Thanks for the explanation. i understand it now....but your code is not working ..it's giving me error while fetching every record:

Quote:
Syntax Error The source line is 1.
The error context is
NR == FNR { ref[$1] = $2; next } { if (substr($2, 1, 3) in ref) { dest = ref[substr($2, 1, 3)] "/" system("[ -d " dest " ] || mkdir -p " dest) >>> print <<< > (dest FILENAME) close(dest FILENAME) } else { dest = "others/" system("[ -d " dest " ] || mkdir -p " dest) print > (dest FILENAME) }}
awk: 0602-502 The statement cannot be correctly parsed. The source line is 1.

NAME
strcat, strncat - concatenate two strings SYNOPSIS
#include <string.h> char *strcat(char *dest, const char *src); char *strncat(char *dest, const char *src, size_t n); DESCRIPTION
The strcat() function appends the src string to the dest string, overwriting the null byte ('') at the end of dest, and then adds a ter- minating null byte. The strings may not overlap, and the dest string must have enough space for the result. The strncat() function is similar, except that * it will use at most n characters from src; and * src does not need to be null-terminated if it contains n or more characters. As with strcat(), the resulting string in dest is always null-terminated. If src contains n or more characters, strncat() writes n+1 characters to dest (n from src plus the terminating null byte). Therefore, the size of dest must be at least strlen(dest)+n+1. A simple implementation of strncat() might be: char* strncat(char *dest, const char *src, size_t n) { size_t dest_len = strlen(dest); size_t i; for (i = 0 ; i < n && src[i] != '' ; i++) dest[dest_len + i] = src[i]; dest[dest_len + i] = ''; return dest; } RETURN VALUE
The strcat() and strncat() functions return a pointer to the resulting string dest. CONFORMING TO
