Torch is an open source deep learning library for Lua. Varnish can execute Lua scripts in the request process by extending VCL through the Lua VMOD (Varnish module). [33] Vim has Lua scripting support starting with version 7.3. [34] VLC media player uses Lua to provide scripting support. Warframe uses Lua for HUD purposes and several other UI ...
In Linux, if the script was executed by a regular user, the shell would attempt to execute the command rm -rf / as a regular user, and the command would fail. However, if the script was executed by the root user, then the command would likely succeed and the filesystem would be erased. It is recommended to use sudo on a per-command basis instead.
A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. [1] The various dialects of shell scripts are considered to be command languages . Typical operations performed by shell scripts include file manipulation, program execution, and printing text.
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. [2]
The interpreter would execute one of a number of predefined commands, one of which would be to run a user program. Common commands would log the user on and off the system, allocate, free, and manipulate devices and files, and query various pieces of information about the system or a user process.
The execute permission only applies when the script is run directly. If a script is invoked as an argument to the interpreting shell, it will be executed regardless of whether the user holds the execute permission for that script. Although Windows also specifies an execute permission, none of the Windows-specific shells block script execution ...
#! /usr/bin/env python3 – Execute with a Python interpreter, using the env program search path to find it #! /bin/false – Do nothing, but return a non-zero exit status, indicating failure. Used to prevent stand-alone execution of a script file intended for execution in a specific context, such as by the . command from sh/bash, source from ...
Almost any problem which occurs when running a Lua module will be reported as "Script error" during program execution, such as invalid data or a misspelled variable name in the Lua source code.
