cpio & rpm2cpio commands

To extract a cpio file:
cpio -iv < cpio_file

To list the contents of a cpio file:
cpio -itv < cpio_file

To create a .cpio file with all files in the current directory:
ls | cpio -o > cpio_file

To extract all files from an RPM:
rpm2cpio RPM_file | cpio -idv

To extract individual file(s) from an RPM:
rpm2cpio RPM_file | cpio -id individual_file(s)

ex. Extracting libcrypto.so.0.9.7a and libssl.so.0.9.7a from openssl-0.9.7a-2.i386.rpm:
cpio -itv < openssl-0.9.7a-2.i386.cpio | egrep "libcrypto.so.0.9.7a|libssl.so.0.9.7a"

-rwxr-xr-x   1 root     root       992092 Feb 27 12:10 ./lib/libcrypto.so.0.9.7a
-rwxr-xr-x   1 root     root       216004 Feb 27 12:10 ./lib/libssl.so.0.9.7a

rpm2cpio openssl-0.9.7a-2.i386.rpm | cpio -idv ./lib/libssl.so.0.9.7a ./lib/libcrypto.so.0.9.7a

This will extract the two files from the RPM into a ./lib subdirectory.
