This tool allows to recursively compress an archive relying on Patool, a Python
library supporting various archive formats.
Note: Password-protected compression is not supported.
positional arguments:
files files to be archived
optional arguments:
-c CHARSET character set of random archive name (default: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789)
-d delete input files (default: False)
-f FORMATS compression algorithms (default: all)
-n NCHARS length of random archive name (default: 8)
-r ROUNDS, --rounds ROUNDS
number of compression rounds (default: 10)
--reverse reverse byte order (default: False)
data options:
--data DATA data to be embedded (default: None)
--chunks CHUNKS number of chunks the data should be split in (default: 10)
extra arguments:
-h, --help show this help message and exit
-p, --progress progress mode (default: False)
-v, --verbose verbose mode (default: False)
timing arguments:
--stats display execution time stats at exit (default: False)
--timings display time stats during execution (default: False)
Usage examples:
rec-comp file1 file2 file3 -r 10
rec-comp file -c abcd -n 10
rec-comp -p
$ rec-comp file1 file2 file3 -r 10 -p

This tool allows to recursively decompress an archive relying on Patool, a
Python library supporting various archive formats.
Note: Password-protected compression is not supported yet. If the tool freezes
while decompressing, it may be necessary to press enter to submit a blank
password, which will stop decompression.
positional arguments:
archive input archive
optional arguments:
-d delete input archive (default: False)
-p print resulting file, if possible (default: False)
extra arguments:
-h, --help show this help message and exit
-v, --verbose verbose mode (default: False)
timing arguments:
--stats display execution time stats at exit (default: False)
--timings display time stats during execution (default: False)
Usage examples:
rec-decomp archive.zip
rec-decomp archive.zip -d
$ rec-decomp Vdpxp8Qy
