Hi, I can see that You prefer AWK but the small program comm can also be very useful. I think it wouldn't barf on big files unless there are too many lines between diffs.
Example, this will show You the lines that does not exist in both files:
Code:
comm -3 oldfile.txt newfile.txt
So in the case of newfile.txt only having records removed, it would work.
Best regards,
Lakris

Hi,
I'm a newbie to scripting and am trying to compare two files using awk.
The files are exactly the same dimensions. Where the first file has 0's I would like to create an updated version of the second file which has the corresponding elements set to zero also.
eg:

How to convert this:
F1-R1 F1-R2 F1-R3 into a flat file for bash?? Each record
F2-R1 F2-R2 F2-R3
F3-R1 F3-R2 F3-R3
F4-R1 F4-R2 F4-R3is on one line with all fields for that record, put into an output file. The output file should look like this when converted:

FULLA(1) HUGIN FULLA(1)NAME
fulla - Correct lens distortion, vignetting and chromatic aberration
SYNOPSIS
fulla [options] inputfile(s)
DESCRIPTION
Apply radial or flat-field vignetting correction as well as geometrical radial distortion and transversal chromatic aberration correction.
fulla can be used to batch correct a large number of files. Radial distortion coefficients can be read from a PTLens database (only
database version 4.2 is supported).
Vignetting correction is done the same way as described in the nona script file documentation. Vignetting correction can be done based on
a flat-field or a radial scaling.
Vignetting correction by flat-field division:
I = I / c, c = flat-field / mean(flat-field)
Radial vignetting correction:
I = I / c, c = a + b*r^2 + c*r^4 + d*r^6
The radial distortion correction is identical to the one implemented by PanoTools:
r_new = a*r^4 + b*r^3 + c*r^2 + d*r [1]
Since transversal chromatic aberrations (TCA) leads to differently scaled objects in the red, green and blue channel, it can be corrected
by scaling the red and blue channel so that they match the green channel. Most applications, like Photoshop or Picture Window Pro offer TCA
correction by linear scaling. This is equal to varying the d parameter in equation [1].
See http://hugin.sf.net/tutorials/tca for a method to determine these parameters.
OPTIONS -g a:b:c:d
Radial distortion coefficient for all channels, (a, b, c, d)
-b a:b:c:d
Radial distortion coefficients for blue channel, (a, b, c, d). This is applied on top of the -g distortion coefficients, use for TCA
corr
-r a:b:c:d
Radial distortion coefficients for red channel, (a, b, c, d). This is applied on top of the -g distortion coefficients, use for TCA
corr
-p Try to read radial distortion coefficients (usually supplied using -g) from the PTLens database. The environment variable
PTLENS_PROFILE should point to the profile.txt file. Since newer version of the PTLens database are incompatible with fulla, download
the PTLens database from the hugin sourceforge website instead: http://www.sf.net/projects/hugin
-m Canon
Camera manufacturer, for PTLens database query. EXIF data inside JPEG files is read, if this option is not given
-n Camera
Camera name, for PTLens database query. EXIF data inside JPEG files is read, if this option is not given.
-l Lens
Lens name, for PTLens database query if not specified, a list of possible lenses is displayed
-d 50
Specify focal length in mm, for PTLens database query. EXIF data inside JPEG files is read, if this option is not given.
-s Do not rescale the image to avoid black borders.
-f filename
Vignetting correction by flat-field division
I = I / c, c = flat-field / mean(flat-field)
-c a:b:c:d
Radial vignetting correction by division:
I = I / c, c = a + b*r^2 + c*r^4 + d*r^6
-i value
Gamma of input data. used for gamma correction before and after flat-field correction
-t n
Number of threads that should be used during processing
-h Display help summary.
-o name
Set output filename. If more than one image is given, the name will be uses as suffix (default suffix: _corr)
-e value
Compression of the output files
For JPEG output: 0-100
For tiff output: DEFLATE, LZW
-v Verbose
