New at scripting awk with variable
I am trying to write a shell script that will add a date to and awk command from the command prompt.

here is the line I am having difficulties.

Code:
zgrep -i playback $dir/$1-*-errors.out.gz  |cut -d '|' -f 1,11,12,15 | awk -v start=${start} -v end=${end} -F '|' '{$1>=start  && $1 <=end} {print $2 ,$3 ,$4}' | sort -n  |uniq

The logs are in epoc so I added this to the script


Code:
start=`date --date="$2" +%s000`
end=`date --date="$3" +%s000`

to execute the command...
Code:
#Get_Error.sh  20151201 "20151201 05:11:00" "20151201 07:50:00"

Not sure how to add the variable to the awk command without it braking. If I run it manually with epoc timestamps it runs fine.



Any help would be appreciated.

Thanks

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
