Version of JDK’s `jar’ command written entirely in C

Fastjar is a version of Sun’s jar' utility, written entirely in C, and therefore quite a bit faster. Fastjar can be up to 100x faster than the stock jar’ program running without a JIT. Currently, the author is working on adding all the features present in the Sun utility. At the moment, implemented features are

  • Archive creation
  • Verbose/quiet output
  • stdout vs. file output
  • Manifest file support
  • Deflation or storage
  • Changing to directory and adding files -C
  • Archive content listing -t
  • Archive extraction -x
