awk Adding a Period at the end of a line
I started venturing in learning the art of using AWK/GAWK and wanted to simply added a period from line #11 to line #28 or to the end of the file if there is data. So for example:

Code:
11 	Centos.NM                         
12	dojo1                 
13	redhat.5.5.32Bit       
14	redhat.6.2.64Bit       
15	mandriva.9.2.32Bit     
16	RELEASE_WIN2003       
17	SaintBox-Ubuntu-x64     
18	SAINTexploitVM-x86      
19	SAINTVM-x64             
20	Ubuntu-12.04.x64        
21	bigbadwolf.x64          
22	WIN2003PATCHED          
23	WIN2003UNPATCH          
24	WIN-IQF3U12CJA5         
25	XPSP3PATCHED            
26	XPPROUNPATCHED          
27	WIN2012                 
28	WIN8_141

to

Code:
11 	Centos.NM.                         
12	dojo1.                 
13	redhat.5.5.32Bit.       
14	redhat.6.2.64Bit.       
15	mandriva.9.2.32Bit.     
16	RELEASE_WIN2003.       
17	SaintBox-Ubuntu-x64.     
18	SAINTexploitVM-x86.      
19	SAINTVM-x64.             
20	Ubuntu-12.04.x64.        
21	bigbadwolf.x64.          
22	WIN2003PATCHED.          
23	WIN2003UNPATCH.          
24	WIN-IQF3U12CJA5.         
25	XPSP3PATCHED.            
26	XPPROUNPATCHED.          
27	WIN2012.                 
28	WIN8_141.

This is what I had so far:

Code:
awk '{ NR==11,NR==28 print $0 "." }' < test_file 
awk: { NR==11,NR==28 print $0 "." }
awk:         ^ syntax error
awk: { NR==11,NR==28 print $0 "." }
awk:                 ^ syntax error

dpkg-awk

DPKG-AWK(1)						      General Commands Manual						       DPKG-AWK(1)

NAME

       dpkg-awk - Utility to read a dpkg style db file

SYNOPSIS

       dpkg-awk [(-f|--file) filename] [(-d|--debug) ##] [(-s|--sort) list] [(-rs|--rec_sep) ??] '<fieldname>:<regex>' ... -- <out_fieldname> ..

DESCRIPTION

       dpkg-awk  Parses  a  dpkg status file (or other similarly formatted file) and outputs the resulting records.  It can use regex on the field
       values to limit the returned records, it can also be told which fields to output, and it can sort the matched fields.

OPTIONS

       -f filename
       --file filename
	      The file to parse.  The default is /var/lib/dpkg/status.

       -d [#]
       --debug [#]
	      Each time this is specified, it increased the debug level.

       -s field(s)
       --sort field(s)
	      A space or comma separated list of fields to sort on.

       -n field(s)
       --numeric field(s)
	      A space or comma separated list of fields that should be interpreted as numeric in value.

       -rs ??
       --rec_sep ??
	      Output this string at the end of each output paragraph.

       -h
       --help Display some help.

       fieldname
	      The fields from the file, that are matched with the regex given.	The fieldnames are case insensitive.

       out_fieldname
	      The fields from the file, that are output for each record.  If the first field listed begins with ^, then the list  of  fields  that
	      follows will NOT be output.

BUGS

       Be  warned  that  the author has only a shallow understanding of the dpkg packaging system, so there are probably tons of bugs in this pro-
       gram.

       This program comes with no warranties.  If running this program causes fire and brimstone to rain down upon the earth, you will be on  your
       own.

       This program accesses the dpkg database directly in places, querying for data that cannot be gotten via dpkg.
