This Unix tutorial is recommended for the slightly advanced user who has
a working knowledge of basic UNIX Shell operation either from viewing
VTC's Unix Shell Scripting Fundamentals Tutorial or from another source.
This course describes how to create programs using the syntax and features
of the UNIX Shell, focusing on the most popular-- the Bourne Shell. In
this eight-hour tutorial, author Mark Virtue will demonstrate techniques
that will be compatible with all brands of UNIX, including LINUX. The
shell is a command programming language that provides an interface to
the UNIX operating system. Its features include control-flow primitives,
parameter passing, variables and string substitution. Constructs such
as while, if then else, case and for are available. Two-way communication
is possible between the shell and commands. String-valued parameters,
typically file names or flags, may be passed to a command. A return code
is set by commands that may be used to determine control-flow, and the
standard output from a command may be used as shell input. Find out more
using our Unix Shell tutorials and online training courses.
This training course is designed for fast learning and covers all the
fundamental points of the application, all cds work on a mac or pc and
no application is needed.
