DESCRIPTION

       nxsh ?-c ?arg1?? ?arg2 ...?
              nxsh  is  a  shell-like  application  that  reads  NX  and Tcl commands from different sources and
              evaluates them.

              If invoked without any arguments, nxsh runs in read-eval-print mode (REPL, interactive) similar to
              tclsh. In this mode, it reads commands  from  standard  input  interactively  and  prints  command
              results  as well as error messages to standard output. It remains active until the exit command is
              invoked or until it reaches end-of-file on its standard input.

              If invoked with at least one positional argument arg1, nxsh runs a NX/Tcl script  sourced  from  a
              file identified by arg1 using source.

              Passing  the -c flag makes nxsh accept commands from the command line provided by arg1. If arg1 is
              omitted, nxsh takes commands from standard input (e.g., in a pipe).

              nxsh can be used like tclsh to make NX scripts directly invokable from the shell, by providing the
              following first line ("shebang") in the respective script:

                #! /usr/bin/env nxsh

              A (more portable) alternative is:

                #! /bin/sh
                # the next line restarts using nxsh \
                    exec nxsh "$0" "$@"
