removing the duplicate lines in a file

Hi,

I need to concatenate three files in to one destination file.In this if some duplicate data occurs it should be deleted.
eg:
file1:
-----
data1 value1
data2 value2
data3 value3

file2:
-----
data1 value1
data4 value4
data5 value5

file3:
-----
data1 value1
data4 value4
data3 value3
data6 value6

the result file:
--------------
data1 value1
data2 value2
data3 value3
data4 value4
data5 value5
data6 value6

How to achieve this?

NAME
fntsample - PDF and PostScript font samples generator SYNOPSIS
fntsample [ OPTIONS ] -f FONT-FILE -o OUTPUT-FILE fntsample -h DESCRIPTION
fntsample program can be used to generate font samples that show Unicode coverage of the font and are similar in appearance to Unicode charts. Samples can be saved into PDF (default) or PostScript file. OPTIONS
fntsample supports the following options. --font-file, -f FONT-FILE Make samples of FONT-FILE. --font-index, -n IDX Font index for FONT-FILE specified using --font-file option. Useful for files that contain multiple fonts, like TrueType Collec- tions (.ttc). By default font with index 0 is used. --output-file, -o OUTPUT-FILE Write output to OUTPUT-FILE. --other-font-file, -d OTHER-FONT Compare FONT-FILE with OTHER-FONT. Glyphs added to FONT-FILE will be highlighted. --other-index, -m IDX Font index for OTHER-FONT specified using --other-font-file option. --postscript-output, -s Use PostScript format for output instead of PDF. --svg, -g Use SVG format for output. The generated document contains one page. Use range selection options to specify which. --print-outline, -l Print document outlines data to standard output. This data can be used to add outlines (aka bookmarks) to resulting PDF file with pdfoutline program. --include-range, -i RANGE Show characters in RANGE. --exclude-range, -x RANGE Do not show characters in RANGE. --style, -t "STYLE: VAL" Set STYLE to value VAL. Run fntsample with option --help to see list of styles and default values. --help, -h Display help text and exit. Parameter RANGE for -i and -x can be given as one integer or a pair of integers delimited by minus sign (-). Integers can be specified in decimal, hexadecimal (0x...) or octal (0...) format. One integer of a pair can be missing (-N can be used to specify all characters with codes less or equal to N, and N- for all characters with codes greather or equal to N). Multiple -i and -x options can be used. EXAMPLES
Make PDF samples for font.ttf and write them to file samples.pdf: fntsample -f font.ttf -o samples.pdf Make PDF samples for font.ttf, compare it with oldfont.ttf and highlight new glyphs. Write output to file samples.pdf: fntsample -f font.ttf -d oldfont.ttf -o samples.pdf Make PostScript samples for font.ttf and write output to file samples.ps. Show only glyphs for characters with codes less or equal to U+04FF but exclude U+0370-U+03FF: fntsample -f font.ttf -s -o samples.ps -i -0x04FF -x 0x0370-0x03FF Make PDF samples for font.ttf and save output to file samples.pdf adding outlines to it: fntsample -f font.ttf -o temp.pdf -l > outlines.txt pdfoutline temp.pdf outlines.txt samples.pdf AUTHOR
