What you don't seem to recognize is that you have a mixture of processing an array of id values along with getting a single scalar result value. And, after getting an array of id values and getting a single result value you are then using a for loop to process the values in the id array without getting result values associated with each element of the id array. That just can't work.

I don't follow the logic of what your script is trying to do, and the inconsistent indentation in your script doesn't help. This is totally untested, but might provide an idea for a way to move forward on your project. Note that (unlike Aia's suggestion and your code), this gathers one ID at a time rather than an array of IDs. Otherwise, I think this code follows the intended flow of your code more closely than Aia's suggestion. But, I may have misread the intent of your code:

Code:

#!/bin/bash
csv="getCSV.txt"
logf="C:\Users\cmccabe\Desktop\wget\match.txt"

# url download
printf "establishing connection and downloading file, please wait"

cd 'C:\Users\cmccabe\Desktop\wget'
curl -# -o "$csv" http://xxx.xx.xxx.xx/file/name.csv

# enter user-defined id
while read -r -p'please enter id (empty line or ctl-d when done): ' id
do	# check to make sure something entered
	if [ -z "$id" ]
	then 	printf '\nNo ID supplied.  '
		break
	fi

	# search download using entered id
	echo "searching, please wait" 
	result=$(grep -n "${id}" "$csv")
	if [ -z "$result" ]
	then	echo 'No match found!'
		sleep 2
		continue
	fi
	printf 'match found in line %s\n' "$result"
	printf '%s & %s\n' "$id" "$result" >> "$logf"
	# sleep 2 # Do you want to sleep here too?
done
echo 'Leaving match function.'
sleep 2
exit

BASHBUG(1)						      General Commands Manual							BASHBUG(1)

NAME

       bashbug - report a bug in bash

SYNOPSIS

       bashbug [--version] [--help] [email-address]

DESCRIPTION

       bashbug	is  a shell script to help the user compose and mail bug reports concerning bash in a standard format.	bashbug invokes the editor
       specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill  in  the  appropriate
       fields  and  exit  the  editor.	 bashbug  then	mails the completed report to bug-bash@gnu.org, or email-address.  If the report cannot be
       mailed, it is saved in the file dead.bashbug in the invoking user's home directory.

       The bug report format outline consists of several sections.  The first section provides information about the  machine,	operating  system,
       the  bash  version, and the compilation environment.  The second section should be filled in with a description of the bug.  The third sec-
       tion should be a description of how to reproduce the bug.  The optional fourth section is for a proposed fix.  Fixes are encouraged.

ENVIRONMENT

       bashbug will utilize the following environment variables if they exist:

       EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.

       HOME   Directory in which the failed bug report is saved if the mail fails.

       TMPDIR Directory in which to create temporary files and directories.
