\subsection fish_prompt-description Description
|
||
|
|
|
||
|
|
By defining the `fish_prompt` function, the user can choose a custom prompt. The `fish_prompt` function is executed when the prompt is to be shown, and the output is used as a prompt.
|
||
|
|
|
||
|
|
The exit status of commands within `fish_prompt` will not modify the value of <a href="index.html#variables-status">$status</a> outside of the `fish_prompt` function.
|
||
|
|
|
||
|
|
`fish` ships with a number of example prompts that can be chosen with the `fish_config` command.
