Split String into array in Linux

Question

I have the following variable IP_LIST

The command echo $IP_LIST gives the result

"10.36.107.121" "10.45.167.243" "10.12.154.43"`

I am trying to store the result into an array using the command

myarray=(`echo $IP_LIST | tr ' ' ' '`)

But on the command echo $myarray I am getting the result

"10.36.107.121"

Whats the possible error

Whats the possible error There's no error and everything is working as it should. Did you expect something different to be printed out? ` This tells me that tr is used to split strings –` No, that is not what is says. On that site tr is used to replace , with a space. There's no point in changing space into a space... tr ' ' ' ' is useless. Just myarray=($IP_LIST) — KamilCuk

echo "${myarray[@]}" will print out the full array, instead of only the first element. You build the array correctly, but the echo statement was wrong.
