man-pages(7) has [1]: > For commands, this shows the syntax of the command and its arguments > (including options); boldface is used for as-is text and italics are > used to indicate replaceable arguments. Brackets ([]) surround > optional arguments, vertical bars (|) separate choices, and ellipses > (...) can be repeated. I've adjusted our SYNOPSIS entries to match that formatting, and generally tried to make them more consistent with the precedent set by the man-pages project. Outside of the SYNOPSIS entry, I prefer using backticks for literals, although in some places I've left the ** bolding to keep things visually similar to a nearby SYNOPSIS entry.

## NAME
|
|
podman\-commit - Create new image based on the changed container
|
|
|
|
## SYNOPSIS
|
|
**podman commit** [*options*] *container* *image*
|
|
|
|
## DESCRIPTION
|
|
`podman commit` creates an image based on a changed container. The author of the
|
|
image can be set using the `--author` flag. Various image instructions can be
|
|
configured with the `--change` flag and a commit message can be set using the
|
|
`--message` flag. The container and its processes are paused while the image is
|
|
committed. This minimizes the likelihood of data corruption when creating the new
|
|
image. If this is not desired, the `--pause` flag can be set to false. When the commit
|
|
is complete, podman will print out the ID of the new image.
|
|
|
|
If *image* does not begin with a registry name component, `localhost` will be added to the name.
|
|
|
|
