g1 is my function
I tested this in vain

Code:
if [ g1 $1 $2 $3 -ne 0 ];then

Code:
if [ $(g1 $1 $2 $3) -ne 0 ];then

Thanks for yours suggestions
I think function's in bash doesn't accept any variables.

So it should better to define those values before you call your function.

sth like..

Code:
function g1 () {
    echo $((a+b+c))
 }
 
 a=3
 b=4
 c=5
 
 if [ $(g1) -ne 0 ];then
 g1  #do what you want to do..
 fi

Regards,

pamu

DATEINTERVAL(3) 							 1							   DATEINTERVAL(3)

The DateInterval class

INTRODUCTION
Represents a date interval. A date interval stores either a fixed amount of time (in years, months, days, hours etc) or a relative time string in the format that DateTime's constructor supports. CLASS SYNOPSIS
DateInterval DateInterval Properties o public integer$y o public integer$m o public integer$d o public integer$h o public integer$i o public integer$s o public integer$invert o public mixed$days Methods o public DateInterval::__construct (string $interval_spec) o publicstatic DateInterval DateInterval::createFromDateString (string $time) o public string DateInterval::format (string $format) PROPERTIES
o $y - Number of years. o $m - Number of months. o $d - Number of days. o $h - Number of hours. o $i - Number of minutes. o $s - Number of seconds. o $invert - Is 1 if the interval represents a negative time period and 0 otherwise. See DateInterval::format. o $days - If the DateInterval object was created by DateTime.diff(3), then this is the total number of days between the start and end dates. Otherwise, $days will be FALSE. Before PHP 5.4.20/5.5.4 instead of FALSE you will receive -99999 upon accessing the prop- erty. PHP Documentation Group DATEINTERVAL(3)
