What is the fish equivalent?

Solution

  • Fish use a similar flag system:

    fish -d 3 script.fish

    Where d is the debug flag followed by the verbosity level:

    -d or --debug-level=DEBUG_LEVEL specify the verbosity level of fish. A higher number means higher verbosity. The default level is 1.
