nxsh(1) Command-line interface nxsh(1) ________________________________________________________________________________ NAME nxsh - Simple shell containing NSF/NX interpreter SYNOPSIS nxsh ?-c ?arg1?? ?arg2 ...? ________________________________________________________________________________ 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 com- mands from standard input interactively and prints command results as well as error messages to standard output. It remains active un- til 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 stan- dard input (e.g., in a pipe). nxsh can be used like tclsh to make NX scripts directly invocable 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 "$0" "$@" COPYRIGHT Copyright (c) 2014-16 Stefan Sobernig <stefan.sobernig@wu.ac.at>, Gustaf Neumann <gustaf.neumann@wu.ac.at>; available under the Creative Commons Attribution 3.0 Austria license (CC BY 3.0 AT). nxsh 2.4.0 nxsh(1)
