When writing scripts for other shells, it can be confusing and annoying that our `man` function shadows other manual pages, for example `exec(1p)` from [Linux man-pages]. I almost never want to see the fish variant for such contended cases (which obviuosly don't include fish-specific commands like `string`, only widely-known shell builtins). For the contented cases like `exec`, the POSIX documentation is more substantial and useful, since it describes a (sub)set of languages widely used for scripting. Because of this I think we should stop overriding the system's man pages. Nowadays we offer `exec -h` as intuitive way to show the documentation for the fish-specific command (note that `help` is not a good replacement because it uses a web browser). Looking through the contended commands, it seems like for most of them, the fish version is not substantially different from the system version. A notable exception is `read` but I don't think it's a very important one. So I think we should can sacrifice a bit of the native fish-scripting experience in exchange for playing nicer with other shells. I think the latter is more important because scripting is not our focus, the way I see it. So maybe put our manpath at the end. In lieu of that, let's at least have `exec.rst` reference the system variant. [Linux man-pages]: https://www.kernel.org/doc/man-pages/ Closes #10376

Description

|
-----------
|
|
|
|
.. only:: builder_man
|
|
|
|
NOTE: This page documents the fish builtin ``exec``.
|
|
To see the documentation on any non-fish versions, use ``command man exec``.
|
|
|
|
``exec`` replaces the currently running shell with a new command. On successful completion, ``exec`` never returns. ``exec`` cannot be used inside a pipeline.
|
|
|
|
The **--help** or **-h** option displays help about using this command.
|
|
|
|
Example
|
|
-------
|
|
|
|
``exec emacs`` starts up the emacs text editor, and exits ``fish``. When emacs exits, the session will terminate.
