Hi again 
Is there any way to format a string. I.E. I've got a variable which may
be 1, 2, 3 and the variable is added to string. I want to show whole
string formatted as follows:
100
1
10
1100
not like that:
100
1
10
1100
Any help would be helpful (as always 
)
thanks in advance

Please look for printf, sprintf and % in the docs. The last one might
be hard to find. You use it as: "%3d" % 1
Kind regards

it would be nice to show original string and it's transformation,
but anyway, is it like this?
irb(main):092:0> "1 20 333 1000 55".split.each{|x| puts x.rjust(4)}
1
20
333
1000
55
this is just using #rjust.
irb(main):093:0> system "qri String#rjust"
----------------------------------------------------------- String#rjust
str.rjust(integer, padstr=' ') => new_str
From: Marcin Tyman [mailto:m.tyman@interia.pl]
------------------------------------------------------------------------
If integer is greater than the length of str, returns a new String
of length integer with str right justified and padded with padstr;
otherwise, returns str.
"hello".rjust(4) #=> "hello"
"hello".rjust(20) #=> " hello"
"hello".rjust(20, '1234') #=> "123412341234123hello"
=> true

robert already gave a handful of other hints.

OK, Fine. But... I want to format the string not its output to redirect
the string to a file on remote machine (the file should be formatted).

sprintf and % return a string, they don't print anything to the screen. You
can write the result of "%3d" % 1 to a file without a problem.

Now what? Do you want to output or not? I do not understand your
remark because with the methods I listed you can do output as well as
change strings.

the simple way is just do the output on screen (in a format you want). then if you're happy with the output, just redirect it to a file.
like eg,
ruby mytestprogram.rb > myfile
just try it.

Same is true for rjust() : http://www.whytheluckystiff.net/ruby/pickaxe/html/ref_c_string.html#String.rjust
