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 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.
