Hi, I came across with this line "set -x" in the beginning of a script, but i can't find one logic reason for this... should be something else after, i think.... anyone can help?

Hello,
So I sorted my file as I was supposed to:
sort -n -r -k 2 -k 1 file1 | uniq > file2
and when I wrote
> cat file2
in the command line, I got what I was expecting, but in the script itself
...
sort -n -r -k 2 -k 1 averages | uniq > temp
cat file2
It wrote a whole... (21 Replies)

echo ${line} | perl -pe 's/(\d+)/localtime($1)/e'

how can i efficiently re-code the above?
also, no matter how i run this, i'm not getting the current/correct date. the contents of the "text.xt" looks like this:

I wrote by accident:
cd .
and even hit ENTER.
Then I realized this is probably the most useless command that you can imagine. Yes, perhaps it could assert that there is still a working filesystem, but I am not sure about it.
What do you think?
Can you think of any more useless commands? :) (6 Replies)

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
