By default, when csh runs a command, the command inherits the csh's stdio file handles for stdin, stdout and stderr, which normally all point to the console window where the C shell is running. The i/o redirection operators allow the command to use a file instead for input or output.
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.
xterm is the standard terminal emulator for the X Window System. It allows users to run programs which require a command-line interface. If no particular program is specified, xterm runs the user's shell. An X display can show one or more user's xterm windows output at the same time.
tcsh added filename and command completion and command line editing concepts borrowed from the TENEX operating system, which is the source of the “t”. [7] Because it only added functionality and did not change what was there, tcsh remained backward compatible [ 8 ] with the original C shell.
In benchmarks, WSL 1's performance is often near native Linux Ubuntu, Debian, Intel Clear Linux or other Linux distributions. I/O is in some tests a bottleneck for WSL. [46] [47] [48] The redesigned WSL 2 backend is claimed by Microsoft to offer twenty-fold increases in speed on certain operations compared to that of WSL 1. [6]
COMMAND.COM, the original Microsoft command line processor introduced on MS-DOS as well as Windows 9x, in 32-bit versions of NT-based Windows via NTVDM; cmd.exe, successor of COMMAND.COM introduced on OS/2 and Windows NT systems, although COMMAND.COM is still available in virtual DOS machines on IA-32 versions of those operating systems also.
GNOME Terminal and VTE are both written in C. [10] VTE is a library (libvte) implementing a terminal emulator widget for GTK, and a minimal sample application (vte) using that. VTE is mainly used in gnome-terminal, but can also be used to embed a console/terminal in games, editors, IDEs, etc.
less is a terminal pager program on Unix, Windows, and Unix-like systems used to view (but not change) the contents of a text file one screen at a time. It is similar to more, but has the extended capability of allowing both forward and backward navigation through the file.
