Thanks for providing me the solution in arriving at the desired output.
I got the correct output.
As I don't have much exp. in Shell scripting, I just want to know what this line of code does in the execution :
mv $"${TFILE}.tmp" "$TFILE"
renaming the file back to original file name?. And here one thing I want to understand about why it is required to create the temp file.
Thanks.,
Vinay

Is it possible to use two arrays in a loop?
Basically what I am trying to do is iterate through the elements in an array, and, based on a condition, use the current position in the array to point to that index in the array. Here's the loop structure I'm looking for:

wsncasecmp
wstring(3C) Standard C Library Functions wstring(3C)
NAME
wstring, wscasecmp, wsncasecmp, wsdup, wscol - Process Code string operations
SYNOPSIS
#include <widec.h>
int wscasecmp(const wchar_t *s1, const wchar_t *s2);
int wsncasecmp(const wchar_t *s1, const wchar_t *s2, int n);
wchar_t *wsdup(const wchar_t *s);
int wscol(const wchar_t *s);
DESCRIPTION
These functions operate on Process Code strings terminated by wchar_t null characters. During appending or copying, these routines do not
check for an overflow condition of the receiving string. In the following, s, s1, and s2 point to Process Code strings terminated by a
wchar_t null.
wscasecmp(), wsncasecmp()
The wscasecmp() function compares its arguments, ignoring case, and returns an integer greater than, equal to, or less than 0, depending
upon whether s1 is lexicographically greater than, equal to, or less than s2. It makes the same comparison but compares at most n Process
Code characters. The four Extended Unix Code (EUC) codesets are ordered from lowest to highest as 0, 2, 3, 1 when characters from different
codesets are compared.
wsdup()
The wsdup() function returns a pointer to a new Process Code string, which is a duplicate of the string pointed to by s. The space for the
new string is obtained using malloc(3C). If the new string cannot be created, a null pointer is returned.
wscol()
The wscol() function returns the screen display width (in columns) of the Process Code string s.
