Hammer & Screwdriver Issue with awk command between Linux and Solaris

Hi,

Here is the output using bash profile on Linux

Code:
 uptime
 04:59:14 up 16 days,  4:48,  2 users,  load average: 1.00, 1.00, 1.20

Here is the output using bash profile on Solaris

Code:
uptime
  4:00am  up 84 day(s), 22:21,  3 users,  load average: 0.09, 0.10, 0.12

Now, I m looking for a generic command to extract the average CPU Load which is the third column highlighted in BOLD RED

I tried the below command

Code:
uptime | awk -F" ,"  '{print $(NF-2)}' | cut -d ',' -f1

This works fine on Solaris but fails on Linux with the below error

Code:
awk: cmd. line:1: (FILENAME=- FNR=1) fatal: attempt to access field -1

Can you please help with a solution ?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
