what do i do with a .cpio file

[Donald Thaler]

I had a .cpio.gz file which i unzipped and it created a .tar file and a .cpio file. I know what to do with the .tar file, but what is the .cpio file. I thought I could do a cpio -t filename to print the table of contents but it didn't like the -t option???

Use something like this to extract the file:

cpio -idv < cpio_file

Hi Donald, you can extract cpio files in your current path using:

cpio -idmv < file

Where file is your .cpio file. To list file contents the sintaxis is:

cpio -t < file

Hi Donald,

Please use
cpio -itv < filename.cpio
to list the contents

Hi,

to get the content info of a cpio-archive use

cpio -itv
More info is found in 'man cpio'.

If you want to list the content of the file first, use:

cpio -it < file.cpio

[Donald Thaler]

When i do the cpio -itv i get the following error 'su: HPUNIX_GridControl_agent_download_10_2_0_1.cpio: Cannot find or open the file'

If i leave the '<' out nothing happens..

I'm positioned in the directory that has the .cpio file...

I'm logged in as the owner of the directory that has the .cpio file..

Hi,

please send the outout of
ls -l *.cpio

Donald,

Also do a
file filename.cpio
to check its showing a cpio archive.

Why is there an "su:" in your error message?

[Steve Post]

The first thing you should do is "man cpio".

The second thing is perhaps you need a "./" in front of the filename.
I.e.
cpio -itdumvc < ./HP_text_text.cpio

To make a cpio file
find . -print | cpio -odumvc > ./file.cpio

To read file LISTING from a cpio file.
cpio -itdumvc < ./file.cpio

To extract all stuff from a cpio file.
cpio -idumvc < ./file.cpio

c - Character format
B - block format
Bc - a little of both?
I just try cpio with and without c and B.
If you get an "out-of-phase" error, you are using the wrong option.
What do I mean?
try cpio -itdumvc < ./file
and cpio -itdumvB < ./file
and cpio -itdumvBc < ./file
and cpio -itdum < ./file

t - means list the stuff, don't extract it.
d - means make directories
u - means do it no matter what
m - means retain owner and modification time.
i - means read a file
o - means make a file
