Hey there! Let’s sort out your fish shell timestamp needs — first removing that right-side timestamp, then customizing it to match your desired style.

移除右侧时间戳

Fish shell’s right-side prompt is controlled by the fish_right_prompt function. Here’s how to ditch the timestamp:

Open the function editor for the right prompt:
```
funced fish_right_prompt
```
Look for any lines that generate the timestamp — they’ll usually involve date or a pre-defined timestamp variable. Delete those lines entirely.
Save your changes to make them permanent:
```
funcsave fish_right_prompt
```
Either restart your terminal or run source ~/.config/fish/config.fish to apply the changes immediately.

If you’re using a fish theme (like Oh My Fish’s bobthefish), check the theme’s configuration first — many themes have a toggle for the right prompt timestamp (e.g., set -g theme_show_right_prompt no for bobthefish).

自定义时间戳为目标样式

Let’s build a custom timestamp that matches your desired look (we’ll use a common styled example, which you can tweak further):

Reopen the right prompt editor:
```
funced fish_right_prompt
```
Replace the existing content (or add this if starting fresh) with code that defines your custom timestamp. For example, this creates a bracketed, gray-background white-text timestamp:
```
# Custom timestamp: gray background, white text, [HH:MM:SS] format
echo -n (set_color -b brblack white) "["(date '+%H:%M:%S')"]"(set_color normal)
```
Quick breakdown:
- set_color -b brblack white: Sets a soft gray background and white text for the timestamp
- date '+%H:%M:%S': Generates time in 24-hour format (adjust to '%I:%M %p' for 12-hour AM/PM, or '%Y-%m-%d %H:%M' to add the date)
- (set_color normal): Resets colors back to your terminal’s default after the timestamp
Save the function:
```
funcsave fish_right_prompt
```
Test it out by running any command — your new styled timestamp should appear on the right side instantly!
