This question is similar to this one but it differs from it:
Consider this array with string elements which may contain spaces:
a@W:$ arr=("eins" "zwei" "eins plus zwei" "vier" "fünf")
a@W:$ echo ${#arr[@]} # ok, 5 elements, as expected
5
a@W:$ echo ${arr} # the fourth one, indexing starts at 0
vier
a@W:$ echo ${arr} # the third one, which contains two blancs
eins plus zwei
a@W:$ ar2=${arr[@]:0:3} # I only want the firs three of them
a@W:$ echo ${ar2[@]}
eins zwei eins plus zwei
a@W:$ echo ${#ar2[@]} # but they are all glued together into one element
1
a@W:$
**What mus I do to prevent this gluing them all together?** The string containing spaces, "eins plus zwei" shall stay the third element.
