NAME
archive_impact − calculate file system impacts for tar, cpio, and pax archives
SYNOPSIS
/opt/ignite/lbin/archive_impact -t [ -g | -z ][-l level ][-b block_size][-f
fragment_size] tar_archive [ -? ]
/opt/ignite/lbin/archive_impact -c [ -g | -z ][-l level ][-b block_size][-f
fragment_size] cpio_archive [ -? ]
/opt/ignite/lbin/archive_impact -p [ -g | -z ][-l level ][-b block_size][-f
fragment_size] pax_archive [ -? ]
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 configu-
ration 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 configura-
tion file.
Note that any archives that are produced using relative path names are extracted relative to the "/" directory.
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 envi-
ronment variables. Help text and some command output not parsed by Ignite-UX will be left in the user’s
specified locale.
