Not real clear what you are after here. Some sssumptions I've made:
1. The order the files are output should remain the same as defined in config file
2. Multiple replaces may appear for each file
3. Replace tag (eg @Phone@) may have different values for different files
Here is the solution in awk:

First, thanks for the help in previous posts... couldn't have gotten where I am now without it!
So here is what I have, I use AWK to match $1 and $2 as 1 string in file1 to $1 and $2 as 1 string in file2. Now I'm wondering if I can extend this AWK command to incorporate the following:

I have very limited coding skills but I'm wondering if someone could help me with this. There are many threads about matching strings in two files, but I have no idea how to add a column from one file to another based on a matching string.
I'm looking to match column1 in file1 to the number... (3 Replies)
Hi Freinds,
i have a file1 as below

file2 contains lakhs of records and not in sorted order
i want to retrive only the records from file2 by searcing the first field of file 1

I am trying to use awk to find all the $2 values in file2 which is ~30MB and tab-delimited, that are between $2 and $3 in file1 which is ~2GB and tab-delimited.
I have just found out that I need to use $1 and $2 and $3 from file1 and $1 and $2of file2 must match $1 of file1 and be in the range... (6 Replies)
Trying to use awk to:
update $2 in file2 with the $2 value in file1, if $1 in file1 matches $13 in file2, which is tab-delimeted. The $2values may already be the same so in that case nothing happens and the next line is processed.
There are exactly 4,605 unique $13 values. Thank you :).

In the awk below I am trying to set/update the value of $14 in file2 in
bold, using the matching NM_ in $12 or $9 in file2
with the NM_ in $2 of file1.
The lengths of $9 and $12 can be variable but what is consistent is the start pattern
will always be NM_ and the end pattern is always ;... (2 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)
