I've searched about a bit and more than likely, I'm not entering the correct search phrase, but my question is as follows:
When a user does an 'ls' (and whatever various flags needed) and in the results, we see duplicate or backup files from editing. IE:

Hi!
I want to find duplicate files (criteria: file size) in my download folder.
I try it like this:
find /Users/frodo/Downloads \! -type d -exec du {} \; | sort > /Users/frodo/Desktop/duplicates_1.txt;

Hi champs,
I have one of the requirement, where I need to compare two files line by line and ignore duplicates. Note, I hav files in sorted order.
I have tried using the comm command, but its not working for my scenario.

I am so frustrated!!!
I want a nice command that clears away duplicate files:
find . -type f -regex '.*{1,3}\..*' | xargs -I## rm -v '##'
should work in my opinion. But it finds nothing even though I have files that have the file name:

cksum
cksum(3tcl) Cyclic Redundancy Checks cksum(3tcl)__________________________________________________________________________________________________________________________________________________NAME
cksum - Calculate a cksum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2
package require cksum ?1.1.3?
::crc::cksum ?-format format? ?-chunksize size? [ -channel chan | -filename file | string ]
::crc::CksumInit
::crc::CksumUpdate token data
::crc::CksumFinal token
_________________________________________________________________DESCRIPTION
This package provides a Tcl implementation of the cksum(1) algorithm based upon information provided at in the GNU implementation of this
program as part of the GNU Textutils 2.0 package.
COMMANDS
::crc::cksum ?-format format? ?-chunksize size? [ -channel chan | -filename file | string ]
The command takes string data or a channel or file name and returns a checksum value calculated using the cksum(1) algorithm. The
result is formatted using the format(3tcl) specifier provided or as an unsigned integer (%u) by default.
OPTIONS -channel name
Return a checksum for the data read from a channel. The command will read data from the channel until the eof is true. If you need
to be able to process events during this calculation see the PROGRAMMING INTERFACE section
-filename name
This is a convenience option that opens the specified file, sets the encoding to binary and then acts as if the -channel option had
been used. The file is closed on completion.
-format string
Return the checksum using an alternative format template.
PROGRAMMING INTERFACE
The cksum package implements the checksum using a context variable to which additional data can be added at any time. This is expecially
useful in an event based environment such as a Tk application or a web server package. Data to be checksummed may be handled incrementally
during a fileevent handler in discrete chunks. This can improve the interactive nature of a GUI application and can help to avoid excessive
memory consumption.
::crc::CksumInit
Begins a new cksum context. Returns a token ID that must be used for the remaining functions. An optional seed may be specified if
required.
::crc::CksumUpdate token data
Add data to the checksum identified by token. Calling CksumUpdate $token "abcd" is equivalent to calling CksumUpdate $token "ab"
followed by CksumUpdate $token "cb". See EXAMPLES.
::crc::CksumFinal token
Returns the checksum value and releases any resources held by this token. Once this command completes the token will be invalid. The
result is a 32 bit integer value.
EXAMPLES
% crc::cksum "Hello, World!"
2609532967
% crc::cksum -format 0x%X "Hello, World!"
0x9B8A5027
% crc::cksum -file cksum.tcl
1828321145
% set tok [crc::CksumInit]
% crc::CksumUpdate $tok "Hello, "
% crc::CksumUpdate $tok "World!"
% crc::CksumFinal $tok
