Report Location:

Generate custom report path using -r or --report=/tmp/report.txt::

./liten.py --report=/tmp/test.txt /Users/ngift/Documents

By default a report will be created in CWD, called LitenDuplicateReport.csv

Config File:

You can use a config file in the following format::

    [Options]
    path=/tmp
    size=1MB
    pattern=*.m4v
    delete=True

You can call the config file anything and place it anywhere.

Here is an example usage::

./liten.py --config=myconfig.ini

Verbosity:

All stdout can be suppressed by using --quiet or -q.

Delete:

By using --delete the duplicate files will be automatically deleted. The API has support for an interactive mode and a dry-run mode, they have not been implemented in the CLI as of yet.

Example Library/API Usage:

    >>> Liten = Liten(spath='testData')
    >>> dupeFileOne = 'testData/testDocOne.txt'
    >>> checksumOne = Liten.createChecksum(dupeFileOne)
    >>> dupeFileTwo = 'testData/testDocTwo.txt'
    >>> checksumTwo = Liten.createChecksum(dupeFileTwo)
    >>> nonDupeFile = 'testData/testDocThree_wrong_match.txt'
    >>> checksumThree = Liten.createChecksum(nonDupeFile)
    >>> checksumOne == checksumTwo
    True
    >>> checksumOne == checksumThree
    False

There is also the concept of an Action, which can be implemented later, that will allow customizable actions to occur upon an a condition that gets defined as you walk down a tree of files.

Tests:

Run Doctests: ./liten -t or --test
Run test_liten.py
Run test_create_file.py then delete those test files using liten::

python2.5 liten.py --delete /tmp

Display Options:

Stdout:

stdout will show you duplicate file paths and sizes such as::

    Printing dups over 1 MB using md5 checksum: [SIZE] [ORIG] [DUP]
    7 MB  Orig:  /Users/ngift/Downloads/bzr-0-2.17.tar
    Dupe:  /Users/ngift/Downloads/bzr-0-4.17.tar

Report:

A report named LitenDuplicateReport.csv will be created in your current working directory::

    Duplicate Version,     Path,       Size,       ModDate
    Original, /Users/ngift/Downloads/bzr-0-2.17.tar, 7 MB, 07/10/2007 01:43:12 AM
    Duplicate, /Users/ngift/Downloads/bzr-0-3.17.tar, 7 MB, 07/10/2007 01:43:27 AM

Debug Mode Environmental Variables:

To enable print statement debugging set LITEN_DEBUG to 1

To enable pdb break point debugging set LITEN_DEBUG to 2

LITEN_DEBUG_MODE = int(os.environ.get('LITEN_DEBUG', 0))

Note: When DEBUG MODE is enabled, a message will appear to standard out
