This functions similarly to Bash's Ctrl+R history search, but is always on, giving the user continuous feedback while typing commands. Fish also includes feature-rich tab completion, with support for expanding file paths (with wildcards and brace expansion), environment variables, and command-specific completions.
A shell script can provide a convenient variation of a system command where special environment settings, command options, or post-processing apply automatically, but in a way that allows the new script to still act as a fully normal Unix command. One example would be to create a version of ls, the command to list files, giving it a shorter ...
A graphical interface similar to one from the late 1980s, which features a graphical window for a man page, a shaped window (oclock) as well as several iconified windows. . In the lower right we can see a terminal emulator running a Unix shell, in which the user can type commands as if they were sitting at a termin
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems.

PowerShell has completions for environment variable names, shell variable names and — from within user-defined functions — parameter names.

[8] In Windows PowerShell, pushd is a predefined command alias for the Push-Location cmdlet and popd is a predefined command alias for the Pop-Location cmdlet. Both serve basically the same purpose as the pushd and popd commands.
In computing, Bash (short for "Bourne Again SHell,") [6] is an interactive command interpreter and command programming language [7] developed for UNIX-like operating systems.. Created in 1989 [8] by Brian Fox for the GNU Project, [9] it is supported by the Free Software Foundation [10] and designed as a 100% [11] free alternative for the Bourne shell (sh) [12] and other proprietary Unix sh

The user can type more characters and press Tab ↹ again to see a new, narrowed-down list if the typed characters are still ambiguous, or else complete the command ...
