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 "$0" "$@"
