About:
GNU Rush is a restricted shell designed for limiting user command execution and environment access. It provides robust security controls for shared systems by restricting users to a predefined set of commands and options. This makes it ideal for creating constrained guest or service accounts.
Key Features:
  • Configurable command restrictions
  • Built-in logging and auditing
  • Environment variable control
  • Fine-grained access control
Use Cases:
  • Securing shared hosting environments
  • Creating restricted service accounts
  • Educational lab access control
Alternatives:
  • rbash – Rush offers more granular configuration than the basic restricted bash shell
  • scponly – Rush provides more flexible command restriction capabilities
