Full Discussion: Read 1-line file and separate into multiple variables

If we assume records separated by semicolon, 1 to 17 fields should be something like:

Code:
f1	100518-213;
f2	John+Smith;
f3	jsmith@gmail.com;
f4	212-555-1212;
f5	js1234;
f6	OTHER;
f7	Universal+Exports;
f8	Normal;
f9	I+need+this+request+completed+as+soon+as+possible+please.;
f10	Our+department+needs+these+added+for+access+to+new+servers;
f11	Please+update+our+group+when+completed.;
f12	All 13-State 9-State;
f13	Add Add Delete;
f14	Router+Access Mail Other;
f15	;
f16	10.1.1.1%2F24 192.168.1.1 10.2.1.1%2F22;
f17	23 25 80


Some questions:

how the multiple records (in the last 6 as you said) are recognized? separated by space always?

field 15 is null. is that a typo or fields can be null?

what is the final purpose to those variable? how do you going to use them?
perhaps your purpose can be solved in awk itself. (until it is really necessary to go back to the shell.)

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.
