Help needed with awk external variable
I'm trying to get the universities result data into different file, where the $9 contains unversity field and field7,4 & 5 contains the keys to sort the students by marks. How to use uni variable to match against $9 inside awk?
Code:
c=0
for uni in `cat /tmp/global_rank| awk -F ',' '{print $9}'|sort |uniq`
do

awk  -F ','  -v  'VAR=$uni {
if ($9 == VAR)
print 
}' /tmp/global_rank | sort -nr -t","  -k7,7 -k4,4 -k5,5 > /tmp/university_${c}.csv
c=`expr $c + 1`
done

Thanks for the help!

dpkg-ruby

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

NAME

       dpkg-ruby - Utility to read a dpkg style db file, dpkg-awk clone

SYNOPSIS

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

DESCRIPTION

       dpkg-ruby Parses a dpkg status file(or other similarly formated file) and outputs the resulting records.  It can use  regex  on	the  field
       values to limit the returned records, and it can also be told which fields to output.  As another option, 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 outputted for each record.  If the first field listed is begins with ^, then the list that fol-
	      lows are fields NOT to be outputted.

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 our
       own.

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