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.

Split() { eval "$1=( \"$(echo "${!1}" | sed "s/$2/\" \"/g")\" )"; }

Functions: eval

It works as a method applicated to a variable, converts the string variable into an array

Split() { SENT=${*} ; sentarry=( ${SENT} ) ; while [[ ${#sentarry[@]} -gt 0 ]] ; do printf "%s\n" "${sentarry[0]}" ; sentarry=( ${sentarry[@]:1} ) ; done ; }

Know a better way?

If you can do better, submit your command here.

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]};
