Proton Drive CLI launches for cross-platform encrypted file management

Proton Drive CLI: The Official Cross-Platform Encrypted Cloud Storage Command Line Tool

Managing encrypted cloud storage straight from your terminal just got real. Proton Drive CLI, the first official command line interface for Proton Drive, delivers full-featured, cross-platform file management and automation for privacy-minded developers. With native binaries for Windows, macOS, and Linux, this CLI enables scripting and automation capabilities that fundamentally change how you interact with encrypted cloud data. If you're already a terminal power user or looking to automate secure backups and sharing without leaving the command line, Proton Drive CLI covers the core workflows — and sets the stage for more.

What is Proton Drive CLI and why does it matter?

Proton Drive CLI is Proton’s cross-platform command line interface for encrypted cloud storage, designed to run natively on Windows, macOS, and Linux. This tool isn’t just a filesystem wrapper — it enables encrypted file management, privacy-first automation, and bulk scripting that were previously locked up behind a web UI.

The CLI goes beyond basic file moves: it offers a secure, scriptable entry point for everything from uploading big folders without re-uploading what’s already there, to auditing share permissions, to smoothly exporting structured metadata (with --json) for your own backup, compliance, or migration jobs. All of this runs locally, on your hardware, with the operating system’s credential storage ensuring secrets never leak.

For privacy demands, there’s not much out there that rivals Proton Drive’s end-to-end encrypted cloud storage, and the CLI finally delivers the programmatic access developers expect. The CLI lands as Proton completes a full engine rewrite, making Drive reportedly 3× faster across the board — so scripted automation doesn’t hit legacy bottlenecks anymore.

How to install Proton Drive CLI on Windows, macOS, and Linux

Getting started is simple and fast. Proton Drive CLI ships as downloadable pre-built binaries for all three major operating systems, so there’s zero need to wrestle with dependency trees or language runtimes. Here’s how to get rolling on each platform:

On macOS and Linux:

1. Download the binary for your system from Proton’s release portal or official repository.

2. Open your terminal and make the downloaded file executable:
   

   chmod +x proton-drive
   

3. (Optional but standard) Move it to a location on your $PATH for global use.

4. Launch the CLI to begin authentication.

When you start Proton Drive CLI for the first time, it opens a browser window for you to authenticate — you never have to paste secrets into the terminal. Your login session is then handed off to your OS's native keychain (macOS Keychain, Linux secrets backend).

On Windows:

• Download the .exe binary installer from Proton, run it, and follow the prompts. Proton Drive CLI will store credentials securely in Windows Credential Manager, out of reach of scripts or accidental leaks.

Session management

• Repeat authentication isn’t required: your session keys persist securely and are locked into the keychain or credential store. For automation on CI or ephemeral hosts, build explicit login steps into your workflow to avoid failed executions.

Advanced: building from source

• For those preferring or needing a custom build, copy the repo locally, install dependencies with Bun, and compile the TypeScript source. But for production or automation, the signed binaries are the path of least friction.

Proton Drive CLI core commands you need to know

The CLI isn’t a toy wrapper — it exposes most of the file logic you get from the web UI, mapping directly to developer workflows:

Authentication — initialize the CLI session:

proton-drive auth

This launches your default browser for secure OAuth-style login. After this, all CLI commands operate as your authenticated user.

List directories and contents (recursive):

proton-drive ls /my-folder
proton-drive ls --recursive /my-folder

Get a view on any drive location, optionally flattening folders recursively. Output can be exported as structured JSON for scripts:

proton-drive ls /my-folder --json

Upload documents, skipping existing:

proton-drive upload local-dir/ /drive/folder --skip-existing

This only uploads new or changed files, saving bandwidth and time in repeat backups or batch jobs.

Move files to the trash:

proton-drive trash /drive/folder/old-report.pdf

Removes a target file or folder, mirroring web UI trash behavior — useful for automated retention enforcement.

Download remote folders:

proton-drive download /drive/folder-to-save local-folder/

Back your cloud files into a local directory, perfect for scripted daily or weekly snapshots.

Check sharing status and permissions:

proton-drive share status /drive/shared-folder --json

Returns current collaborators, permission levels, invite status — either in console or machine-readable output.

Invite a collaborator (with editor access and custom message):

proton-drive share invite /drive/shared-folder --email [e-mail] --role editor --message "Join for Q2 planning"

Script invite flows as part of onboarding or automation pipelines.

General tip: every core command supports a --json flag so you can pass data directly into other shell or programming tools (jq, Python scripts, GitHub Actions).

How to automate cloud storage tasks using Proton Drive CLI

All key Proton Drive CLI commands are built for scripting and automation, letting you manage encrypted storage as part of any workflow. The CLI’s standards-based approach means everything composable by design.

Structured outputs for integrations

Use the --json flag to generate structured responses for any command, enabling direct piping into processing scripts:

proton-drive ls /project --json | jq '.files[] | select(.type=="document") | .name'

Great for inventory reports, compliance exports, or invoking downstream automation.

Setup cron jobs for scheduled backups

On Linux/macOS, schedule regular, incremental backups of a directory with cron. Example (daily midnight archive):

0 0 * * * /usr/local/bin/proton-drive upload /srv/daily-records /drive/backups --skip-existing

On Windows, mirror this via Task Scheduler using the CLI .exe in a bat or PowerShell script.

Handle sharing and invites programmatically

Automate share-invite flows with shell scripts:

proton-drive share invite /team-folder --email [e-mail] --role editor --message "Auto-invite for new engineer"

Ideal for IT onboarding or provisioning.

Scripting/automation benefits

• Eliminate manual drag-and-drop labor.
• Ensure backup policies actually run, without human error.
• Pipe outputs into notification bots, dashboards, or monitoring.
• All executed under Proton’s end-to-end encryption.

What features are coming next to Proton Drive CLI?

Proton has already confirmed a major roadmap for the Drive CLI, building beyond the core file/folder operations to compete toe-to-toe with cloud incumbents on developer ergonomics.

Announced upcoming features:

• Photo management: Expect native handling for uploaded photos, not just raw files.
• Secure public link sharing: CLI support for generating end-to-end encrypted public links for files/folders.
• Custom albums: Create and manage photo albums right from the terminal for automated organization.
• Multiple account switching: smoothly swap which Proton Drive account the CLI is authorized for (critical for contractors, test vs prod, or managed devices).

This roadmap is pulled directly from Proton team statements via their Neowin release announcement, and positions the CLI as a long-term interface — not a one-off sidecar project.

Troubleshooting and best practices for using Proton Drive CLI

Launching a CLI for encrypted cloud storage introduces both usability and operational questions. Here are reliable ways to debug and maximize value.

Authentication and session security

• Always run proton-drive auth on first use or after session expiry — do not attempt to pass tokens in via env.
• Let the CLI interact with the browser for the first step; this avoids leaking secrets into process logs.

Credential storage

• Rely on the OS credential manager (macOS Keychain, Windows Credential Manager, Linux credential store).
• Never hardcode secrets in scripts or CI configs. The CLI was built to avoid this exposure.

Common issues

• Failed uploads? Double check --skip-existing if you’re automating; otherwise, retries may overwrite or bloat storage.
• Trouble with download paths? Use absolute paths, and validate folder permissions for system accounts.
• For JSON outputs, validate schema compatibility if integrating into strict parsers (e.g., CI/CD workflows).
• For strange errors, updating to the latest CLI binary resolves most environment glitches.

Integration best practices

• Chain with native OS commands (rsync, Windows copy) for pre-sync scrubbing or deduplication.
• Use shell exit codes to gate further automation steps.
• Store versioned exports with timestamps for auditability.

Conclusion: a durable automation layer for encrypted storage

Proton Drive CLI delivers a modern, cross-platform, and secure layer for managing encrypted files directly from the terminal. With official support for Windows, macOS, and Linux, and focused on privacy-first workflows, it allows developers and sysadmins to finally automate encrypted cloud tasks with the trust and flexibility they expect. Throw in forthcoming features like photo handling, public link generation, and account switching, and it’s clear Proton’s CLI isn’t a checkbox — it’s a real foundation.

The CLI is built to persist, even as the underlying features and speeds improve — use it in your automation today, and know your config and scripts will keep working as Drive evolves underneath.
