Sync Version 1 descriptions Sync is a simple command-line utility for performing one-way directory or file synchronization. It synchronizes the specified target to match the specified source. Only the target is modified. Runs on any OS with the Java Runtime Environment . Sync is free & open source software written in Java & released under the GNU GPL license . MAIN FEATURES: * FLEXIBLE FILE-MATCHING: Match files by combinations of name size last-modified time & CRC-32 checksum by default are used. * FLEXIBLE FILE TIME COMPARISON: Specify a time-tolerance when matching files by their last-modified time. * FILENAME FILTER: Use a GLOB or REGEX filter for file/directory names or their full pathnames. * SIMULATION MODE: Sync can be run to simulate file operations so that the target directory is not modified. * UNATTENDED USAGE: With an appropriate choice of switches Sync can be executed without user intervention.
