## NAME
|

|
|
|
|
## SYNOPSIS
|
|
**podman history** [*options*] *image*[:*tag*|@*digest*]
|
|
|
|
**podman image history** [*options*] *image*[:*tag*|@*digest*]

## DESCRIPTION
|
|
**podman history** displays the history of an image by printing out information
|
|
about each layer used in the image. The information printed out for each layer
|
|
include Created (time and date), Created By, Size, and Comment. The output can
|
|
be truncated or not using the **--no-trunc** flag. If the **--human** flag is
|
|
set, the time of creation and size are printed out in a human readable format.
|
|
The **--quiet** flag displays the ID of the image only when set and the **--format**
|
|
flag is used to print the information using the Go template provided by the user.
|
|
|
