Yes, it is incompatible with other shells (sh/ksh/bash ...), and one of the most significant incompatibilities. See 'man zshexpn' and search for SH_WORD_SPLIT. > It should print: > "item1" > "item2" > "item3" You can get this by: [1] use array (instead of scalar parameter items) a=( item1 item2 item3 ) for i in $a; do ... done [2] use ${=items} for i in ${=items}; do ... done [3] set SH_WORD_SPLIT option setopt SH_WORD_SPLIT for i in $items; do ... done I prefer [1], but it is up to you which method you use.
