This displays the standard output of the command lint program.c at the computer, and at the same time saves a copy of it in the file program.lint. If a file named program.lint already exists, it is deleted and replaced. Similarly, both the stdout and stderr output streams can be redirected to standard output and the program.lint using stream ...
PowerShell scripts (files suffixed by .ps1) PowerShell functions; Standalone executable programs; If a command is a standalone executable program, PowerShell launches it in a separate process; if it is a cmdlet, it executes in the PowerShell process. PowerShell provides an interactive command-line interface, where the commands can be

Standard output is a stream to which a program writes its output data. The program requests data transfer with the write operation. Not all programs generate output. For example, the file rename command (variously called mv, move, or ren) is silent on success. Unless redirected, standard output is inherited from the parent process.
In PowerShell, all types of commands (cmdlets, functions, script files) inherently expose data about the names, types and valid value ranges/lists for each argument. This metadata is used by PowerShell to automatically support argument name and value completion for built-in commands/functions, user-defined commands/functions as well as for ...
^c puts(x) and fputs(x, stdout) write unformatted text to stdout. ^d fputs(x, stderr) writes unformatted text to stderr ^e INPUT_UNIT, OUTPUT_UNIT, ERROR_UNIT are defined in the ISO_FORTRAN_ENV module.
Files may be copied to device files (e.g. copy letter.txt lpt1 sends the file to the printer on lpt1. copy letter.txt con would output to stdout, like the type command. Note that copy page1.txt+page2.txt book.txt will concatenate the files and output them as book.txt. Which is just like the cat command). It can also copy files between different ...
For example, the following Perl one-liner will reverse all the bytes in a file: perl -0777e 'print scalar reverse <>' filename While most Perl one-liners are imperative, Perl's support for anonymous functions, closures, map, filter (grep) and fold (List::Util::reduce) allows the creation of 'functional' one-liners.
