binleft

binleft is a command-line utility designed for efficient binary file synchronization. Its primary function is to copy files from a source directory to a destination directory, but with a focus on identifying and transferring only those files that are newer or different between the two locations. This makes it useful for tasks such as backing up modified files or updating development environments.

Unlike more basic copy commands, binleft analyzes the content or modification timestamps of files to determine if a transfer is necessary. This selective copying process can significantly reduce the time and bandwidth required for synchronization, especially when dealing with large datasets or frequent updates. The tool offers various options to control the synchronization behavior, including the ability to exclude specific files or directories, perform recursive copying, and handle symbolic links. It is often employed in scripting and automated workflows where maintaining consistent file sets is crucial. The utility is typically distributed as a standalone executable, making it relatively easy to integrate into existing systems.
