find, if exists then append for file with same name

I will have to process multiple files with same name [filename.txt] everyday.
My requirement is:
If on a certain day I see that filename.txt exists then the contents of the filename.txt would be added/append
to the former file contents.Each time it sees the file the content would be added.But the header
should not be added
For ex: There exists this file
filename.txt
First Name|Second Name
John|Marshall

Next time I get the same file
filename.txt
First Name|Second Name
Jack|Dowell

I need the next file to become like
filename.txt
First Name|Second Name
John|Marshall
Jack|Dowell
Can you please suggest something? Thanks in advance.

uuencode(n)						   encode/decoding a binary file					       uuencode(n)

NAME
uuencode - encode/decoding a binary file SYNOPSIS
package require Tcl 8 package require uuencode ?1.0.1? ::uuencode::encode string ::uuencode::decode string ::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string) ::uuencode::uudecode (-file filename | ?--? string) DESCRIPTION
This package provides a Tcl-only implementation of the uuencode(1) and uudecode(1) commands. This encoding packs binary data into printable ASCII characters. ::uuencode::encode string returns the uuencoded data. This will encode all the data passed in even if this is longer than the uuencode maximum line length. If the number of input bytes is not a multiple of 3 then additional 0 bytes are added to pad the string. ::uuencode::decode string Decodes the given encoded data. This will return any padding characters as well and it is the callers responsibility to deal with handling the actual length of the encoded data. (see uuencode). ::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string) ::uuencode::uudecode (-file filename | ?--? string) UUDecode a file or block of data. A file may contain more than one embedded file so the result is a list where each element is a three element list of filename, mode value and data. OPTIONS
-filename name Cause the uuencode or uudecode commands to read their data from the named file rather that taking a string parameter. -name string The uuencoded data header line contains the suggested file name to be used when unpacking the data. Use this option to change this from the default of "data.dat". -mode octal The uuencoded data header line contains a suggested permissions bit pattern expressed as an octal string. To change the default of 0644 you can set this option. For instance, 0755 would be suitable for an executable. See chmod(1). EXAMPLES
% set d [uuencode::encode "Hello World!"] 2&5L;&@5V]R;&0A % uuencode::uudecode $d Hello World! % set d [uuencode::uuencode -name hello.txt "Hello World"] begin 644 hello.txt +2&5L;&@5V]R;&0` ` end % uuencode::uudecode $d {hello.txt 644 {Hello World}} KEYWORDS
