Using Control Scripts

Using Environment Variables

Chapter 11384

SW_ROOT_DIRECTORY

• Defines the root directory in which the session is operating, either “/”

or an alternate root directory. This variable tells control scripts the

root directory in which the products are installed. A script must use

this directory as a prefix to SW_LOCATION to locate the product’s

installed files.

All control scripts (except for the configure and unconfigure scripts)

can be executed during an install or remove task on an alternate

root. If the scripts reference any product files, each reference must

include the {SW_ROOT_DIRECTORY} in the file pathname.

The scripts may only need to perform actions when installing to

(removing from) the primary root directory (“/”). If so, then the

SW_ROOT_DIRECTORY can be used to cause a simple exit 0 when

the task is operating in an alternate root directory:

if test "${SW_ROOT_DIRECTORY}" != "/"

then

exit 0

SW_SESSION_OPTIONS

• Contains the pathname of a file containing the value of every option

for a particular command, including software and target selections.

This lets scripts retrieve any command options and values other than

the ones provided explicitly by other environment variables.

SW_SOFTWARE_SPEC

• Contains the fully qualified software specification of the current

product or fileset. The software specification allows the product or

fileset to be uniquely identified. (Fully qualified software specs

include the r=, a=, and v= version components even if they contain

empty strings. For installed software, l= must also be included.)
