Hello Everybody!!!!!!!!! Request you to help me with the below mentioned issue:
I have 2 files say,
File 1:
a|4|7
b|3|2
c|8|8
d|8|9
File 2:
a|4|6
b|2|2
c|8|8
d|9|8
The third file(output file) should have:
Data mismatch in row 1 column 3
Data mismatch in row 2 coumn 2
Data... (3 Replies)

Hi,
I'm new to perl and i have to write a perl script that will compare to log/txt files and display the differences. Unfortunately I'm not allowed to use any complied binaries or applications like diff or comm.

Hi

I have two text files which has the file size, timestamp and the file name. I need to compare these two files and get the differences in the output format. Can anyone help me out with this.

I want to compare 2 files and create third file with uncommon content.
e.g.
file1
ajay suhas tom nisha vijay mahish
file2
ajay suhas tom nisha
expected output file content
vijay mahish
Is it possible in single command ?
Thanks,

I have 2 files that need to be compared. Email the differences if something is different and don't email if nothing is different. One or both of the files could be empty. One or both could have data in them.

backup.doc.$(date +%y%m%d) file size is 0
backup.doc.$(TZ=CST+24... (4 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)
