Hi All... thanks for all your amazing replies Smilie

@kato - ur code is working absolutely fine Smilie

@sk1418 - i liked ur code for the output format... but when i tried to use it in my script it is giving error for "column -s" command

error diaplayed is :
./log_test4.ksh[23]: column: not found

i also tried to man column but it seems it is not supported here

pht025a2:/home/oper/pk264w/log_script> man column
No manual entry for column.

This is what i used...

awk '{print "|"$4"#|"$7"#|"$9"# |"}' mail_log_status.log | column -s"#" -t | awk 'BEGIN{line=""}{l=length($0);if(length(line)
==0)for(i=1;i<l;i++)line=line"-";print line;print $0}END{print line}'

WCWIDTH(3)						   BSD Library Functions Manual 						WCWIDTH(3)

NAME
wcwidth -- number of column positions of a wide-character code LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wchar.h> int wcwidth(wchar_t wc); DESCRIPTION
The wcwidth() function determines the number of column positions required to display the wide character wc. RETURN VALUES
The wcwidth() function returns 0 if the wc argument is a null wide character (L''), -1 if wc is not printable, otherwise it returns the number of column positions the character occupies. EXAMPLES
This code fragment reads text from standard input and breaks lines that are more than 20 column positions wide, similar to the fold(1) util- ity: wint_t ch; int column, w; column = 0; while ((ch = getwchar()) != WEOF) { w = wcwidth(ch); if (w > 0 && column + w >= 20) { putwchar(L' '); column = 0; } putwchar(ch); if (ch == L' ') column = 0; else if (w > 0) column += w; } SEE ALSO
iswprint(3), wcswidth(3) STANDARDS
The wcwidth() function conforms to IEEE Std 1003.1-2001 (``POSIX.1''). BSD
