[Help-bash] How to set IFS temporarily? (along with assignment and array initiation)

[Peng Yu]

Hi,

I use the following 4 lines to set IFS temporarily. But it uses a
temporary variable OLD_IFS, which could be used by other accidentally.
Therefore, this piece of code is not entirely safe.

Does anybody have any better solution that this? Thanks.

~~~
OLD_IFS="$IFS"
IFS=$'\n'
array=($(printf "%s\n" 'a b' 'c d'))
IFS="$OLD_IFS"

printf "%s\n" "address@hidden"
~~~
