rclone 1.0.0

A robust, typed Python wrapper for the rclone CLI.

Rclone for Python

🚀 A robust, typed Python wrapper for rclone.

It shells out to the rclone binary the safe way — every command is built as an argument list and run without a shell, so paths and remote specs are never re-interpreted. Common subcommands have explicit, typed methods that return structured results; anything else is one run() call away.

Highlights

• 🔒 No shell, no injection. Arguments are passed as a list — never a shell string.
• 🧱 Zero required dependencies. Pure standard library. tqdm is optional, only for progress bars.
• 🧩 Typed API + structured results. lsjson → list[dict], size → SizeResult, transfers → RcloneResult.
• 📊 Reliable progress. Driven by rclone's own JSON stats log (works for remote destinations too), not by guessing file sizes.
• 💥 Real errors. Non-zero exits raise RcloneCommandError carrying the exit code, its meaning, and captured output.

Requirements

• 🐍 Python >= 3.8
• 📦 rclone on your PATH (or pass binary=... / set RCLONE_BINARY)

Installation

pip install rclone                # core, no third-party dependencies
pip install "rclone[progress]"    # adds tqdm for progress bars

Quick start

from rclone import Rclone

rc = Rclone()                     # finds rclone on PATH

rc.copy("foo.txt", "remote:/path/to/dst")
rc.ls("remote:/path/to/dir")      # ['foo.bin', 'bar.txt', 'foo/']
rc.size("remote:/path/to/dir")    # SizeResult(count=5, bytes=170397, sizeless=0)

The legacy import path still works: from rclone.rclone import Rclone.

Examples

Transfers with progress

# A tqdm progress bar (requires the `progress` extra):
rc.copy("bigfile.bin", "remote:/backup", progress=True)

# Or your own callback, called on every stats tick:
def on_progress(stats):
    print(f"{stats.percentage}%  {stats.bytes}/{stats.total_bytes}  {stats.speed:.0f} B/s")

result = rc.move("data/", "remote:/archive", progress=on_progress)
print(result.success, result.stats.bytes)

Listing and info

rc.lsjson("remote:/dir")          # [{'Path': 'bar.txt', 'Name': 'bar.txt', 'Size': 0, 'IsDir': False}, ...]

size = rc.size("remote:/dir")
size.count, size.bytes            # also: size.total_objects, size.total_size (legacy aliases)

rc.about("remote:")               # {'total': ..., 'used': ..., 'free': ...}
rc.md5sum("remote:/dir")          # {'bar.txt': 'd41d8cd9...'}
rc.listremotes()                  # ['gdrive:', 's3:']
rc.version()                      # 'v1.74.3'

Extra flags

Pass any rclone flags as positional arguments to any method:

rc.ls("remote:/dir", "-R", "--max-depth", "2")
rc.copy("src/", "remote:/dst", "--transfers", "8", "--exclude", "*.tmp")

Content helpers

text = rc.cat("remote:/notes.txt")
rc.rcat("remote:/notes.txt", "written from python")   # reads from stdin

The escape hatch

Anything without a dedicated method is reachable via run() (returns an RcloneResult) — arguments are still passed safely as a list:

result = rc.run("dedupe", "remote:/dir", "--dedupe-mode", "newest")
print(result.returncode, result.stdout)

Configuration

rc = Rclone(
    binary="/usr/local/bin/rclone",   # explicit path (else $RCLONE_BINARY, else PATH)
    config="~/my-rclone.conf",        # passed as --config
    flags=["--fast-list"],            # global flags applied to every command
    debug=True,                       # log each command on the "rclone" logger
    timeout=600,                      # seconds, for non-streaming commands
)

Error handling

from rclone import Rclone, RcloneCommandError

rc = Rclone()
try:
    rc.copy("missing:", "remote:/dst")
except RcloneCommandError as exc:
    print(exc.returncode)   # e.g. 3
    print(exc.stderr)       # rclone's error output

# Or opt out of raising and inspect the result instead:
result = rc.check("a/", "b/")          # check() does not raise on differences
if not result.success:
    print("directories differ")

Migrating from 0.4.x

• Import is now from rclone import Rclone (the old from rclone.rclone import Rclone still works).
• The unit= constructor argument is gone; the progress bar auto-scales units (B/KB/MB/GB).
• Progress is opt-in per call via progress=True (bar) or progress=<callable> (callback) instead of being on by default.
• Listing/size now return structured types (list, SizeResult) and errors raise RcloneCommandError.
• delete() works normally — the old artificial block is gone (the unsafe dynamic dispatch that motivated it was removed).
• execute("...") is still available; new code should prefer run(...).
