File duplicates

A simple util for searching for file duplicates in folders. File duplicates can be search by:

• comparing files by a calculated hash of a file's content;
• by comparing files' names, content is ignored.

An util performs search in specified folders. A user can specify from 1 to N folders to be searched in. Multiple folders are separated by colon when specified, for example:

fdups -f /test:/content:/tmp:/logs

Sample help output:

Usage:
  fdups [OPTION...]

  -h, --help              Print usage
  -f, --folders arg       folders where to look for duplicates; specify 
                          folders in format f1[:f2[:f3[:fn]]]; path of 
                          execution is used is used by default
  -m, --compare-mode arg  supports comparing by "hash" or by "name". "hash" 
                          is used by default
  -p, --pattern arg       regex for a file name, ".*" is used by default

Utility prints list of file duplicates to a standard output. Sample output:

user@machine:/$ fdups -p .\* -m hash -f /test

Performing search by following arguments:
> folders: 
/test
> comparing method: hash
> pattern: .*
