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

To remove any trailing carriage returns from each array element, try

outputArray=( "${outputArray[@]%$'\r'}" )

However, it would probably be better to examine how outputArray is set in the first place and prevent the carriage returns from being added in the first place. If you are reading from a file that uses DOS line endings, try "cleaning" it first using dos2unix.
