Prevent / Avoid ^M in linux/unix script

i have script like this below : testing.sh

#!/bin/bash

while read inputline
do
        plugin="$(echo $inputline | cut -d, -f 3-)"

        echo \"$plugin\" > test1.out
done < $1

exit 0

config file : test.conf

host1-192.168.31.200,Current_Users,check_users -w 20 -c 50

after execute the script :

#./testing.sh test.conf

the output file : test1.out

"check_users -w 20 -c 50^M"

The easiest way is probably to edit your test.conf file to remove it (did it come from another OS?). However, you can also use tr to get rid of it:

plugin="$(echo $inputline | tr -d \\r | cut -d, -f 3-)"
