echo read bash read array

This is how you should push a string in a command's stdin.

Don't do this: echo word | command Using a bash "here strings" and "here documents" look leeter than piping echo into the command. Also prevents subshell execution. Word is also expanded as usual.
This is sample output - yours may be different.

What Others Think

Good one ! it works with a variable within double quotes like : V='world domination now!' read -a ARR <<<"$V"; echo ${ARR[2]}; And the separator can be changed (to ':') this way: IFS=':' read -a ARR <<<"$V"; echo ${ARR[2]};
