sde-chooser(1)                 DG/UX R4.11MU05                sde-chooser(1)


NAME
       sde-chooser - execute environment-sensitive tool

SYNOPSIS
       sde-chooser [-e sde-target] path [tool-args]

DESCRIPTION
       The action of a number of software development tools depends on the
       current software development environment [see sde(5)].  Such tools
       have different versions in each environment.  Sde-chooser finds and
       executes the correct version of such a tool.

       For example, when a command line such as ``as foo.s'' is executed, a
       small program named as in /usr/bin executes sde-chooser with the
       appropriate arguments.  Sde-chooser in turn executes the correct
       version of as.

       Sde-chooser is not normally invoked from a shell command line, but it
       can be with the following arguments:

       -e sde-target  Specifies a software development environment
                      explicitly.  If this option is not given, sde-chooser
                      uses the current software development environment [see
                      sde-target(1)].

       path           The path to the desired tool within an environment.
                      Path is given as an absolute path but it is
                      interpreted as being relative to
                      /usr/sde/<sde-target>.  For example, /usr/bin/as
                      invokes /usr/sde/<sde-target>/usr/bin/as, where
                      <sde-target> is a software development environment.

       tool-args      All remaining arguments to sde-chooser are passed to
                      the selected tool as the argv array.  The first of
                      these arguments, argv[0], should be the command name.

       For example, the command line

         sde-chooser -e m88kbcs /usr/bin/cc cc -V

       will invoke the COFF version of cc with the -V option.  The effect,
       in this example, is the same as issuing the command cc -V in the
       m88kbcs software development environment.
