About par2cmdline

par2cmdline creates PAR2 parity data for a set of files and later uses it to verify them and reconstruct parts that are damaged or missing. It is the official implementation from the Parchive project and also provides libpar2.

It suits Usenet users, people archiving data to unreliable media and anyone who wants to script integrity checks. Build files are included for Unix-like systems and Visual Studio on Windows.

Strengths

  • Official reference implementation of PAR2
  • Verifies and repairs damaged or missing files
  • Easy to use in scripts

Limitations

  • Command-line only
  • Recovery depends on how much parity data was created
