podman-generate-systemd- Generate Systemd Unit file
## SYNOPSIS
-**podman generate systemd** [*options*] *container*
+**podman generate systemd** [*options*] *container|pod*
## DESCRIPTION
-**podman generate systemd** will create a Systemd unit file that can be used to control a container. The
-command will dynamically create the unit file and output it to stdout where it can be piped by the user
-to a file. The options can be used to influence the results of the output as well.
+**podman generate systemd** will create a systemd unit file that can be used to control a container or pod.
+By default, the command will print the content of the unit files to stdout.
Note that this command is not supported for the remote client.
## OPTIONS:
+**--files**, **-f**
+
+Generate files instead of printing to stdout. The generated files are named {container,pod}-{ID,name}.service and will be placed in the current working directory.
+
**--name**, **-n**
Use the name of the container for the start, stop, and description in the unit file
