<p>Konsole is the kde terminal emulator, it can be used to run console shells.</p>
73
<p>The Bourne shell (sh) was one of the major shells used in early versions of the Unix operating system and became a de facto standard. Every Unix-like system has at least one shell compatible with the Bourne shell. The Bourne shell program name is sh and it is typically located in the Unix file system hierarchy at /bin/sh. The Bourne shell is usually used as fallback for Bash or another shell. The features of the Bourne shell are quite limited if compared to something like Bash.</p>
75
<p>Bash stands for "Bourne again shell", a bit of a play on words. For many Linux distribution Bash is the default shell. The Bash command syntax is a superset of the Bourne shell command syntax. Among the features of Bash are: command line editing, command history, the directory stack, the $RANDOM and $PPID variables, and POSIX command substitution syntax $(..)/ When used as an interactive command shell and pressing the tab key, Bash automatically uses command line completion to match partly typed program names, filenames and variable names. Bash syntax simplifies I/O redirection in ways that are not possible in the traditional Bourne shell. For example Bash can redirect standard output (stdout) and standard error (stderr) at the same time using the &> operator.</p>

78
<p>The Z shell (zsh) is a Unix shell that can be used as an interactive login shell and as a powerful command interpreter for shell scripting. Zsh can be thought of as an extended Bourne shell with a large number of improvements, including some features of bash, ksh, and tcsh. Among its features are: programmable command-line completion, sharing of command history among all running shells, spelling correction, theme-able prompts and it is fully customizable.
79
Attesting to the sheer size of this shell is the famous first sentence of the shell's manual page, which reads "Because zsh contains many features, the zsh manual has been split into a number of sections", and then goes on to list seventeen items.</p>
