[SOLVED] cpio : Unable to extract

fanoflq · 07-28-2016, 01:43 PM

Code:

user1@host ~/backup $ ls -al include.cpio 
ls: cannot access include.cpio: No such file or directory

user1@host ~/backup $ find /usr/include | cpio -o > include.cpio
35933 blocks

user1@host ~/backup $ ls -al include.cpio 
-rw-r--r--. 1 user1 user1 18397696 Jul 28 12:33 include.cpio

user1@host ~/backup $ mkdir cpio

Now I extract:

Code:

user1@host ~/backup $ cd cpio

# Extracting cpio file.
user1@host ~/backup/cpio $ cpio -i < ~/backup/include.cpio
# a bunch of lines were printed out.... e.g. 
... ... 
cpio: /usr/include/gssapi.h not created: newer or same age version exists
cpio: /usr/include/gmpxx.h not created: newer or same age version exists
cpio: /usr/include/cursslk.h not created: newer or same age version exists
35933 blocks


~/backup/cpio $ ls *.*
ls: cannot access *.*: No such file or directory

I am suppose to get those files extracted in
same folder where the extraction command was executed.

But it is trying to extract to original folder, /usr/include.

Why am I not able to extract the cpio file to current folder?

Solution, add option --no-absolute-filenames like so:

Quote:

~/backup/cpio $ cpio -id --no-absolute-filenames < ~/backup/include.cpio
cpio: Removing leading `/' from member names
35933 blocks

user1@host ~/backup/cpio $ cd usr
user1@host ~/backup/cpio/usr $ cd include/
user1@host ~/backup/cpio/usr/include $ ls -al | wc -l
191

user1@host /usr/include $ ls -al | wc -l
191

Try --no-absolute-filenames option

Code:

`--no-absolute-filenames'
     Create all files relative to the current directory in copy-in
     mode, even if they have an absolute file name in the archive.
