Combining lines of files to new file

Hi everybody.
I have a number of files that i would like to combine. however not concatenating, but rather extract lines from the files.
Example:

File1 ------ File2 ------File3 ...
line11 ---- line21 ---- line31 ...
line12 ---- line22 ---- line32 ...
line13 ---- line23 ---- line33 ...
... ...

and i want to have something like
File1 ----- File2 ------ File3
line11 ---- line12 ---- line13
line21 ---- line22 ---- line23
line31 ---- line32 ---- line33

That means a file containing all the first lines, one for the 2nd lines, one for the 3rd, and so on. Is there an easy way to do this?
Appreciate any help.

NAME
paste - paste multiple files together SYNOPSIS
paste [-s] [-d list] file... OPTIONS
-d Set delimiter used to separate columns to list. -s Print files sequentially, file k on line k. EXAMPLES
paste file1 file2 # Print file1 in col 1, file2 in col 2 paste -s f1 f2 # Print f1 on line 1 and f2 on line 2 paste -d : file1 file2 # Print the lines separated by a colon DESCRIPTION
Paste concatenates corresponding lines of the given input files and writes them to standard output. The lines of the different files are separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except the last one. If end-of-file is hit on an input file, subsequent lines are empty. Suppose a set of k files each has one word per line. Then the paste output will have k columns, with the contents of file j in column j. If the -s flag is given, then the first file is on line 1, the second file on line 2, etc. In effect, -s turns the output sideways. If a list of delimiters is given, they are used in turn. The C escape sequences , , \, and are used for linefeed, tab, backslash, and the null string, respectively. PASTE(1)
