output.txt is 0KB and there is nothing in it.


Whereas this

Code:

rpm2cpio

rpm2cpio(1)							   User Commands						       rpm2cpio(1)

NAME
       rpm2cpio - convert Red Hat Package (RPM) to cpio archive

SYNOPSIS
       rpm2cpio [file.rpm]

DESCRIPTION
       The  rpm2cpio  utility converts the .rpm file specified as its sole argument to a cpio archive on standard output. (See NOTES.) If no argu-
       ment is given, an rpm stream is read from standard input. In both cases, rpm2cpio will fail and print a usage message if the standard  out-
       put is a terminal. Therefore, the output is usually redirected to a file or piped through the cpio(1) utility.

EXAMPLES
       Example 1: Converting an rpm file

       example% rpm2cpio Device3Dfx-1.1-2.src.rpm | cpio -itv
       CPIO archive found!
       -rw-r--r--   1 root  root    2635 Sep 13 16:39 1998, 3dfx.gif
       -rw-r--r--   1 root  root   11339 Sep 27 16:03 1998, Dev3Dfx.tar.gz
       -rw-r--r--   1 root  root    1387 Sep 27 16:04 1998, Device3Dfx-1.1-2.spec
       31 blocks

       Example 2: Converting from standard input

       example% rpm2cpio < Device3Dfx-1.1-2.src.rpm | cpio -itv
       CPIO archive found!
       -rw-r--r--   1 root  root    2635 Sep 13 16:39 1998, 3dfx.gif

       -rw-r--r--   1 root  root    1387 Sep 27 16:04 1998, Device3Dfx-1.1-2.spec
