Try this:

Code:
awk -v cord=${cord:-25} '
    /variableStep/ {
        if( !printed++ )          # allows multiple headers in the input 
            print;
        next
    }
    {
        if( $1 > last+cord)      # current isn't in sequence, catch up
            for( i = last+cord; i < $1; i+= cord )
                printf( "%d 0\n", i );
        printf( "%s %s\n", $1, $2 );
        last = $1;
    }

NAME
detectups - UPS detection/powerd configuration generator SYNOPSIS
/sbin/detectups [tty] DESCRIPTION
detectups monitors the serial port connected to an UPS device and will attempt to determine the method of UPS notification of power outage. It will ask you to remove the power cord from the wall to the UPS, or push the UPS's test button. It will then determine what all has hap- pened and ask to generate a config file based on your UPS and cable configuration. detectups needs to watch a tty with modem control prop- erties. Please refer to the powerd documentation for further information. ARGUMENTS
Serial-Device Some serial port that is not being used by some other device, and does not share an interrupt with any other serial port. /etc/powerd.conf FILES
/etc/powerd.conf powerd configuration file that detectups generates /etc/inittab init is what actually issues the shutdown SEE ALSO
powerd(8), shutdown(8), wall(1), inittab(5). AUTHOR
