The second is the full-screen mode. In Windows XP and earlier, the full-screen console uses a hardware text mode and uploads a raster font to the video adapter. This is analogous to a text system console. This early full-screen mode only supports VGA-compatible text modes, giving it a maximum character resolution of 80 columns by 28 rows. [2]
Support for command history means that a user can recall a previous command into the command-line editor and edit it before issuing the potentially modified command. Shells that support completion may also be able to directly complete the command from the command history given a partial/initial part of the previous command.
The following example shows how command-line completion works in Bash. Other command line shells may perform slightly differently. First we type the first three letters of our command: fir Then we press Tab ↹ and because the only command in our system that starts with "fir" is "firefox", it will be completed to: firefox
Command-line shells provide a command-line interface (CLI) to the operating system, while graphical shells provide a graphical user interface (GUI).

Implementations of the Unix shell are also available as part of the POSIX sub-system, [39] Cygwin, MKS Toolkit, UWIN, Hamilton C shell and other software packages.

In computing, command substitution is a facility that allows a command to be run and its output to be pasted back on the command line as arguments to another command. Command substitution first appeared in the Bourne shell , [ 1 ] introduced with Version 7 Unix in 1979, and has remained a characteristic of all later Unix shells .
