Full Discussion: SED on cygwin not working with Hex or Octal

Its not a problem with cygwin, sed or awk. Its the way inputfile is handled. The inputfile is handled line by line by sed and awk. So, that's why it didn't find <\/a>\\n\\t\\n\\t\\t<\/a> in a single line.

You may change your approach. Try this perl one-liner:

Code:
[user@cygwin ~]$ cat inputfile
hello
</a>

                </a>
world
[user@cygwin ~]$ perl -ne 'if(/^<\/a>/ .. /^\t\t<\/a>/) { (/^\t\t<\/a>/) && print "</a>\n" } else { print }' inputfile
hello
</a>
world

tca_correct

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
