i would like to enter (user input) a bunch of numbers seperated by space:
10 15 20 25
and use awk to print out any lines in a file that have matching numbers
so output is:
22 44 66 55 (10) 77 (20)
(numbers 10 and 20 matched for example)
is this possible in awk . im using gawk for... (5 Replies)
I am looking for a better way to match real numbers within a specified tolerance range. My current code is as follows:
if ($1 !~ /^CASE/) for(i=1;i in G;i++) if (G >= $5-1 && G <= $5+1)
{ print $1,$4,$5,J,G }
else { print $1,"NO MATCH" }
where $5 and G are... (3 Replies)
Hello to all,
I hope some awk guru could help me.
I have 2 input files:
File1: Is the complete database
File2: Contains some numbers which I want to compare
File1:
"NUMBERKEY","SERVICENAME","PARAMETERNAME","PARAMETERVALUE","ALTERNATENUMBERKEY"... (9 Replies)
Hi Experts,
I am finding difficulty to get exact match:

SUBNET_MASK="255.255.255.192"
BROADCAST_ADDRESS=""
INTERFACE_STATE=""
DHCP_ENABLE=0

Hi,
I'm trying to match a filename that could be called anything from vout001 to vout252 and was trying to do a small test but I'm not getting the result I thought I would..

In the awk below I am trying to match the value in $4 of file1 with the split value from $4 in file2. I store the value of $4 in file1 in A and the split value (using the _ for the split) in array. I then strore the value in $2 as min, the value in $3 as max, and the value in $1 as chr.
If A is... (6 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)
