Python Library

Python Library

Simple Script Fetching

from shebangrun import run

# Fetch a script (returns content as string)
content = run(username="mpruitt", script="bashtest")
print(content)

Execute Python Scripts

from shebangrun import run

# Fetch and execute with confirmation prompt
run(username="mpruitt", script="myscript", eval=True)

# Execute without confirmation (use with caution!)
run(username="mpruitt", script="myscript", eval=True, accept=True)

Working with Versions

from shebangrun import run

# Get latest version
content = run(username="mpruitt", script="deploy", version="latest")

# Get specific version
content = run(username="mpruitt", script="deploy", version="v5")

# Get tagged version
content = run(username="mpruitt", script="deploy", version="dev")

Private Scripts

from shebangrun import run

# Access private script with share token
content = run(
    username="mpruitt", 
    script="private-script",
    token="your-share-token-here"
)

Full API Client

For more advanced usage, use the ShebangClient class:

from shebangrun import ShebangClient

# Initialize client
client = ShebangClient(url="shebang.run")

# Login
client.login(username="myuser", password="mypassword")

# Create a script
client.create_script(
    name="hello",
    content="#!/bin/bash\necho 'Hello World'",
    description="My first script",
    visibility="public"
)

# List your scripts
scripts = client.list_scripts()
for script in scripts:
    print(f"{script['name']} - v{script['version']}")

# Update a script (creates new version)
client.update_script(
    script_id=1,
    content="#!/bin/bash\necho 'Hello World v2'",
    tag="dev"
)

# Generate share token for private script
token = client.generate_share_token(script_id=1)
print(f"Share URL: https://shebang.run/myuser/myscript?token={token}")

# Get script metadata
meta = client.get_metadata(username="mpruitt", script="bashtest")
print(f"Version: {meta['version']}, Size: {meta['size']} bytes")

# Verify signature
verification = client.verify_signature(username="mpruitt", script="bashtest")
print(f"Signed: {verification['signed']}")

Key Management

from shebangrun import ShebangClient

client = ShebangClient(url="shebang.run")
client.login(username="myuser", password="mypassword")

# Generate a new keypair
key = client.generate_key(name="my-signing-key")
print(f"Public Key: {key['public_key']}")
print(f"Private Key: {key['private_key']}")  # Save this securely!

# List keys
keys = client.list_keys()
for key in keys:
    print(f"{key['name']} - Created: {key['created_at']}")

# Import existing public key
client.import_key(
    name="imported-key",
    public_key="-----BEGIN PUBLIC KEY-----\n..."
)

# Delete a key
client.delete_key(key_id=1)

Account Management

from shebangrun import ShebangClient

client = ShebangClient(url="shebang.run")
client.login(username="myuser", password="mypassword")

# Change password
client.change_password(
    current_password="oldpass",
    new_password="newpass"
)

# Export all data (GDPR)
data = client.export_data()
print(f"Exported {len(data['scripts'])} scripts")

# Delete account (permanent!)
client.delete_account()

API Reference

• get_metadata(username, script) - Get script metadata
• verify_signature(username, script) - Verify script signature
• create_script(name, content, description="", visibility="private", keypair_id=None) - Create script

Security Notes

⚠️ Warning: Using eval=True with accept=True will execute remote code without confirmation. Only use this with scripts you trust completely.

✅ Best Practices:

• Always review scripts before executing with eval=True
• Use accept=False (default) to see the script before execution
• Store private keys securely, never commit them to version control
• Use environment variables for tokens and credentials
• Verify script signatures when available

Examples

Automation Script

#!/usr/bin/env python3
from shebangrun import run

# Fetch deployment script and execute with confirmation
run(
    username="devops",
    script="deploy-prod",
    version="latest",
    eval=True,
    accept=False  # Always confirm production deployments!
)

CI/CD Integration

import os
from shebangrun import ShebangClient

client = ShebangClient()
client.login(
    username=os.environ["SHEBANG_USER"],
    password=os.environ["SHEBANG_PASS"]
)

# Update deployment script
client.update_script(
    script_id=int(os.environ["DEPLOY_SCRIPT_ID"]),
    content=open("deploy.sh").read(),
    tag="latest"
)

print("Deployment script updated!")
