Search and replace the last field
Hi All,

Seeking for your assistance on how to search and replace the last field/column. please see sample below:

Code:
inputfile1.csv
="8923523434",="543623534"="afd23535623",="100"="200"
="8923523431",="543623536"="afd23535626",="101"="201"
="8923523432",="543623538"="afd23535622",="104"="202"

sample expected output
Code:
inputfile1.csv
="8923523434",="543623534"="afd23535623",="100200"
="8923523431",="543623536"="afd23535626",="101201"
="8923523432",="543623538"="afd23535622",="104202"

it will replace the "=" in the last field of the data.

what i did was:

Code:
awk3=`awk -F "," '{print $4}'  inputfile1.csv | sed -e 's/="//g' -e s'/"//g'`

while IFS=, read a b c d; do
d=$(echo "${awk3}; $d)
echo "$a,$b,$c,$d"
done < inputfile1.csv > final.csv

the problem is it will print the whole records in $d i think due to awk. i don't know else what to do please help.

Please advise,

Thanks,

jifty::action::record::search

Jifty::Action::Record::Search(3pm)			User Contributed Perl Documentation			Jifty::Action::Record::Search(3pm)

NAME

       Jifty::Action::Record::Search - Automagic search action

DESCRIPTION

       The class is a base class for Jifty::Actions that serve to provide an interface to general searches through Jifty::Record objects. To use
       it, subclass it and override the "record_class" method to return the fully qualified name of the model to do searches over.

METHODS

   arguments
       Remove validators from arguments, as well as ``mandatory'' restrictions. Remove any arguments that render as password fields, or refer to
       collections.

       Generate additional search arguments for each field based on the following criteria:

       "text", "char" or "varchar" fields
	   Create "field"_contains and "field"_lacks arguments

       "date", or "timestamp" fields
	   Create "field"_before, "field"_after, "field"_since and "field"_until arguments.

       "integer", "float", "double", "decimal" or "numeric" fields
	   Generate "field"_lt, "field"_gt, "field"_le and "field"_ge arguments, as well as a "field"_dwim field that accepts a prefixed
	   comparison operator in the search value, such as ">100" and "!100".

   take_action
       Return a collection with the result of the search specified by the given arguments.

       We interpret a "undef" argument as SQL "NULL", and ignore empty or non-present arguments.
