top?

Apr 6, 2011

Fedora 15 Alpha

3861 user 20 0 904m 128m 33m S 0.7 6.4 1:11.52 xulrunner-bin
1323 user 20 0 1555m 95m 31m S 13.5 4.8 4:06.87 gnome-shell
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?

Programming :: Comparing String With Integer?

Sep 19, 2010

If I have a variable, say xvar, which can take both string and integer value and I want to perform an operation in following 2 conditions:1. Either xvar is null2. xvar equals 2[ -z "$xvar" ] || [ $xvar -eq 2 ] && <some-code>Doesn't seem to work if xvar takes string valuesI know that since I have no restriction on xvar, I can get away with string comparison in second test too, ie[ -z "$xvar" ] || [ "$xvar" = "2" ] && <some-code>
But, 'Sams teach yourself shell script in 24 hrs' says that [ expr1 -eq expr2 ], if either is string, it assumes 0 valueIs it true

Ubuntu :: Cli Comparing File Names Recursively?

Apr 24, 2011

I would like to use the command line to compare two directories against each other. I have two folders called music collection that have evolved over the last year on two separate computers. 90% of the two folders are the same, but there are small differences. I would like a solution that will print out all the differences so I can analyze them and choose what I want to do with them, before merging the two folders. for example.I would like some kind of output that shows the differences and where its located.

comparing MusicCollection1 and MusicCollection2
dif1.mp3 located in MC1/folder1 (this one I might want to keep and merge over)
dif2.mp3 located in MC2/folder3 (while this one I might realize does not exist in both folders because I deleted it for a reason)

I've looked at sort, uniq, and even tried scripting my own solution, but haven't come up with an elegant solution thus far. Its important that it is recursive because there are about 15 folders in Music collection and more folders under those 15.

Networking :: Comparing IPTables And Firewall Program?

Sep 10, 2010

I have to make my final exam on network & security, my task is to compare Iptables and a firewall program, yeah not a distribution. I use Archlinux so I'd like to continue use it for my project! Anyway my question is: which Network firewall could be the best one? I need this features:

- packet filtering
- HA (High Availability)
- Live (active) connection migration (if one fails...)
- Load balancing (not really important but...)

I know "many" firewalls but they all are distro. I need something to install on a linux machine (as said... better if I can run it directly on Archlinux!)
