Hi,

I've a file ImageSizeDetails.txt with the following contents:

Code:
Image Name:   swncd 01.10.00.04
Created:      Wed Jan  9 14:05:48 2013
Image Type:   ARM Linux Multi-File Image (gzip compressed)
Data Size:    7351011 Bytes = 7178.72 kB = 7.01 MB
Load Address: 00008000
Entry Point:  00008000
Contents:
   Image 0: 1672879 Bytes = 1633.67 kB = 1.60 MB
   Image 1: 5678119 Bytes = 5545.04 kB = 5.42 MB

I need to extract the size of Image 0 in bytes (i.e) 1672879 alone& save it in a variable. Kindly help me with a shell script

image::exiftool::shortcuts

Image::ExifTool::Shortcuts(3pm) 			User Contributed Perl Documentation			   Image::ExifTool::Shortcuts(3pm)

NAME

       Image::ExifTool::Shortcuts - ExifTool shortcut tags

SYNOPSIS

       This module is required by Image::ExifTool.

DESCRIPTION

       This module contains definitions for tag name shortcuts used by Image::ExifTool.  You can customize this file to add your own shortcuts.

       Individual users may also add their own shortcuts to the .ExifTool_config file in their home directory (or the directory specified by the
       EXIFTOOL_HOME environment variable).  The shortcuts are defined in a hash called %Image::ExifTool::UserDefined::Shortcuts.  The keys of the
       hash are the shortcut names, and the elements are either tag names or references to lists of tag names.

       An example shortcut definition in .ExifTool_config:

	   %Image::ExifTool::UserDefined::Shortcuts = (
	       MyShortcut => ['createdate','exif:exposuretime','aperture'],
	       MyAlias => 'FocalLengthIn35mmFormat',
	   );

       In this example, MyShortcut is a shortcut for the CreateDate, EXIF:ExposureTime and Aperture tags, and MyAlias is a shortcut for
       FocalLengthIn35mmFormat.
