I have a pipe delimited file with 1 million records. I need to validate each line by counting the number of delimiters, if any line fails to have the specified number of delimiters, taat line has to be sent to a reject file.
"sent" to a reject file is somewhat ambiguous, do you mean write a copy of the line to the reject file or delete it from the original and write it to the reject file?
You can use the split shell command to split the file into manageable chunks if it is too big for awk. See the man file for split: -
Hi,

thanks

wcscspn
WCSCSPN(3) Linux Programmer's Manual WCSCSPN(3)NAME
wcscspn - search a wide-character string for any of a set of wide characters
SYNOPSIS
#include <wchar.h>
size_t wcscspn(const wchar_t *wcs, const wchar_t *reject);
DESCRIPTION
The wcscspn() function is the wide-character equivalent of the strcspn(3) function. It determines the length of the longest initial seg-
ment of wcs which consists entirely of wide-characters not listed in reject. In other words, it searches for the first occurrence in the
wide-character string wcs of any of the characters in the wide-character string reject.
RETURN VALUE
The wcscspn() function returns the number of wide characters in the longest initial segment of wcs which consists entirely of wide-charac-
ters not listed in reject. In other words, it returns the position of the first occurrence in the wide-character string wcs of any of the
characters in the wide-character string reject, or wcslen(wcs) if there is none.
