UNMKINITRAMFS(8)             System Administration            UNMKINITRAMFS(8)

NAME
       unmkinitramfs - extract content from an initramfs image

SYNOPSIS
       unmkinitramfs [-v] initramfs-file directory
       unmkinitramfs -h

DESCRIPTION
       The unmkinitramfs command extracts the content of a given initramfs im-
       age 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, ex-
       cept where an early (uncompressed) initramfs with  system  firmware  is
       prepended to the regular compressed initramfs.
