Installing fdupes -------------------------------------------------------------------- You're looking at a DEVELOPMENT version of fdupes. If you're not a software developer or you just want to install the program, this is probably not the version you want. This version of fdupes is currently in development and subject to change. The features and functionality present in this version may not reflect the features and functionality in the final release. The easiest way to install fdupes is to use your operating system's package manager, if available. If that's not an option or you'd prefer to compile the program yourself (which may sometimes be the only way to obtain the latest version), you should download a RELEASE version of fdupes and follow the installation instructions provided with it. As of this writing, fdupes releases may be downloaded from: https://github.com/adrianlopezroche/fdupes/releases If you're a programmer and you wish to use or work on this version of fdupes you will need to install autoconf and automake on your system and run autoreconf --install to generate the configure script and other files needed for compilation and installation. After that you may compile fdupes by running: ./configure make and install it by running: sudo make install
