Any parameter to CHAIN can be used as a command name in the script, i.e. can come first before any arguments. An example would be RUNCOM SCRIPT LISTF combined with CHAIN CMD followed by CMD at the start of a following line. CMD will be substituted into LISTF which will list the files in the directory (like the Unix ls command).
The Multics shell includes a run command to run a command in an isolated environment. [1] The DEC TOPS-10 [2] and TOPS-20 [3] Command Processor included a RUN command for running executable programs. In the BASIC programming language, RUN is used to start program execution from direct mode, or to start an overlay program from a loader program.
a.out is a file format used in older versions of Unix-like computer operating systems for executables, object code, and, in later systems, shared libraries.This is an abbreviated form of "assembler output", the filename of the output of Ken Thompson's PDP-7 assembler. [1]
He "felt that commands should be usable as building blocks for writing more commands, just like subroutine libraries." [14] "There was a facility that would execute a bunch of commands stored in a file; it was called runcom for "run commands", and the file began to be called "a runcom". rc in Unix is a fossil from that usage." [15] [16] 1964 ()
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]
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
On these computers, users can access a Unix-like command-line interface by running the terminal emulator program called Terminal, which is found in the Utilities sub-folder of the Applications folder, or by remotely logging into the machine using ssh. Z shell is the default shell for macOS; Bash, tcsh, and the KornShell are also provided.
