## Exit Status
The exit code from `podman gives information about why the container
failed to run or why it exited. When `podman` commands exit with a non-zero code,
the exit codes follow the `chroot` standard, see below:
**_125_** if the error is with podman **_itself_**
$ podman run --foo busybox; echo $?
# flag provided but not defined: --foo
See 'podman run --help'.
125
**_126_** if executing a **_container command_** and the the **_command_** cannot be invoked
$ podman run busybox /etc; echo $?
# exec: "/etc": permission denied
podman: Error response from daemon: Contained command could not be invoked
126
**_127_** if executing a **_container command_** and the the **_command_** cannot be found
$ podman run busybox foo; echo $?
# exec: "foo": executable file not found in $PATH
podman: Error response from daemon: Contained command not found or does not exist
127
**_Exit code_** of **_container command_** otherwise
$ podman run busybox /bin/sh -c 'exit 3'
# 3
