@(#)pkg_add.1

pkg_add - a utility for installing software package distributions. pkg_add [options] "pkg-name [.. pkg-name]" The pkg_add command is used to extract packages that have been previously created with the pkg_create command.

The following command line options are supported.

-v Turns on verbose output. "Optional."

-I If an installation script exists for a given package, do not execute it. "Optional."

-n Don't actually install a package, just report the steps that would be taken if it was. "Optional."

-R Do not record the installation of a package. This means that you cannot deinstall it later, so only use this option if you know what you are doing! "Optional."

"-p " prefix Sets prefix as the directory in which to extract files from any packages which do not explicitly set theirs. "Optional."

pkg_add is fairly simple. It simply extracts the requested packages into the current working directory and then performs the following steps:

If the package contains a require file (see pkg_create ), then this is executed first with the flag .b INSTALL to see whether or not installation should continue (a non-zero exit status means no).

If an install script exists for the package, it is then executed as follows:

First, before installing files in the data set, the install script is called with the flags

<script> pkg-name PRE-INSTALL

Where pkg-name is the name of the package in question and PRE-INSTALL is a keyword denoting that this is the "pre installation" pass. Files are then copied from the packing list into their new homes, as expected, and the install script is then executed a second time with the flags

<script> pkg-name POST-INSTALL

This all allows you to write an install script that does "before and after" actions.

After installation is complete, a copy of the packing list, in addition to any deinstall script the package might have, is copied into /var/pkg/<pkg-name> for subsequent possible use by pkg-delete.

Sure to be some. pkg_create "(" 1 ")," pkg_info "(" 1 ")," pkg_delete "(" 1 ")," Jordan Hubbard
