Store array output to comma separated list in bash scripting
If you have an array like this:
$ declare -p arrdeclare -a arr='([1]="abc" [2]="def")'You can display it in comma-separated format:
$ (IFS=,; echo "{${arr[*]}}"){abc,def}That output can be saved in a shell variable using command substitution:
$ var=$(IFS=,; echo "{${arr[*]}}")$ echo "$var"{abc,def}
