General :: Comparing Resources Using Top?

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 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?

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:

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?

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

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 want a distro I can run on my very weak netbook, and perhaps on one or two other of my other computers as well. Netbook is an Asus eeePC 900SD (Celeron 800mhz, 512MB RAM, 8GB SDD, 1024x600 screen resolution), very slow with some distros, but nimble with others.
I've tried:
Ubuntu Netbook Remix (EasyPeasy), Leeenux, JoliCloud: too resource hungry on this machine, too much storage consumed just for the OS. Peppermint OS - pros: works well, nice, very few bugs, fast.cons: space requirements, memory requirements make it a bit tight, cloud apps are slower than locally installed ones, the permanent inclusion of a paid-subscription cloud app, and fascist support forum moderators. a bit overweight, and way too cloud-centric - many of the cloud apps are on unreliable servers and not always available or slow down your netbook to a crawl while it waits for some executable code to come off the web. Puppeee version 1.0 (and Fluppy for all netbooks), works very well, very fast, in little RAM with little disk space required. Some may not like the overcrowded menus and their structure that's inherited from the parent Puppy. Puppy 5.1: works very well compared to the 4.3 series. wifi works now. But same menu comments as for Puppeee. Slitaz: at 30MB for the iso, it sounded promising, and the interface is very nice, much nicer than any of the other minimalistic distros. but Wifi? no help on the horizon.
AntiX: some stuff just didn't work properly, including Wifi WPA. but it looked real good. For the space and memory requirements look to Peppermint. TinyMe2010: this is the size of Puppy, and polished like Peppermint. Based on a slimmed-down Unity, it is still in beta, the installer won't install from USB stick. If you have a CD to install from this is a great distro! Lets hope they fix the USB issue soon! Very promising... keep a watch on this one.
[Code]...
I've tried dozens of distros, and find it frustrating to deal with the various crippling flaws of some distros and the egos of the assemblers of other distros (where they can easily fix something but refuse to because they prefer an older faulty way). I am at my whit's end here. Please help me someone.
From us Noob's point of view: the new re-release of Windows XP for Legacy computers with only 64MB of RAM, it may be time to re-visit our thinking that minimalistic Linux distros are the only kid on the block for those slower machines with less resources. Time to get back to the drawing board and make these a little more user-welcoming. ;-)

I don't know about your computer but when mine is working properly no process is sucking 95%+ over time. I would like to have some failsafe that kills any processes behaving like that. This comes to mind because when I woke up this morning my laptop had been crunching all night long on a stray chromium child process.
This can probably be done as a cron job, but before I make it a full time job creating something like this I'd thought I should check here. :) I hate reinventing the wheel.

I have a Ubuntu hosting a Windows XP box (using VirtualBox). The Windows XP box is connected to work using Check Point VPN-1. Essentially this enables me to go to my Windows box and do something like ping comp-at-work and it just works.
I would like to access the VPN resources from the Linux host though. The Windows guest is only there because the VPN client isn't working in Linux. If I could somehow ssh from the Linux host right into my computer at work (using remote desktop would also be great), that would save me a lot of round trips between my Linux host and the Windows guest.

If I forget to close a file, a socket or any other resource in a Linux process, and the the process terminates, will those resources be freed? Is there a difference if the process terminates normally or is killed?

I've got a ~/.Xdefaults that has a specific color theme defined for Xorg, and this works. I've got a ~/.XdefaultsNew that specifies an alternate color theme. Xorg starts and loads ~/.Xdefaults which is correct. After running some applications, I run
xrdb ~/.XdefaultsNew
This overrides all my X resources to the new defined values (correctly). If I open a new window, the theme is seen correctly. However, all the previously opened windows retain the original theme.Is there a way to force X to "re-theme" all windows it is managing with the currently loaded X resources?

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 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.

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

I would like to ask opinion from perl experts.
I want to compare 2 files and show the differences in a text file.
For example, if i open File A an B in notepad
File A:
File B:
Quote:
line3 is missing in File B
So if I did a File compare (line by line), the differences will be in line3, line4, line5, line 6.
But I dont want it to be like that.
I want it to be like this

Can Text:: Diff able to perform the work.

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.
