The base of each is exec (execute), followed by one or more letters: e – An array of pointers to environment variables is explicitly passed to the new process image. l – Command-line arguments are passed individually (a list) to the function. p – Uses the PATH environment variable to find the file named in the file argument to be executed.
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.
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
When the child process calls exec(), all data in the original program is lost, and it is replaced with a running copy of the new program. This is known as overlaying . Although all data are replaced, the file descriptors that were open in the parent are closed only if the program has explicitly marked them close-on-exec .
A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
REXX scripts for CMS share the filetype EXEC with EXEC and EXEC2, and the first line of the script specifies the interpreter to be used. REXX scripts for MVS may [a] be recognized by the low level qualifier EXEC or may [b] be recognized by context and the first line. REXX scripts for OS/2 share the filename extension .cmd with other scripting ...
The C shell is a command processor which is typically run in a text window, allowing the user to type and execute commands. The C shell can also read commands from a file, called a script . Like all Unix shells, it supports filename wildcarding , piping , here documents , command substitution , variables and control structures for condition ...
The current process may wait for the child to terminate or may continue to execute concurrent computing. Creating a new subprocess requires enough memory in which both the child process and the current program can execute. There is a family of spawn functions in DOS, inherited by Microsoft Windows.
