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.
