Synchronize directory contents by copying outdated or missing files.

GONC

gonc is a small tool written originally to synchronize gopher log (phlog) files and directories.

It simply copies files from the source directory that are either outdated or not present in the destination directory. It can also delete those files at the destination that have been deleted at source.

Why?

My phlog is hosted on a system where I do not have access to rsync. The phlog is under version control, so I needed to copy the contents of the working directory to the directory that is served by the gopher server. Without rsync and gonc I just used cp -a.

Compile

gonc is a single C file, so make can be used even without a makefile to compile it:

make gonc

To explicitly specify the compiler, just set CC:

CC=gcc make gonc

gonc depends on fts that is not included in musl. See the Dockerfile for how to compile using clang and musl.

Use

Usage:
        gonc [-d] [-n] source_dir destination_dir
        gonc -h
        gonc -v

Options:
        -d      Delete files at destination that are not in source.
        -n      Dry run. No files will be copied or deleted.
        -h      Show this help.
        -v      Show the version number.
