Systems and methods for improved command line interface (CLI) auto-completion. According to one embodiment, a command auto-complete assistant running on a network security device receives input text entered by a user via a command line interface (CLI) console associated with the network security device. A list of auto-complete suggestions is determined by the command auto-complete assistant by matching the input text with multiple commands of a command set based on a matching condition. A score is calculated by the command auto-complete assistant for each auto-complete suggestion in the list of auto-complete suggestions based on at least one priority weighting factor. The list of auto-complete suggestions is sorted by the command auto-complete assistant based on their respective scores. At least one of the sorted auto-complete suggestions is displaying by the command auto-complete assistant on the CLI console.
