#### Join
|
|
|
|
|
|
|
|
|
|
Combine text vertically or horizontally with a single command, use this command
|
|
|
|
|
with `gum style` to build layouts and pretty output.
|
|
|
|
|
|
|
|
|
|
Note: It's important to wrap the output of `gum style` in quotes to ensure new
|
|
|
|
|
lines (`\n`) are part of a single argument passed to the `join` command.
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
gum join "$(gum style --padding "1 5" --border double "I love Bubble Gum")" "$(gum style --padding "1 5" --border double "<3")"
|
|
|
|

```
