## The exit status can only be one integer 0-255. Use stdout for other data.
|
||||||
|
|
||||||
|
### Problematic code:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
exit foo bar
|
||||||
|
```
|
||||||
|
|
||||||
|
### Correct code:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
echo foo
|
||||||
|
echo bar
|
||||||
|
exit
|
||||||
|
```
|
||||||
|
|
||||||
|
### Rationale:
|
||||||
|
|
||||||
|
In bash, `exit` can only be used to signal success or failure (0 = success, 1-255 = failure).
|
||||||
|
|
||||||
|
To exit with textual or multiple values from a function, write them to stdout and capture them with command substitution instead.
