UNMKINITRAMFS(8)

NAME
unmkinitramfs - extract content from an initramfs image

SYNOPSIS
unmkinitramfs [options] <initramfsfile> <directory>

DESCRIPTION
The unmkinitramfs command extracts the content of a given initramfs image using cpio. If the image contains multiple segments, each are passed to cpio in order.

OPTIONS

-h  Display usage information and exit.

-v  Display verbose messages about extraction.

USAGE EXAMPLES
Extract initramfs content of current running kernel:

unmkinitramfs /boot/initrd.img-$(uname -r) initramfs/

BUGS
unmkinitramfs cannot deal with multiple-segmented initramfs images, except where an early (uncompressed) initramfs with system firmware is prepended to the regular compressed initramfs.
