Tweaked for my system
Hi,
I made small change to the code posted by Ygor...and that will apply to solution by Aigles too (remember, my problem is reassigning $4 doesnt modify $0). Heres the changed code:
awk 'BEGIN{FS=":"}{str=""; for(j=1;j<=NF;++j) str=sprintf("%s%s",str,$j)} (v[str]=="")||(v[str]>$4){v[str]=$4;a[str]=$0}END{for(i in a)print a[i]}' file1
Here are the tweaks:
(1) Now I have a new variable "str" - this doesnt have the 4th column values
(2) In the condition part, now I check for (v[str]=="") instead of (!v[str]) --- the latter throws an error on my system.
Thanks to everyone for the effort....
Regards, Abhishek

curs_instr
curs_instr(3X) curs_instr(3X)
NAME
instr, innstr, winstr, winnstr, mvinstr, mvinnstr, mvwinstr, mvwinnstr - get a string of characters from a curses window
SYNOPSIS
#include <curses.h>
int instr(char *str);
int innstr(char *str, int n);
int winstr(WINDOW *win, char *str);
int winnstr(WINDOW *win, char *str, int n);
int mvinstr(int y, int x, char *str);
int mvinnstr(int y, int x, char *str, int n);
int mvwinstr(WINDOW *win, int y, int x, char *str);
int mvwinnstr(WINDOW *win, int y, int x, char *str, int n);
DESCRIPTION
These routines return a string of characters in str, extracted starting at the current cursor position in the named window. Attributes are
stripped from the characters. The four functions with n as the last argument return a leading substring at most n characters long (exclu-
sive of the trailing NUL).
RETURN VALUE
All of the functions return ERR upon failure, or the number of characters actually read into the string.
X/Open defines no error conditions. In this implementation, if the window parameter is null or the str parameter is null, a zero is
returned.
NOTES
Note that all routines except winnstr may be macros.
PORTABILITY
SVr4 does not document whether a length limit includes or excludes the trailing NUL.
The ncurses library extends the XSI description by allowing a negative value for n. In this case, the functions return the string ending
at the right margin.
SEE ALSO
curses(3X).
