# The exit builtin command
|
|
|
|
## Synopsis
|
|
|
|
exit [N]
|
|
|
|
## Description
|
|
|
|
The `exit` command terminates the current shell (or script).
|
|
|
|
If `N` is given, the return code to the parent process is set to `N`. If
|
|
not, the returned status the the status of the most recently executed
|
|
command (i.e. `$?`).
|
|
|
|
A [trap](/commands/builtin/trap) on `EXIT` is executed before the shell
|
|
exits, except the executed `exit` command is part of an already running
|
|
trap.
|
|
|
|
### Options
|
|
|
|
There are no options.
|
|
|
|
### Exit status
|
|
|
|
Naturally, you can't ask for the exit status from within the shell that
|
|
executed the `exit` command, because the shell exits.
|
|
|
|
| Status | Reason |
|
|
|:-------|:---------------------------------------------------------------------------|
|
|
| 255 | invalid (e.g. non-numeric) argument - this staus is returned to the parent |
|
|
|
|
## Examples
|
|
|
|
### Exit the shell and explicitely set its exit status
|
|
|
|
exit 3
|
|
|
|
## Portability considerations
|
|
|
|
- if `N` is specified, but its value is not between 0 and 255
|
|
inclusively, the exit status is undefined.
