decompressing initrd

I have a simple question.I want to know how to decompress initrd image so that i can view its contents.Also if someone can tell me how to decompress the vmlinuz image it would be of great help.

Thanks in advance,

If you do a

Code:

file /path/to/file

on either file it should tell you the compression used then you can decompress like that.

I think when i looked at initrds on fedora core it was cpio compression so thats a possibility.

edit: I just checked mine now and the commands needed were

Code:

cp /boot/initrd-blah .

mv initrd-blah initrd-blah.gz

gzip -d initrd-blah.gz

cpio -i < initrd-blah

Those will extract the contents into the current directory so i would advise doing it in a new empty directory.

Thanks,it worked for me.
