How to get first string from a bash list? -

-

i have bash list (space separated string) , want extract first string it.

example: 

 var="aaa bbb ccc" -> need "aaa"  var="xxx" -> need "xxx"

is there other trick using break ?

try format:

echo "${var%% *}"

another way is:

read first __ <<< "$var" echo "$first"
