ftwin - find duplicate files

SYNOPSIS

ftwin [OPTION]... [FILES OR DIRECTORIES]...

DESCRIPTION

ftwin reports two files if they are duplicates from each other.

Mandatory arguments to long options are mandatory for short options too.

-c, --case-unsensitive: this option applies to regex match, -e or -w.
-d, --display-size: display size before duplicates.
-e, --regex-ignore-file REGEX: filenames that match this are ignored.
-f, --follow-symlink: follow symbolic links.
-h, --help: display usage informations.
-I, --image-cmp: will run ftwin in image cmp mode (using libpuzzle).
-T, --image-threshold: will change the image similarity threshold (default is [1], accepted [2/3/4/5]). [1] will display only very similar pictures, [5] will be the most permissive.
-i, --ignore-list file1,file2,...,filen: comma-separated list of file names to ignore.
-m, --minimal-length size in bytes: minimum size of file to process.
-o, --optimize-memory: reduce memory usage, but increase process time. (This option is not implemented yet)
-p, --priority-path path: file in this path are displayed first when duplicates are reported.
-r, --recurse-subdir: recurse subdirectories.
-s, --separator character: separator character between twins, default: \n.
-t, --tar-cmp: will process files archived in .tar(.gz) default: off.
-v, --verbose: display a progress indicator.
-V, --version: display version.
-w, --whitelist-regex-file REGEX: filenames that doesn't match this are ignored.
-x, --excessive-size size in bytes: files that exceed this limit won't be read using mmap.

EXAMPLES

The following command line will report duplicate pictures, using libpuzzle (-I) whose sizes are greater than 8192 bytes ( -m 8192 ) found recursively (-r) starting in your home directory.

$ ftwin -m 8192 -v -r -I ${HOME}

This line will report duplicate files (no more in "image mode", but according to their content) whose extension is .txt and that are not in a .svn directory:

$ ftwin -e ".*/\.svn/.*" -w ".*\.txt$" -v -r ${HOME}
