nixpkgs / flockit - This library and tool exists solely because rsync doesn't have file locking. It's not used like a normal library; you don't link against it, and you don't have to patch your source code to use it. It's inserted between your program and its libraries by use of LD_PRELOAD. For example: $ env LD_PRELOAD=$(nix-build -A pkgs.flockit)/lib/ FLOCKIT_FILE_PREFIX=test rsync SRC DEST Besides the library a handy executable is provided which can simplify the above to: $ $(nix-build -A pkgs.flockit)/bin/flockit test rsync SRC DEST Also see the following blog post:
