I am asking this because the file I have doesn't always follow a pattern.
For example the file I have is the result of a command to obtain windows ACLs:
icacls C:\ /t >output.txt


The order, number of lines that start with whitespace but have some text will change.
Code:
t e s t string 1 2 3 4 5
        sample a b c d e
        othersample 1 2 3 4 5

Should say

t e s t string 1 2 3 4 5
t e s t sample a b c d e
t e s t othersample 1 2 3 4 5

Another example: 
text 1 string 9 7 8 6
       something x \ / x
       something else 1 1 1 1 1 1 1 1

Same as before
text 1 string 9 7 8 6
text 1 something x \ / x
text 1 something else 1 1 1 1 1 1 1 1

I don't get it, why shouldn't the output be:

Code:
t e s t string 1 2 3 4 5
t e s t sample a b c d e
t e s t othersamplec1d2e3 4 5

and:
Code:
text 1 string 9 7 8 6
text 1 something7x8\6/ x
text 1 something7else/1x1 1 1 1 1 1 1

You say "whitespace". Are there tabs in the input you're processing or just spaces? If there are tabs, are they to be treated as a single whitespace character, or are they to be treated as one to eight space characters (assuming tab stops are set on every 8th position) depending on where they are located on an input line?

What operating system and shell are you using?

What have you tried to solve this problem on your own?
