    Question Newbie ? : Sed vs Awk: Best Way To Filter a Pattern Match From String?

    I'm new to bash, and still uncertain when/how to use sed vs awk.

    I'm trying to assign all pattern matches in a string to a variable, and then filter them from a string.

    Here's the pattern:

    [space]*[space][space]* # 2 spaces and any character afterward until the next space.

    Or if at the start of string:
    *[space]

    Example:
    raw_string='test1 this is test2 string'

    I want: test1, test2 assigned to variables. And then filter the string to match, 'this is a string'.

    What is the right way to do this in bash?

    Thanks
