Quick overview

Usage

duplicacy cat [command options] [<file>]

Options


-id <snapshot id>

You can specify a different snapshot id rather than the default id.


-r <revision>

By default the latest revision is selected.
If -r is specified, then that revision is selected instead.


-storage <storage name>

You can use the -storage option to select a different storage other than the default one.


-key <private key> and -key-passphrase <passphrase>

If the storage is encrypted by an RSA public key, the corresponding private key is needed to print out the content of any file.

Notes

The file must be specified with a path relative to the repository.
