I was looking through bash commands that codecaine posted and i came on to this one.
I though that it would be good to make it.
I know that Delphi has similar function that only trims spaces " ".
It has trim(), trimleft() and trimright() functions.
Here is the example :

Code:

var

string mystring;

begin

mystring = '  Text     ';

showmessage('[' + trimleft(mystring)  + ']');

showmessage('[' + trimright(mystring) + ']');

showmessage('[' + trim(mystring)      + ']');

end;

And the output should be :

Code:

[Text     ]

   [  Text]

   [Text]
