[MITgcm-devel] testreport on sunos

[Oliver Jahn]

Hi Martin,

I think it should be
> tst=`echo $sVar $listVar | awk '{ for(i=2;i<=NF;i++){if($i==$1){t+=1}}; print t }'`
                                                                  ^^^^^^
since in gawk, ($i==$1) evaluates to 1 (true) if $i==$1 and 0 (false) 
otherwise.  testreport checks for tst to be equal to 1 (found one match) 
or not.  Don't have a sun awk to test this, though.

I think there is a program called nawk ('new awk') on sun that should 
behave similarly to awks on other systems (not just linux).

Oliver
