linux - while read bash array (not into) -

-

i'm trying use array while read, entire array output @ once.

#!/bin/bash  declare -a arr=('1:one' '2:two' '3:three');  while read -e ;     echo $it done <<< ${arr[@]}

it should output each value separately (but doesn't), maybe while read isn't hot ticket here?

for case, easier use for loop:

$ declare -a arr=('1:one' '2:two' '3:three') $ in "${arr[@]}"; echo $it; done 1:one 2:two 3:three

the while read approach useful (a) when want read data file, , (b) when want read in nul or newline separated string. in case, however, have data in bash variable , for loop simpler.
