py2exe is a Python extension which converts Python scripts (.py) into Microsoft Windows executables (.exe). These executables can run on a system without Python installed. [3] It is the most common tool for doing so.
#!/bin/sh – Execute the file using the Bourne shell, or a compatible shell, assumed to be in the /bin directory #!/bin/bash – Execute the file using the Bash shell #!/usr/bin/pwsh – Execute the file using PowerShell #!/usr/bin/env python3 – Execute with a Python interpreter, using the env program search path to find it
A problem with that approach is that on different computer systems, the exact path may be different. By instead using env as in the example, the interpreter is searched for and located at the time the script is run (more precisely, env does a system call to execvp, which does the job of
The above script records to script.log all output of the exec command. However, some interactive programs (such as Python ) do not echo their standard input when run under the resulting shell, although they do when run under the script command, again due to the detection of a terminal.
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.
In computing, a script is a relatively short and simple set of instructions that typically automate an otherwise manual process. The act of writing a script is called scripting . A scripting language or script language is a programming language that is used for scripting.
Jinja, a Python-powered template engine, inspired by Django's template engine; Kid, simple template engine for XML-based vocabularies; Meson build system, a software tool for automating the building (compiling) of software; mod_python, an Apache module allowing direct integration of Python scripts with the Apache web server
PlayOnLinux is developed using a combination of Bash, Python and wxPython. The system provides wrapper shell scripts that specify the configuration of Wine needed in order to install and run a particular application.
