Tcl (Tool Command Language) is a dynamic programming/scripting language based on concepts of Lisp, C, and Unix shells. It can be used interactively, or by running scripts (programs) which can use a package system for structuring. [4] Many strings are also well-formed lists.
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.
env is a shell command for Unix and Unix-like operating systems.It is used to either print a list of environment variables or run another utility in an altered environment without having to modify the currently existing environment.
custom commands for a command shell; [11] smaller programs than those that are better implemented in a compiled language; [ 12 ] "wrapper" programs for executables, like a batch file that moves or manipulates files and does other things with the operating system before or after running an application like a word processor, spreadsheet, data ...
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.
Numba is used from Python, as a tool (enabled by adding a decorator to relevant Python code), a JIT compiler that translates a subset of Python and NumPy code into fast machine code. Pythran compiles a subset of Python 3 to C++ . [164] RPython can be compiled to C, and is used to build the PyPy interpreter of Python.
In computing, command substitution is a facility that allows a command to be run and its output to be pasted back on the command line as arguments to another command. Command substitution first appeared in the Bourne shell , [ 1 ] introduced with Version 7 Unix in 1979, and has remained a characteristic of all later Unix shells .
There are tools available that can extract the docstrings from Python code and generate documentation. Docstring documentation can also be accessed from the interpreter with the help() function, or from the shell with the pydoc command pydoc. The doctest standard module uses interactions copied from Python shell sessions into docstrings to ...
