yd-cli 0.7

CLI tool to synchronize directories using rsync.

Directory synchronization tool yd

Build and execute rsync commands from TOML configuration files.

Create a config

Create a new configuration called photos with:

yd edit --new photos

This command

• creates ~/.config/yd/photos.toml (or under $XDG_CONFIG_HOME/yd if set; relative paths are resolved from your home directory), and
• opens it in the editor selected via EDITOR.

Reopen an existing configuration with:

yd edit photos

Configuration format

Example

# Phone backup
src_home = "/home/alice"
target_home = "/mnt/backup"
backup = "deleted/%Y-%m-%d"
exclude = [".venv/", "__pycache__/"]

[[commands]]
src = "Documents"
exclude = ["*.log"]

[[commands]]
src = "Pictures"
target = "pics-%Y-%m-%d"
delete_extra = false

Leading comment lines directly at the top of the file are treated as the configuration description and are shown by yd ls.

Top-level options

Key	Meaning
src_home	Base directory for all src paths. Relative paths are resolved from your home directory.
target_home	Base directory for all target paths. Relative paths are resolved from your home directory. strftime placeholders such as %Y-%m-%d are supported.
mtp_target	Use in-place syncing for MTP targets.
backup	Backup directory for replaced or deleted files. Relative paths are resolved from target_home. strftime placeholders are supported.
exclude	Exclude patterns applied to every command.

mtp_target matters because rsync normally copies to a temporary file and renames it afterward, but that is not possible when syncing via MTP.

Command options

Key	Meaning
src	Relative source directory below src_home.
target	Relative target directory below target_home; defaults to src. strftime placeholders are supported.
delete_extra	Delete files in the target that do not exist in the source. Defaults to true.
exclude	Extra exclude patterns for this command only.

Notes

• src and target must stay within src_home and target_home after path resolution.
• src_home or target_home may be omitted from the configuration, but every missing value must then be supplied when running (via CLI parameters).
• Exactly one of --src-home - and --target-home - may read from standard input in a single run.
• If backup is omitted, yd creates a timestamped backup directory automatically unless --no-backup is specified.
• If a configured source directory exists but is empty, yd reports that no synchronization was performed for that command. E.g., forgetting to mount an external drive does not delete all corresponding copies on harddrive).

Run a config

Run a saved configuration by name:

yd run photos

Options

Option	Meaning
--dry-run	Show what would happen without changing files.
--no-backup	Disable backup handling for this run.
--keep-newer	Skip updates when the target file is newer.
--rename-speedup	Enable rsync options tuned for rename-heavy targets. This may require more disk space on the target.
--src-home PATH	Override src_home from the config. Use - to read the value from standard input.
--target-home PATH	Override target_home from the config. Use - to read the value from standard input.

List configs

List available configurations with:

yd ls

This shows the configuration name together with the optional leading-comment description.

Why yd?

• Has one character from synchronize and one from directory.
• Easy to type with both QWERTZ and QUERTY keyboards.
• Name was still available on PyPI.
