List content of an initramfs image
lsinitramfs [options] <initramfsfile> [<initramfsfile>]
The lsinitramfs command lists the content of given initramfs images. It allows one to quickly check the content of one (or multiple) specified initramfs files.
Display usage information and exit.
Display long and more verbose listing of initramfs content.
List initramfs content of current running kernel:
lsinitramfs /boot/initrd.img-$(uname -r)
List content of two initramfs files in verbose mode:
lsinitramfs -l /boot/vmlinuz-2.6.31-grml64 /boot/vmlinuz-2.6.33-grml64
lsinitramfs cannot deal with multiple-segmented initramfs images, such as those created when an early (uncompressed) initramfs with system firmware is prepended to the regular compressed initrams, or when overlay data is appended to the initramfs.
The initramfs-tools are written by Maximilian Attems <[email protected]> and numerous others.
