Code:

awk -v v_start="$start" -v v_end="$end" '$0~v_start{flag=1;}$0~v_end{print;flag=0}flag'  Input_file
OR
awk -v v_start="$start" -v v_end="$end" '$0~v_start{flag=1;print;next}$0~v_end{print;flag=0}flag'  Input_file
OR
awk -v v_start="$start" -v v_end="$end" '$0~v_start{flag=1;};flag;$0~v_end{flag=0}'  Input_file

Output will be as follows in above all 3 solutions.

Code:

one
two
three
four
five
ten

Thanks,
R. Singh

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
