shellselective

shellselective is a command-line utility designed to enhance the way users interact with shell commands. Its primary function is to provide a more selective and intuitive method for executing commands based on various criteria. Instead of simply running a command, shellselective allows users to define conditions that must be met before the command is executed. This can include factors such as the current directory, the operating system, the presence of specific files, or even the output of other commands.

The tool works by parsing a configuration file where users define their selective command rules. Each rule typically consists of a condition and an associated command. When a user attempts to execute a command that is managed by shellselective, the utility evaluates the defined rules. If a rule's condition is met, the associated command is executed. This provides a layer of abstraction and control over command execution, preventing accidental or unintended commands from running in sensitive environments.

shellselective can be particularly useful for automating tasks, enforcing best practices, or preventing errors in complex workflows. For instance, a user might configure shellselective to only allow a certain deployment command to run if the current branch is 'main' and a specific build artifact exists. This selective execution mechanism adds a safety net and streamlines operations by ensuring commands are only invoked when appropriate. Its open-source nature encourages community contributions and customization.
