In computing, redirection is a form of interprocess communication, and is a function common to most command-line interpreters, including the various Unix shells that can redirect standard streams to user-specified locations. The concept of redirection is quite old, dating back to the earliest operating systems (OS).
Unix shells use dup2 for input/output redirection. Along with pipe(), it is a tool on which Unix pipes rely. The following example uses pipe() and dup() in order to connect two separate processes (program1 and program2) using Unix pipes:
Windows Services for UNIX (SFU) is a discontinued software package produced by Microsoft which provided a Unix environment on Windows NT and some of its immediate successor operating-systems. SFU 1.0 and 2.0 used the MKS Toolkit ; starting with SFU 3.0, SFU included the Interix subsystem, [ 1 ] which was acquired by Microsoft in 1999 from US ...

FreeBSD uses 64-bit time_t for all 32-bit and 64-bit architectures except 32-bit i386, which uses signed 32-bit time_t instead. [23] The x32 ABI for Linux (which defines an environment for programs with 32-bit addresses but running the processor in 64-bit mode) uses a 64-bit time_t. Since it was a new environment, there was no need for special ...
Unix-based software packaging and build tools were available for installing or creating pre-build software packages. Starting with release 5.2 (Server 2003/R2) the following capabilities were added: [6] "Mixed mode" for linking Unix programs with Windows DLLs; 64-bit CPU support (in addition to 32-bit) Large file system support on 64-bit systems
It can also be used to port Unix software (which uses pthreads) with little or no modification to the Windows platform. [4] Pthreads4w version 3.0.0 [5] or later, released under the Apache Public License v2.0, is compatible with 64-bit or 32-bit Windows systems. Version 2.11.0, [6] released under the LGPLv3 license, is also 64-bit or 32-bit ...
As with Cygwin, MSYS2 supports path translation for non-MSYS2 software launched from it. For example one can use the command notepad++ /c/Users/John/file.txt to launch an editor that will open the file with the Windows path C:\Users\John\file.txt. [9] [8] MSYS2 and its bash environment is used by Git and GNU Octave for their official Windows ...
