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 "$0" "$@"
