Wrapper scripts often use this command to run a program (either directly or through an interpreter or virtual machine) after setting environment variables or other configuration. By using exec, the resources used by the shell program do not need to stay in use after the program is started. [2] The exec command can also perform a redirection.
In computing the Process Environment Block (abbreviated PEB) is a data structure in the Windows NT operating system family. It is an opaque data structure that is used by the operating system internally, most of whose fields are not intended for use by anything other than the operating system. [ 1 ]
In computing, start is a command of the IBM OS/2, [1] Microsoft Windows [2] and ReactOS [3] command-line interpreter cmd.exe [4] (and some versions of COMMAND.COM) to start programs or batch files or to open files or directories using the default program. start is not available as a standalone program. The underlying Win32 API is ShellExecute.
The Call command in COMMAND.COM only supports calling external batch files. File name parser extensions to the Set command are comparable with C shell. [further explanation needed] The Set command can perform expression evaluation. An expansion of the For command supports parsing files and arbitrary sets in addition to file names.
The Thread Information Block (TIB) or Thread Environment Block (TEB) is a data structure in Win32 on x86 that stores information about the currently running thread. It descended from, and is backward-compatible on 32-bit systems with, a similar structure in OS/2. [1] The TIB is officially undocumented for Windows 9x.
In computing, a programming language consists of a syntax plus an execution model.The execution model specifies the behavior of elements of the language. By applying the execution model, one can derive the behavior of a program that was written in terms of that programming language.
The command displays the process identifiers (PIDs) of processes using the specified files or file systems. In the default display mode, each PID is followed by a letter denoting the type of access: In the default display mode, each PID is followed by a letter denoting the type of access:
