compver - compatible versions file
DESCRIPTION
compver is an ASCII file used to specify previous versions of the associated package which are upward compatible. It is created by a pack-
age developer.
Each line of the file specifies a previous version of the associated package with which the current version is backward compatible.
Since some packages may require installation of a specific version of another software package, compatibility information is extremely cru-
cial. Consider, for example, a package called "A" which requires version "1.0" of application "B" as a prerequisite for installation. If
the customer installing "A" has a newer version of "B" (version 1.3), the compver file for "B" must indicate that "1.3" is compatible with
version "1.0" in order for the customer to install package "A".
EXAMPLES
Example 1: Sample compver file.
A sample compver file is shown below:
Version 1.3
Version 1.0

NOTES
The comparison of the version string disregards white space and tabs. It is performed on a word-by-word basis. Thus, "Version 1.3" and
"Version 1.3" would be considered the same.
The entries in the compver file must match the values assigned to the VERSION parameter in the pkginfo(4) files.

pkginfo(1) User Commands pkginfo(1)NAME
pkginfo - display software package information
SYNOPSIS
pkginfo [-q | -x | -l] [-p | -i] [-r] [-a arch] [-v version] [-c category...] [pkginst...]
pkginfo [-d device] [-R root_path] [-q | -x | -l] [-a arch] [-v version] [-c category...] [pkginst...]
DESCRIPTION
pkginfo displays information about software packages that are installed on the system (with the first synopsis) or that reside on a par-
ticular device or directory (with the second synopsis).
Without options, pkginfo lists the primary category, package instance, and the names of all completely installed and partially installed
packages. It displays one line for each package selected.
OPTIONS
The -p and -i options are meaningless if used in conjunction with the -d option.
The options -q, -x, and -l are mutually exclusive.
-a arch Specify the architecture of the package as arch.
-c category Display packages that match category. Categories are defined with the CATEGORY parameter in the pkginfo(4) file. If more
than one category is supplied, the package needs to match only one category in the list. The match is not case specific.
-d device Defines a device, device, on which the software resides. device can be an absolute directory pathname or the identifiers
for tape, floppy disk, removable disk, and so forth. The special token spool may be used to indicate the default installa-
tion spool directory (/var/spool/pkg).
-i Display information for fully installed packages only.
-l Specify long format, which includes all available information about the designated package(s).
-p Display information for partially installed packages only.
-q Do not list any information. Used from a program to check whether or not a package has been installed.
-r List the installation base for relocatable packages.
-R root_path Defines the full path name of a directory to use as the root_path. All files, including package system information files,
are relocated to a directory tree starting in the specified root_path.
-v version Specify the version of the package as version. The version is defined with the VERSION parameter in the pkginfo(4) file.
All compatible versions can be requested by preceding the version name with a tilde (~). Multiple white spaces are replaced
with a single white space during version comparison.
-x Designate an extracted listing of package information. The listing contains the package abbreviation, package name, package
architecture (if available) and package version (if available).
OPERANDS
pkginst A package designation by its instance. An instance can be the package abbreviation or a specific instance (for example,
inst.1 or inst.2). All instances of a package can be requested by inst.*. The asterisk character (*) is a special character
to some shells and may need to be escaped. In the C-Shell, "*" must be surrounded by single quotes (') or preceded by a
backslash ().
EXIT STATUS
0 Successful completion.
>0 An error occurred.
