Pre Command and Post Command Scripts - gilbertchen/duplicacy GitHub Wiki

You can instruct Duplicacy to run a script before or after executing a command.

For example, if you create a bash script with the name pre-prune under the .duplicacy/scripts directory, this bash script will be run before the prune command starts. A script named post-prune will be run after the prune command finishes.

This rule applies to all commands except init.

On Windows these scripts should have the .bat extension in their names, while on linux they should have no extension.
