Question

How to convert array elements with single quotes and comma in Bash.

arr=("element1" "element2" "element3")
#element1 element2 element3

Desired result 'element1','element2','element3'

From Martin Clayton answer comma seprated values are achieved using IFS,

SAVE_IFS="$IFS"
IFS=","
ARRJOIN="${arr[*]}"
IFS="$SAVE_IFS"

echo "$ARRJOIN"
#element1,element2,element3
