have a simple script for comparing two directories. I want to list all differences between this directories.
here is my function for compare:
function comp
{
for i in $1/*; do
if [ ! -e "$2/${i##*/}" ]; then
echo $i
[Code]....
in my script these two files are equal(my script ignored last time modified)

View 3 Replies View RelatedI 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 $1(file1)
If I have a variable, say xvar, which can take both string and integer value and I want to perform an operation in following 2 conditions:1. Either xvar is null2. xvar equals 2[ -z "$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 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 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 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

2. Produce the program that will output the text "Cool" every 20 seconds by setting a periodic task.

im trying to build a simple program for my C programming class, this is the source code
#include <stdio.h>
int main()
{
int length, width, length, height, area, perimeter;
perimeter = width + length + height;
area = width * length + heigth;
[Code]...
i dont see any error (you might)but every time i run it it runs but after it asks me to input for the width i do it but it doesn't take me to the length, it just stays blank until i input another value in the same place for the width, it asks me for 4 inputs in total i don;t know why, and after i run it different times it gives me different values for the perimeter and are. how can I fix this?

Each of em are plain text files with 1 word per line
Output should be something like:

I can call this routine and it works fine when I enter a valid name for $PROJ. If I enter an invalid name it goes to the else block and prints the statement. However, it does not call itself. Instead the script just exits.I've googled 'perl recursive subroutines' and the example don't appear to be doing anything different.

View 2 Replies View RelatedI am trying to create a function that takes a pair of a high and a low limit, and returns an arbitrary number between them. Below is my attempt to create a function that accomplishes this by checking to see if they are equal, and if not, subtracts a very small number from the high limit and returns the result.
View 2 Replies View RelatedThis is probably hopelessly ambitious as I'm not a C or C++ programmer (I normally like to stick to scripting languages like BASH or Perl). Basically I'm looking on good advice to get me started with writing a Application Dock with the functionality of the OSX dock but without the overly flamboyant graphics that have characterised the Linux versions.At the moment the closest I've found to what I would like is bbdock. However it falls well short of the functionality of what I would like.
What bbdock does is read a file to create an icon for the openbox dock/fluxbox slit/wmaker whatever that launches an application when first clicked, shows an little arrow when the application is running, and brings the application to the fore when clicked once running.Here's a screenshot of it doing just that.The drawback to bbdock is that it doesn't really look for running applications, only those launched from bbdock. So for example it wont notice if I've launched an instance of pcmanfm from the openbox menu. And therefore it obviously also doesn't add icons for other applications that are running.
What I would like to be able to do is detect new running applications and add a bbdock icon for them. Also to detect if an application already with a shortcut has been run and update it's status to show it's open. Probably have an up and down arrow to move the icons up and down when there are too many to fit on the screen. None of the above needs fancy animation. The fade to gray effect used by bbdock is quite nice and could probably be augmented with a fade in and out to grey to represent another action, say fading to grey and back when launching and greyed when iconified.So, my question is what do I need to get started doing this? Am I best using the pretty outdated bbdock wmaker dockapp style? What functions and libraries am I likely to need to achieve the effects I want? Are there any examples of how to monitor running applications (well windows and figure out what constitutes a new application) that I could look at for inspiration. Is there anyone who's into C++ for linux who would be interested in helping me out to get this small project working?
I want to create simple webcam effects filters. I am only interested in doing relatively simple image processing like blurring or averaging the color. I would like to create the filters in either C or Python.

I have this daemon I'm writing in Python, but I still a Python n00b. I've coded the part of the daemon that does the work, but not the part that receives messages. I need a simple system so that other processes on the same (Linux) computer can occasionally send text-string messages to the daemon (without needing to stay running all the time themselves). Once in the past we did something similar by (mis)using pyliblo to listen for OSC messages coming in on a certain port. That option isn't as workable here because the pyliblo interface (as near as I can tell) requires you to know in advance specifically what messages you are expecting, and forward them to specified functions, rather than just allowing you to generically process incoming messages as you see fit.

and this on the footer:
print "

so that i dont have to type everytime #!/usr etc i tried to do it this way but i get weird vim errors: header is a file that contains the header and footer $ vim hello.pl;header > is there another way to do it as a function in bash or some other one liner command?

View 14 Replies View RelatedI have a render script that uses several Blender 3D instances on several machines to co-render one still image. The image is split into squares of 64 x 64 pixels. In the end, I have like 200 image files, each one with a puzzle piece of the whole.
Now I would like to assembe these pieces into whole with PIL and Python, but so far cannot figure out how. I am new to PIL, but in imagemagick, a convert image1.png image2.png image3.png +append finalimage.png works a charme. But convert chokes on so many image files, so I need something automatic and scalable. I think that pictures are RGBA, so black should be the alpha channel and transparent.
I think I have to mention that the pieces are in the right position and that every piece has the original dimensions of the full picture, so it is not a problem figuring out where each piece should be. Just putting all the pictures on top of eachother and ignoring anything that is black would do the trick nicely.
How can I reach this with PIL? Which functions do I need for that? PIL does a lot of stuff, so finding my simple function is daunting.
