utility
A program that can be called by name from a shell to perform a
specific task, or related set of tasks. This program is either an
executable file, such as might be produced by a compiler or linker
system from computer source code, or a file of shell source code,
directly interpreted by the shell. The program may have been produced
by the user, provided by the system implementor, or acquired from
an independent distributor. The term utility does not apply to the
special built-in utilities provided as part of the XSI Shell Command
Language; see the XCU specification, Special Built-in Utilities . The
system may implement certain utilities as shell functions (see the XCU
specification, Function Definition Command ) or built-in utilities,
but only an application that is aware of the command search order
described in the XCU specification, Command Search and Execution
or of performance characteristics can discern differences between
the behaviour of such a function or built-in utility and that of a
true executable file.
