Retrieves the fully resolved path to the currently executing fish binary (regardless of PATH). Can be used to ensure that the same fish is launched again from a script. `get_executable_path()` moved from fish binary to libfish, also cleaned up some duplicated (but differing!) definitions of PATH_MAX (which was used by that function) in the process.

\subsection status-description Description
|
|
|
|
With no arguments, `status` displays a summary of the current login and job control status of the shell.
|
|
|
|
The following operations (sub-commands) are available:
|
|
|
|
- `is-command-sub` returns 0 if fish is currently executing a command substitution. Also `-c` or `--is-command-substitution`.
|
|
|
|
- `is-block` returns 0 if fish is currently executing a block of code. Also `-b` or `--is-block`.
|
|
|
|
- `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` returns 0 if fish is interactive - that is, connected to a keyboard. Also `-i` or `--is-interactive`.
|
|
|
|
- `is-login` returns 0 if fish is a login shell - that is, if fish should perform login tasks such as setting up the PATH. Also `-l` or `--is-login`.
|
|
|
|
- `is-full-job-control` returns 0 if full job control is enabled. Also `--is-full-job-control` (no short flag).
|
|
|
|
- `is-interactive-job-control` returns 0 if interactive job control is enabled. Also, `--is-interactive-job-control` (no short flag).
|
|
|
|
- `is-no-job-control` returns 0 if no job control is enabled. Also `--is-no-job-control` (no short flag).
|
|
|
|
- `filename` prints the filename of the currently running script. Also `current-filename`, `-f` or `--current-filename`.
|
|
|
|
- `fish-path` prints the absolute path to the currently executing instance of fish.
|
|
|
|
- `function` prints the name of the currently called function if able, when missing displays "Not a
|
|
function" (or equivalent translated string). Also `current-function`, `-u` or `--current-function`.
|
|
|
|
- `line-number` prints the line number of the currently running script. Also `current-line-number`, `-n` or `--current-line-number`.
|
|
|
|
- `stack-trace` prints a stack trace of all function calls on the call stack. Also `print-stack-trace`, `-t` or `--print-stack-trace`.
|
|
|
|
- `job-control CONTROL-TYPE` sets the job control type, which can be `none`, `full`, or `interactive`. Also `-j CONTROL-TYPE` or `--job-control=CONTROL-TYPE`.
|
|
|
|
- `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.
|
|
|
|
\subsection status-notes Notes
|
|
|
|
For backwards compatibility each subcommand 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 3.0).
|
|
|
|
You can only specify one subcommand per invocation even if you use the flag form of the subcommand.
