@@ -29,13 +29,13 @@ The prompt string supports escape sequences for dynamic content:
| `\t`, `\T` | Last command runtime (milliseconds / human-readable) |
| `\s` | Shell name |
| `\e[...` | ANSI escape sequences for colors and styling |
| `\!name` | Execute a shell function and embed its output |
| `\@name` | Execute a shell function and embed its output |
The `\!` escape is particularly useful. It lets you embed the output of any shell function directly in your prompt. Define a function that prints something, then reference it in your prompt string:
The `\@` escape is particularly useful. It lets you embed the output of any shell function directly in your prompt. Define a function that prints something, then reference it in your prompt string:
```sh
gitbranch() { git branch --show-current 2>/dev/null; }
export PS1='\u@\h \W \!gitbranch \$ '
export PS1='\u@\h \W \@gitbranch \$ '
```
Additionally, `echo` now has a `-p` flag that expands prompt escape sequences, similar to how the `-e` flag expands conventional escape sequences.
