How do I extract the contents of an rpm?
Did you try the rpm2cpio commmand? See the example below:
$ rpm2cpio php-5.1.4-1.esp1.x86_64.rpm | cpio -idmv/etc/httpd/conf.d/php.conf ./etc/php.d ./etc/php.ini ./usr/bin/php ./usr/bin/php-cgi etc
$ mkdir packagecontents; cd packagecontents$ rpm2cpio ../foo.rpm | cpio -idmv$ find . For Reference: the cpio arguments are
-i = extract-d = make directories-m = preserve modification time-v = verboseI found the answer over here: lontar's answer
For those who do not have rpm2cpio, here is the ancient rpm2cpio.sh scriptthat extracts the payload from a *.rpm package.
Reposted for posterity … and the next generation.
Invoke like this: ./rpm2cpio.sh .rpm | cpio -dimv
