FastDup 0.3 (Default branch)
FastDup is a tool to find identical files withindirectory trees, with a focus on the ability toscan very large trees and files in reasonableamounts of time. The use of clever techniques andoptimizations to avoid comparisons allows fastdupto significantly outperform many existingsolutions, and has a benefit of being entirely I/Obound (insignificant CPU usage). It is releasedunder a modified BSD license, allowing all use,redistribution, and modification fornon-commercial purposes.License: GNU General Public License (GPL)Changes:
This release adds a progress display while comparing files and an option to filter the files included in scanning by file size. Several minor bugs have been resolved, including a compilation error on GCC 4.3 and several minor memory leaks. The license has been changed to the GPLv3.Image

cp

CP(1)							      General Commands Manual							     CP(1)

NAME

       cp, cpdir - file copy

SYNOPSIS

       cp [-pifsmrRvx] file1 file2
       cp [-pifsrRvx] file ... directory
       cpdir [-ifvx] file1 file2

OPTIONS

       -p     Preserve full mode, uid, gid and times

       -i     Ask before removing existing file

       -f     Forced remove existing file

       -s     Make similar, copy some attributes

       -m     Merge trees, disable the into-a-directory trick

       -r     Copy directory trees with link structure, etc. intact

       -R     Copy directory trees and treat special files as ordinary

       -v     Display what cp is doing

       -x     Do not cross device boundaries

EXAMPLES

       cp oldfile newfile  # Copy oldfile to newfile

       cp -R dir1 dir2	   # Copy a directory tree

DESCRIPTION

       Cp  copies one file to another, or copies one or more files to a directory.  Special files are normally opened and read, unless -r is used.
       -r also copies the link structure, something -R doesn't care about.  The -s option differs from -p that it only copies  the  times  if  the
       target file already exists.  A normal copy only copies the mode of the file, with the file creation mask applied.  Set-uid bits are cleared
       if the owner cannot be set.  (The -s flag does not patronize you by clearing bits.  Alas -s and -r are nonstandard.)

       Cpdir is a convenient synonym for cp -psmr to make a precise copy of a directory tree.
