Hi Guys,
Requirement: Want to compare two files, if the the content of both files is same then show "Good result" else Show "Bad Result"
I am using the following logic
if( cmp -s a b = 0 )
then
echo "Good result"
else echo "Bad result"

Hi,
I need to compare 2 files based on the first field in each file and output the differences to a new file.
example File 1 and File 2 both have first field as Number ie:
File 1
1252652355
1859553322
1778899562
File 2
1252652355

So I would expect File 3 to... (2 Replies)

how can i unix compare two files??
var1 = 6499 7328 6351 7583 7573
var2 = 6499 7328 6351 7583 7777
i did:
diff $var1 $var2
and i got the output:
1c1
< 6499 7328 6351 7583 7573
---
> 6499 7328 6351 7583 7777
what can i do with it? and what does it tell me?? how can i knoe that... (2 Replies)

Hi,
I have two files
File1 Contents:
abc
dcf
sdc
File2 Contents:
dcf
sdc
erg
Now my program should return the contents existing in File1 but not in File2. In this case output shoud be "abc" as abc is not available in File 2. It should not return "erg" by saying it is... (4 Replies)

I have a file containing the below data obtained after running a diff command
> abc 10
< abc 15
> xyz 02
<xyz 05
.....
Does anyone know how i can obtain output like :
previous value of abc is 10 and present value is 15
similarly for all the comparisons in the text file (10 Replies)

SYNOPSIS
numm-run FILE
DESCRIPTION
Frequency makes for a meaningful description of many audio signals. We can use numpy's fourier analysis to compute spectra from the micro-
phone and display the results visually. We will break down the process into smaller parts: baby steps...
First, create and save a skeletal file that moves a line across the screen:
idx = 0
def video_out(a):
global idx
a[:,idx] = 255
idx = (idx + 1) % a.shape[1]
def audio_in(a):
pass
Save this snippet and run it with numm-run.
We will use the numpy.fft module for our analysis. First we define a function to get a particular frequency from the fourier transform:
import numpy as np
def get_freq(fourier, frequency):
freqs = np.fft.fftfreq(len(fourier), 1/44100.0)
nearest = (abs(freqs - frequency)).argmin()
return abs(fourier[nearest])
Next, we hook up this function to audio input from the microphone. A frequency bin is chosen on a log scale for each row on the screen to
display a spectogram. In total:
import numpy as np
idx = 0
recent_audio = np.zeros(4096, np.int16)
recent_video = np.zeros((240,320,3), np.uint8)
freq_bins = np.exp2(np.linspace(np.log2(27000),np.log2(27),240))
def get_freq(fourier, frequency):
freqs = np.fft.fftfreq(len(fourier), 1/44100.0)
nearest = (abs(freqs - frequency)).argmin()
return abs(fourier[nearest])
def video_out(a):
global idx
fourier=np.fft.fft(recent_audio)
values =np.array([get_freq(fourier,X) for X in freq_bins])
recent_video[:,idx,1] = (values/10000).clip(0,255)
idx = (idx + 1) % a.shape[1]
a[:] = np.roll(recent_video, -idx, axis=1)
def audio_in(a):
recent_audio[:] = np.roll(recent_audio, len(a))
recent_audio[:len(a)] = a.mean(axis=1)
