Accessing arrays position in a split string

Hi,

I've a string "this.is.a.name", and I would like to put it in an array.
But, I've like to print the output of the array as:

Code:

echo ${array[0]}

echo ${array[1]}

echo ${array[2]}

echo ${array[3]}

I've tried with

Code:

STR="this.is.a.name";

arr=$(echo $STR | tr "." " ");



echo ${array[0]}

echo ${array[1]}

echo ${array[2]}

echo ${array[3]}

but only the first position contains the phrase "this is a name". The rest of the array is empty.

I've searched over the manuals and the web, and I couldn't find a solution for my case.

How can I do that?

Thanks,

You're close, but you need to add another set of () when you assign the array.

Code:

#!/bin/bash

STR="this.is.a.name"

array=($(echo $STR | tr "." " "))

echo ${array[0]}

echo ${array[1]}

echo ${array[2]}

echo ${array[3]}

That's right Guttorm, but what's the meaning of the outer parenthesis of "($(echo $STR | tr "." " "))"?

Without the outer, the variable named array simply gets the value of "this is a name". The outer means it will be an array. The difference is the same as

array="this is a name"
array=(this is a name)

Now I get it. Thanks for the help.
