Questions tagged [fabric]

A Python library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.

Fabric provides a basic suite of operations for executing local or remote shell commands (normally or via sudo) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution.

Typical use involves creating a Python module containing one or more functions, then executing them via the fab command-line tool.
