Using Control Scripts
Execution of Other Commands by Control Scripts
Chapter 11396
Execution of Other Commands by Control
Scripts
Every command executed by a control script is a potential source of
failure because the command may not exist on the target system. Your
script can use any command conditionally, if it checks first for its
existence and executability, and if it does not fail when the command is
unavailable.
• If the target system(s) conform with the POSIX 1003.2 Shells and
Utilities standard, then the Execution Environment Utilities of this
standard will also be available.
• If a fileset has a prerequisite dependency on another product/fileset,
then most of the control scripts for the dependent fileset can use the
commands of the required product/fileset, if the
$ROOT_DIRECTORY is /. (All commands perform their tasks in
prerequisite order).
• Commands should be referenced relative to the path components
specified in the PATH variable. (See the discussion of PATH and the
SW_PATH environment variable above.)
