Sed,nawk for inputfile and out put file same

Hi,

I am using sed and nawk command for replace/add/remove on file records.

But when I am using the inputfile name and directing output to the same inpu name file becomes empty.
I don't want to use to copy it to another file and move it back to original file.

Example:

sed 's/./,&/17' inputfile > inputfile--------->becomes inputfile empty

I want it to be work in a sigle comamnd can it be possible, please let me know.

TCA_CORRECT(1)							       HUGIN							    TCA_CORRECT(1)

NAME
tca_correct - Calculate transverse chromatic aberration SYNOPSIS
tca_correct [options] inputfile <inputfile> is the base name of 4 image files: <inputfile> Colour file to compute TCA parameters red_<inputfile> Red channel of <inputfile> green_<inputfile> Green channel of <inputfile> blue_<inputfile> Blue channel of <inputfile> The channel images must be colour images with 3 identical channels. If any of -R, -G, or -B is given, this file name is used instead of the derived name. Output: commandline arguments for fulla DESCRIPTION
Generates fulla command-line parameters for correction of transverse chromatic aberration (TCA) from sample photos. Ideal sample photos would have a lot of contrast over the entire image area, little saturated colour and no blown highlights. OPTIONS
-h Display help -l input file is PTO file instead of image -m method optimization method (0 normal, 1 newfit) -o optvars string of variables to optimize ("abcvde") -r Reset values (this will zero a,b,c,d,e params and set v to 10) makes sense only with -l option -s <scale> Scale for corner detection -n <number> number of points per grid cell (default: 10) -g <number> divide image in <number>x<number> grid cells (default: 10) -t num Remove all control points with an error higher than num pixels (default: 1.5) -v Verbose -w filename write PTO file -R <r> Use this file as red channel -G <g> Use this file as green channel -B <b> Use this file as blue channel AUTHORS
