Extract the cpio extension file

[Nikee Reddy]

Hello,

I have a file with an extention cpio. i.e. 9204_hpunix_Release.cpio

Do you guys know how to extract this file???

Thanks,
Nikee

File extensions are not necessarily significant in Unix. It may not be anything other than a plain text file. Try more or cat or strings and see what you get.

Just a guess, but I'd think cpio will probably expand it.

man cpio

file 9204_hpunix_Release.cpio

for more data.

man cpio .

or
cpio -ivmu < file.cpi

Hello,

Here is the output when I ran the file command on the cpio file:

# file 9204_hpunix_Release.cpio
9204_hpunix_Release.cpio: ASCII cpio archive

Still I did not have to clue to unpack this file?

Thanks,
Nikee

To extract you can use pax:

pax -rv < 9204_hpunix_Release.cpio

For the file in the cur dir to the cur dir use

cpio -icvdumB
