Hello,
Thanks, the solution provided worked...

Sorry for the missing input file.

Code:

 $ grep -e "Cyclomatic complexity" -e ";add;" inspect_64d_369980 | head -5
  Thread.cpp;176;25;Error;;3;NPD.FUNC.MUST;Error;add;-73966069;Pointer 'handle.operator->()' returned from call to function 'operator->' at line 176 may be NULL and will be dereferenced at line 176.;;Existing;;Analyze;2254;https://insight-review.html#goto:project= 64_d,pid=2254

Output (worked after changing from " to ')

Code:

 $ awk -F">20" "/Cyclomatic complexity/ && /;add;/{print \$1}" inspect_64d_369980 | awk '{print $NF}' | sort | tail -1
  65
  $ awk -F">20" '/Cyclomatic complexity/ && /;add;/{print $1}' inspect_64d_369980 | awk '{print $NF}' | sort | tail -1
  65
  $ var=`awk -F">20" "/Cyclomatic complexity/ && /;add;/{print \$1}" inspect_64d_369980 | awk '{print $NF}' | sort | tail -1`;echo $var
  65>20;;Existing;;Analyze;21190;https://insight-review.html#goto:project=64_d,pid=21190
  $var=`awk -F">20" '/Cyclomatic complexity/ && /;add;/{print $1}' inspect_64d_369980 | awk '{print $NF}' | sort | tail -1`;echo $var 
  65
  $ var=$(awk -F">20" '/Cyclomatic complexity/ && /;add;/{print $1}' inspect_64d_369980 | awk '{print $NF}' | sort | tail -1);echo $var
65

Thanks for the replies and solution Smilie

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
