I have two text files i want to compare the differances between but i dont wnat all of them, there is only about 30lines of relvent text i want to compare.
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?
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
Is there a way, besides writing a PERL program, to read each line one by one in file A and tell if this line also exists in file B? Can this be done via a shell script?
1. similar nos in both the file 1 and file 2 > output= File 3; 2. In file 1, but not in file 2 > out put= file 4; 3. In file 2, but not in file 1 > output = file 5;
The command sdiff is giving output with symbols > < | etc, and the such output file is not clear and ready to print. I want to print directly the output files. AND ALSO TELL ME WHERE I HAVE TO WRITE AWK PROGRAMS AND HOW TO RUN IT.
I want to compare 2 IP addresses, so that I may compare which is more/less "specific" or "restricted" than the other. So is there any function/library that may help in doing this comparison in C (on Ubuntu 10.10)?
I have two arrays of data, called data1.dat and data2.dat. each contains 60 data. What I want to do is to compare the data in each file and write the counting into bins. It goes like this. First, take the first data in data1.dat file and compare with the 60 data in data2.dat file. If there is any data which is same with the data in data1.dat then it count in bin. The total bins are also 60. Next it goes to the second data in data1.dat and compare with all the 60 data in data2.dat. If there is any data same then it add in second bin. And it repeats to all the data in data1.dat
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.
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.

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?
I have a file which provide the output of all the applications which started and running successfully. But it doesn't give the Error message of the applications which are failed. For example there are 5 applications (ABC,DEF,NMO,STO,XYZ) and application STO failed so I will get the following output (out.txt). content of out.txt file
Application ABC is Running Application DEF is Running Application NMO is Running Application XYZ is Running
I want to generate the text message based on the information on out.txt that STO application is Failed.
Is there a way to compare an array in a while conditions?
I have one array that contains the results of some search and if the script has found all the items, then it should stop, so my idea is to have a while loop � la:
I want to set the shortkey like win7,WIN+ --> is mean half the window in the right side and WIN+<- is mean half the window in the left side. It is helpful for comparing two documents.
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.
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!)
I'm trying to write a script that takes two arguments, the first argument is a number, and the second argument is a filename. The shell script should indicate if the file's size is BIGGER or SMALLER the number provided. this is what i have sofar, am i on the write track, i'm hoping its just a problem with my if command
if [ $1 -h $2 ] then echo "$1 is bigger than $2" else
I want to compare zone file counting and same name, not records etc of master and slave dns server so that i sure both server contains same copy of the files at a time. Any utility to compare such files in linux?
