NAME

undist — unpack, list, or verify SGI dist archives

SYNOPSIS

undist [-l|-v|-x] [-aopst] [-m machtype] [-P prefix] dist.idb

undist unpacks SGI dist archives, which are found on IRIX installation media.

undist runs in one of three mutually exclusive modes:

-l: List the archive's contents without extracting.
-v: Verify the archive's contents by calculating and comparing checksums (after decompressing, if necessary), without saving any files.
-x: Extract the archive's contents.

The following flags augment one or more of the above modes:

-a: Allow extraction to an absolute path. Otherwise, files are extracted relative to the current working directory.
-m machtype: Extract only files whose mach field in the idb file exactly match the given string.
-o: Ignore offset fields in the idb file and compute each manually. Mainly for testing.
-P prefix: Only extract files whose names begin with the given prefix. There is currently no globbing support.
-p: Allow extraction to relative paths such as ‘../’. Otherwise, relative paths are munged such that files are extracted only within the current working directory and subdirectories thereof.
-s: Skip extraction errors and try to continue. Otherwise, fails immediately when an error is encountered.
-t: Extract using the temporary file path in the idb file instead of the destination file path.

Extract all contents from a dist into the current working directory:

undist -x
  /mnt/dist/eoe1.idb

List all contents in a dist:

undist -l
  /mnt/dist/eoe1.idb

Verify sizes and checksums of all files in a dist:

undist -v
  /mnt/dist/eoe1.idb

Extract a single file from a dist:

undist -x -P usr/etc/audio/hdsp.lod
  /mnt/dist/dmedia_eoe.idb

The undist utility first appeared in NetBSD 12.
