USE(1) User Commands USE(1)
NAME
use - Frontend to the Usepackage Environment Manager
SYNOPSIS
csh and derivatives:
source /usr/share/usepackage/use.csh
bourne shell and derivatives:
source /usr/share/usepackage/use.bsh
korn shell:
. /usr/share/usepackage/use.ksh
use [-vs] [-f file] package ...
use -l
DESCRIPTION
Usepackage is an environment management program. It is based on the principle of packages - collections of executables that share a common
set of necessary environment variables, such as PATH, MANPATH or LD_LIBRARY_PATH.
For each given package, use sources the appropriate environment information into the current shell. The environment information is speci-
fied in a configuration file, see usepackage(1).
OPTIONS
-v Output verbose information to the standard error stream.
-s Silence warnings for un-matched packages. This is useful in a shell rc script when a package is known not to be available on all
architectures that the shell is used on.
-f file
Specify an alternate initial configuration file.
-l List available packages and groups.
FILES
/usr/share/usepackage/usepackage.conf
The default configuration file.
/usr/share/usepackage/use.csh
Shell setup for csh and derivatives.
/usr/share/usepackage/use.bsh
Shell setup for bourne shell and derivatives.
/usr/share/usepackage/use.ksh
Shell setup for ksh.
/usr/bin/usepackage
The underlying Usepackage executable.
ENVIRONMENT
Other than the reading and re-definition of environment variables for package setup, use also uses the following environment variables for
user configuration:
PACKAGES_PATH Colon-separated path list giving the directories to search for configuration files. Shell-style tilde (~) user-directory
escapes are expanded.
HOME If present in the environment, this is used to provide the expansion for the tilde (~) user-directory.
SHELL If present in the environment, the last path component of this is used for shell matching (see SYNTAX) and detecting the
style of environment output that should be used, see usepackage(1).
