The for construct is used to iterate through a list or repeatedly evaluate an expression. Using it for one single value is at least, hmmm, questionable, as the loop variable is set to exactly that single value.
Thanks again RudiC, I understand now that loop is questionable for single value.
I had different problem scenarios with IF statement. Can any expert please enlighten me on the difference with these scenarios. Thank you.
1st Scenario:
testdate=`date +%Y%m`
test=`cat /var/log/database0.$testdate*.log | grep "Errors found during processing" | tail -10`

div
DIV(3) Linux Programmer's Manual DIV(3)NAME
div, ldiv, lldiv, imaxdiv - compute quotient and remainder of an integer division
SYNOPSIS
#include <stdlib.h>
div_t div(int numerator, int denominator);
ldiv_t ldiv(long numerator, long denominator);
lldiv_t lldiv(long long numerator, long long denominator);
#include <inttypes.h>
imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
lldiv():
_XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or cc -std=c99
DESCRIPTION
The div() function computes the value numerator/denominator and returns the quotient and remainder in a structure named div_t that contains
two integer members (in unspecified order) named quot and rem. The quotient is rounded toward zero. The result satisfies quot*denomina-
tor+rem = numerator.
The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing numbers of the indicated type and returning the result in a structure of
the indicated name, in all cases with fields quot and rem of the same type as the function arguments.
RETURN VALUE
The div_t (etc.) structure.
CONFORMING TO
SVr4, 4.3BSD, C89. C99. The functions lldiv() and imaxdiv() were added in C99.
EXAMPLE
After
div_t q = div(-5, 3);
the values q.quot and q.rem are -1 and -2, respectively.
