.SH NAME
.PP
containers-storage diff - Generate a layer diff

.SH SYNOPSIS
.PP
\fBcontainers-storage\fP \fBdiff\fP [\fIoptions\fP [...]] \fIlayerNameOrID\fP

.SH DESCRIPTION
.PP
Generates a layer diff representing the changes made in the specified layer.
If the layer was populated using a layer diff, the result aims to be
bit-for-bit identical with the one that was applied, including the type of
compression which was applied.

.SH OPTIONS
.PP
\fB-f | --file\fP \fIfile\fP

.PP
Write the diff to the specified file instead of stdout.

.PP
\fB-c | --gzip\fP

.PP
Force the diff to be compressed using gzip compression.  If the layer was
populated by a layer diff, and that layer diff was compressed, this will be
done automatically.

.PP
\fB-u | --uncompressed\fP

.PP
Force the diff to be uncompressed.  If the layer was populated by a layer diff,
and that layer diff was compressed, it will be decompressed for output.
