lzw3 0.4

REQUIREMENTS

Requires at least Python 3.5.

INSTALLATION

pip install lzw3

USAGE

Two scripts will be installed in your local binary path (e.g. /home/user/.local/bin): compress and uncompress. If you want to invoke these scripts, ensure that your $PATH contains the python binary path Note that this compressor just compress regular files (i.e. doesn’t create an archive such as .zip or .tar.gz). Anyhow, directory can still be compressed using the option: -r

python3 -m lzw3.compressor doc1.txt doc2.txt

python3 -m lzw3.compressor -r /home/user/Docs/Project

compress doc1.txt doc2.txt

-r
    Recursively compress the files inside the directories
    within the given file list.
    If not specified, directories in the file list are skipped.

-v
    Prints information about the handled files and the percentage of
    saved space for each compressed file.

-t
    Prints the time spent for compress each file.

-k
    Keeps the original files instead of replace those with the
    compressed ones.

-f
    Force to compress and keep the compressed file, even if the size
    of the compressed file is higher than the size of the original one.

-d
    Prints debug messages.

python3 -m lzw3.decompressor doc1.txt.Z doc2.txt.Z

python3 -m lzw3.decompressor -r /home/user/Docs/Project

uncompress doc1.txt.Z doc2.txt.Z

-r
    Recursively decompress the files inside the directories
