## Description

With no arguments, `status` displays a summary of the current login and job control status of the shell.

The following operations (subcommands) are available:

is-command-substitution, -c or --is-command-substitution

  Returns 0 if fish is currently executing a command substitution.

is-block, -b or --is-block

  Returns 0 if fish is currently executing a block of code.

is-breakpoint

  Returns 0 if fish is currently showing a prompt in the context of a breakpoint command. See also the fish_breakpoint_prompt function.

is-interactive, -i or --is-interactive

  Returns 0 if fish is interactive - that is, connected to a keyboard.

is-login, -l or --is-login

  Returns 0 if fish is a login shell - that is, if fish should perform login tasks such as setting up `PATH`.

is-full-job-control or --is-full-job-control

  Returns 0 if full job control is enabled.

is-interactive-job-control or --is-interactive-job-control

  Returns 0 if interactive job control is enabled.

is-no-job-control or --is-no-job-control

  Returns 0 if no job control is enabled.

current-command

  Prints the name of the currently-running function or command, like the deprecated `_` variable.

filename, current-filename, -f or --current-filename

  Prints the filename of the currently-running script. If the current script was called via a symlink, this will return the symlink. If the current script was received by piping into source, then this will return `-`.

basename

  Prints just the filename of the running script, without any path components before.

dirname

  Prints just the path to the running script, without the actual filename itself. This can be relative to `PWD` (including just “.”), depending on how the script was called. This is the same as passing the filename to `dirname(3)`. It’s useful if you want to use other files in the current script’s directory or similar.

fish-path

  Prints the absolute path to the currently executing instance of fish.

function or current-function

  Prints the name of the currently called function if able, when missing displays “Not a function” (or equivalent translated string).

line-number, current-line-number, -n or --current-line-number

  Prints the line number of the currently running script.

stack-trace, print-stack-trace, -t or --print-stack-trace

  Prints a stack trace of all function calls on the call stack.

job-control, -j or --job-control CONTROL_TYPE

  Sets the job control type to CONTROL_TYPE, which can be none, full, or interactive.

features

  Lists all available feature flags.

test-feature FEATURE

  Returns 0 when FEATURE is enabled, 1 if it is disabled, and 2 if it is not recognized.

## Notes

For backwards compatibility most subcommands can also be specified as a long or short option. For example, rather than `status is-login` you can type `status --is-login`. The flag forms are deprecated and may be removed in a future release (but not before fish 4.0).

You can only specify one subcommand per invocation even if you use the flag form of the subcommand.
