Do I need to maintain this manually and update everytime the "text file" is updated?
Of course not, that's what touch is for. It creates and/or updates its own temporary file.
It just uses the temporary file as a timestamp, "refreshing" it after it processes the data. If the data file is older than the timestamp file, then it's been processed already. If it's newer than the timestamp, it arrived after the last batch of processing.
You don't have to trust me, try it for yourself. Type these into your shell:

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
