Podman remote clients don't support loading images from directories, this patch aims to make that clearer. This patch also aims to make it clearer that podman-load can load from URLs, directories and tar archives. Drop incorrect claims that --input is required on remote clients (stdin reading is supported) and avoid 'Linux only' wording since podman has native FreeBSD support.

## NAME
|
|
podman\-save - Save image(s) to an archive or directory
|
|
|
|
## SYNOPSIS
|
|
**podman save** [*options*] *name*[:*tag*]
|
|
|
|
**podman image save** [*options*] *name*[:*tag*]
|
|
|
|
## DESCRIPTION
|
|
**podman save** saves an image to a local file or directory.
|
|
**podman save** writes to STDOUT by default and can be redirected to a
|
|
file using the **output** flag. The **quiet** flag suppresses the output when set.
|
|
**podman save** saves parent layers of the image(s) and the image(s) can be loaded using **podman load**.
|
|
To export the containers, use the **podman export**.
|
|
Note: `:` is a restricted character and cannot be part of the file name.
|
|
|
|
**podman save** operates on *images*: the resulting archive (OCI or docker-archive) preserves the image's layers, history and tags, and is restored as the same image with **podman load**. This is different from **podman export**, which flattens a *container's* filesystem into a single-layer tarball with no image history. To capture a container's filesystem instead, see **podman-export(1)**.
