This program manages files and directories on Linux systems, allowing users to create hardlinks between files. It provides the ability to detect missing files based on their inode number across multiple directories. The application can be used in both simulation mode and real execution mode.

The program requires Go to be installed on your system. If you don't have it yet, please install it first by following the official instructions at Go website. Once installed, clone this repository using Git:

git clone https://github.com/sunrize/d2dhl.git
cd d2dhl

Then, build the binary:

go build

After building, you will find the executable file d2dhl in the root directory of the project.

To use the program, specify the required arguments as follows:

./d2dhl -src_dirs="path/to/source1,path/to/source2" -dst_dirs="path/to/destination1,path/to/destination2" -dest="path/to/main/destination"

Here are some usage examples:

1. Detect missing files and create hard links without console output:

   ./d2dhl -src_dirs="path/to/source1,path/to/source2" -dst_dirs="path/to/destination1,path/to/destination2" -dest="path/to/main/destination"

2. Detect missing files and create hard links with console output:

   ./d2dhl -src_dirs="path/to/source1,path/to/source2" -dst_dirs="path/to/destination1,path/to/destination2" -dest="path/to/main/destination" -output

3. Dry run to see what would happen without performing any action:

   ./d2dhl -src_dirs="path/to/source1,path/to/source2" -dst_dirs="path/to/destination1,path/to/destination2" -dest="path/to/main/destination" -dry

Each parameter must be separated by commas.
