I have a shell script with 2 run time arguments. During the execution if i got any error, then it needs to redirected to a error file and in console. Also both error and output to be redirected to a log file.
Error output is getting copied to err file and getting displayed in console too. But in log file the output and error message it getting redirected twice. I am not willing to use set -x option.
I have a file, let's say 1.jpg, and I have a text file that contains a list of filenames I would like to duplicate 1.jpg as (i.e., 2.jpg, 3.jpg, 4.jpg, etc.). The filenames that I want to create are all on separate lines, one per line.

XPACmdNew - create a new XPA public access point for commands
SYNOPSIS
#include <xpa.h>
XPA XPACmdNew(char *class, char *name);
DESCRIPTION
Create a new XPA public access point for commands that will share a common identifier class:name. Enter this access point into the XPA name
server, so that it can be accessed by external processes. XPACmdNew() returns an XPA struct.
It often is more convenient to have one public access point that can manage a number of commands, rather than having individual access
points for each command. For example, it is easier to command the ds9 image display using:
echo "colormap I8" | xpaset ds9
echo "scale log" | xpaset ds9
echo "file foo.fits" | xpaset ds9
then to use:
echo "I8" | xpaset ds9_colormap
echo "log" | xpaset ds9_scale
echo "foo.fits" | xpaset ds9_file
In the first case, the commands remain the same regardless of the target XPA name. In the second case, the command names must change for
each instance of ds9. That is, if a second instance of ds9 called DS9 were running, it would be commanded either as:
echo "colormap I8" | xpaset DS9
echo "scale log" | xpaset DS9
echo "file foo.fits" | xpaset DS9
or as:
echo "I8" | xpaset DS9_colormap
echo "log" | xpaset DS9_scale
echo "foo.fits" | xpaset DS9_file
Thus, in cases where a program is going to manage many commands, it generally is easier to define them as commands associated with the
XPACmdNew() routine, rather than as separate access points using XPANew().
When XPACmdNew() is called, only the class:name identifier is specified. Each sub-command is subsequently defined using the XPACmdAdd()
routine.
