## Exit Status

The exit code from `podman exec` gives information about why the command within the container failed to run or why it exited.  When `podman exec` exits with a
non-zero code, the exit codes follow the `chroot` standard, see below:

  **125** The error is with Podman itself

    $ podman exec --foo ctrID /bin/sh; echo $?
    Error: unknown flag: --foo
    125

  **126** The _contained command_ cannot be invoked

    $ podman exec ctrID /etc; echo $?
    Error: container_linux.go:346: starting container process caused "exec: \"/etc\": permission denied": OCI runtime error
    126

  **127** The _contained command_ cannot be found

    $ podman exec ctrID foo; echo $?
    Error: container_linux.go:346: starting container process caused "exec: \"foo\": executable file not found in $PATH": OCI runtime error
    127

  **Exit code** The _contained command_ exit code

    $ podman exec ctrID /bin/sh -c 'exit 3'; echo $?
    3

## EXAMPLES

```
$ podman exec -it ctrID ls
$ podman exec -it -w /tmp myCtr pwd
$ podman exec --user root ctrID ls
