Using Command Line Tool

In addition to the GUI application, SyncBreeze Pro includes a command line tool allowing one to execute file synchronization commands from an OS shell window. The SyncBreeze command line tool provides power users and system administrators with the ability to integrate file synchronization capabilities into batch files and shell scripts. The SyncBreeze command line tool is located in <ProductDir>/bin directory.

Command Line Syntax:

syncbreeze -execute <Sync Command Name>

Executes the specified file synchronization command.

syncbreeze -sync -source <SourceDirectory> -dest <DestDirectory>

Synchronizes files between directories, local disks or network shares.

Parameters:

-source <Source Directory>

This parameter specifies the source directory for file synchronization. In order to ensure proper parsing of command line arguments, directories containing space characters should be double quoted.

-dest <Destination Directory>

This parameter specifies the destination directory for file synchronization. In order to ensure proper parsing of command line arguments, directories containing space characters should be double quoted.

Options:

-mode <SD | SUD | SAD | STW | STA>

SD - Sets the sync-destination file synchronization mode (Default)

All changes made in the source directory will be propagated to destination. Files deleted from the source directory will be deleted from destination. All files changed or deleted in destination will be restored from source.

Newly created and modified source files will be copied to destination. Files deleted from the source directory will be deleted from destination. Files deleted from the destination directory will be restored from source.
