No need to define "cmd-foo" anchors; use :doc:`foo <cmds/foo>`
instead. If we want "cmd-foo" but it should be tested.

fish_greeting - display a welcome message in interactive shells

Synopsis

|
|
|

fish_greeting

Description
|
|
-----------
|
|
|
|
When an interactive fish starts, it executes fish_greeting and displays its output.
|
|
|
|
The default fish_greeting is a function that prints a variable of the same name (``$fish_greeting``), so you can also just change that if you just want to change the text.
|
|
|
|
While you could also just put ``echo`` calls into config.fish, fish_greeting takes care of only being used in interactive shells, so it won't be used e.g. with ``scp`` (which executes a shell), which prevents some errors.
|
|
|
|
Example
|
|
-------
|
|
|
|
To just empty the text, with the default greeting function::
|
|
|
|
set -U fish_greeting
|
|
|
|
or ``set -g fish_greeting`` in :ref:`config.fish <configuration>`.
|
|
|
|
A simple greeting:
|
|
|
|
::
|
|
|
|
function fish_greeting
|
|
echo Hello friend!
|
|
echo The time is (set_color yellow)(date +%T)(set_color normal) and this machine is called $hostname
|
|
end
