To enable tasks auto-completion in shell you should add eval "$(gulp --completion=shell)" in your .shellrc file.

Add eval "$(gulp --completion=bash)" to ~/.bashrc.

Zsh

Add eval "$(gulp --completion=zsh)" to ~/.zshrc.

Powershell

Add Invoke-Expression ((gulp --completion=powershell) -join [System.Environment]::NewLine) to $PROFILE.

Fish

Add gulp --completion=fish | source to ~/.config/fish/config.fish.
