Convert a text string in bash to array

Another method using read:

read -a array <<< $str

In order to convert the string to an array, say:

$ str="title1 title2 title3 title4 title5"
$ arr=( $str )

The shell would perform word splitting on spaces unless you quote the string.

In order to loop over the elements in the thus created array:

$ for i in "${arr[@]}"; do echo $i; done
title1
title2
title3
title4
title5
