DESCRIPTION
archive_impact
is run to calculate the per file system disk space
impacts for a given cpio,
pax, or tar archive. archive_impact
writes its results as impacts lines in Ignite-UX
configuration file format to
stdout
. Results may be redirected to an Ignite-UX configuration file and
then included in a
sw_sel statement. See instl_adm (4) for details on the syntax of the Ignite-UX
configuration file.
Note that any archives that are produced using relative path names are extracted relative to the "/" direc-
tory. When
archive_impact encounters a relative path name, it maps it relative to "/".
Options
archive_impact recognizes the following options:
-t The archive being processed is in tar format. Either this option, the -c option or
the -p option must be specified. tar format is the default for make_sys_image
archives.
-c The archive being processed is in cpio format. Either this option, the -t option
or the -p option must be specified.
-p The archive being processed is in pax format. Either this option, the -t option or
the -c option must be specified.
-g The archive has been compressed using gzip.
-z The archive has been compressed using compress.
-l level Determines for what level in the file system hierarchy to build impacts state-
ments. For example, if level is 1, impacts statements would be generated for
/usr and /var.Iflevel is 2, impacts statements would be generated for
/usr/local, /usr/bin, etc. It is not recommended to specify a level greater
than 2 for performance reasons. The default is 1.
-b block_size Set the default file system block size to use for size calculations. The default is
8192.
-f fragment_size
Set the default file system fragment size to use for size calculations. The default is
1024.

Note: The -b and -f options are left for compatibility only. They are deprecated as of Ignite-UX
version C.6.0.
International Code Set Support
Ignite-UX uses a variety of system commands to accomplish its functionality. Because the output of many
of these commands is parsed, Ignite-UX ensures that the POSIX locale is normally used by modifying
environment variables. Help text and some command output not parsed by Ignite-UX will be left in the
user’s specified locale.
EXAMPLES
Generate file system
impacts for the gzip compressed tar archive named mysys.tar.gz :
archive_impact -t -g mysys.tar.gz
