Top Forums Shell Programming and Scripting Assign comma separated values to a variable Post 302994911 by rbatte1 on Wednesday 29th of March 2017 11:33:19 AM

You would be better to direct the output to the file with the done like this:-
Code:
while IFS="," read whatever
do
   something
done < input_file > output_file

You can append to the file rather than overwrite it if you need to, of course.

I don't see how you get the new output from what you had at the beginning. Perhaps you could show us some meaningful input too along with how you are getting it/calling it.

Are you getting a single, comma separated line from your database query? If there are no other messages, you could avoid the temporary file and read from the process.

For ksh try:-
Code:
db-query | IFS="," read var1 var2

For bash maybe try:-
Code:
IFS="," read var1 var2 < <(db-query)

They both depend on cleaning the output to be just a single line. For sqlplus you can add various things, such as the -S flag and ensure you have set heading off, set feedback off and possibly other things to turn off. Other databases have similar concepts to leave you just the raw output.


I hope that this helps,
Robin

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. AUTHOR
