Adding lines and columns to a file
Hi everybody,

I've got two simples file1 like:

Code:
aaa aaa aaa
bbb bbb bbb
ccc ccc ccc

and file2 like:
Code:
111 111 111
222 222 222
333 333 333

I need to:
1) add a line say "new line" as the first line of the file
2)add a column from file2 (say column3) to file1; the new column should be the new 4th column for example

I know this question has been asked before and I did find some solutions, but none of them are working for me.

This is what I've got so far:
1) add a new line code:
Code:
sed '1 i\new line' file1 > newfile

Problem: it adds "new line" after each line of my file1, when I need it to be one line only (the first one)

2) add a column code:
Code:
awk '{$4= " awk'{print $3}file2' "}1'

Problem: it also adds filed3 of file2 as the first column of every second line

Any ideas would be greately appretiated!

Many thanks in advance!!!

paste

PASTE(1)						      General Commands Manual							  PASTE(1)

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.
