mmd5sum: calculate multiple MD5s using multiple processing

If you have a huge many files that want to calculate MD5, you will need mmd5sum. mmd5sum calculate a directory of files (can have sub-directories) using multiple processes.

installation

pip install mmd5sum

features

1. can specify a directory (can have sub-directories)
2. can read calculated results to avoid recalculating
3. can specify how many processes to use
4. default using local machine command md5sum, but can specify another one

usage

mmd5sum -d /path/to/directory -o md5.txt

If you have a file that some file already calculated:

mmd5sum -d /path/to/to/directory -i old_md5.txt -o new_md5.txt

If you want faster:

mmd5sum -d /path/to/directory -o md5.txt -p 10

-p 10 means you will have 10 processes in parallel, default is 4.

mmd5sum default use md5sum command to calculate MD5, if the command calculate MD5 on you machine isn't md5sum:

mmd5sum -d /path/to/directory -o md5.txt -m md5

-m md5 means the command on your machine is md5。
