Bash script array to csv

Question

I want to do comma separated string from my array. In my script i collecting data to array outputArr and then i want to echo it to check it out, but no

Answer 1

Your array contains elements with carriage returns:

$ foo=($'\rterminally yours' $'\r2204')
$ echo "${foo[0]}"
terminally yours
$ echo "${foo[1]}"
2204
$ echo "${foo[*]}"
2204inally yours 

For your code, you can add the following to remove the carriage return from the variable:

singleLine=${singleLine//$'\r'/}
