Completion is generally requested by pressing the completion key (often the <style data-mw-deduplicate="TemplateStyles:r1249182868">.mw-parser-output .keyboard-key{border:1px solid #aaa;border-radius:0.2em;box-shadow:0.1em 0.1em 0.2em rgba(0,0,0,0.1);background-color:var(--background-color-neutral-subtle,#f8f9fa);background-image:linear-gradient(to bottom,var(--background-color-neutral,#eaecf0),var(--background-color-neutral-subtle,#f8f9fa),var(--background-color-neutral,#eaecf0));color:var(--color-base,#202122);padding:0.1em 0.3em;font-family:inherit;font-size:0.85em}</style><kbd class="keyboard-key nowrap">Tab ↹</kbd> key). Command name completion is the completion of the name of a command. In most shells, a command can be a program in the command path (usually <code>$PATH</code>), a builtin command, a function or alias. Path completion is the completion of the path to a file, relative or absolute. Wildcard completion is a generalization of path completion, where an expression matches any number of files, using any supported syntax for <a href="#String_processing_and_filename_matching">file matching</a>. Variable completion is the completion of the name of a variable name (<a href="/wiki/Environment_variable" title="Environment variable">environment variable</a> or shell variable). Bash, zsh, and fish have completion for all variable names. PowerShell has completions for environment variable names, shell variable names and — from within user-defined functions — parameter names. Command argument completion is the completion of a specific command's arguments. There are two types of arguments, <a href="/wiki/Named_parameter" title="Named parameter">named</a> and positional: Named arguments, often called options, are identified by their name or letter preceding a value, whereas positional arguments consist only of the value. Some shells allow completion of argument names, but few support completing values. Bash, zsh and fish offer parameter name completion through a definition external to the command, distributed in a separate completion definition file. For command parameter name/value completions, these shells assume path/filename completion if no completion is defined for the command. Completion can be set up to suggest completions by calling a shell function.<a href="#cite_note-61">[45]</a> The fish shell additionally supports parsing of <a href="/wiki/Man_page" title="Man page">man pages</a> to extract parameter information that can be used to improve completions/suggestions. 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 script files. Individual cmdlets can also define dynamic completion of argument values where the completion values are computed dynamically on the running system. <div class="mw-heading mw-heading3"><h3 id="Command_history">Command history</h3>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=5" title="Edit section: Command history">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Command_history" title="Command history">Command history</a></div> Users of a shell may find themselves typing something similar to what they have typed before. 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. Most modern shells support command history. Shells which support command history in general also support completion from history rather than just recalling commands from the history. In addition to the plain command text, PowerShell also records execution start- and end time and execution status in the command history. <div class="mw-heading mw-heading3"><h3 id="Mandatory_argument_prompt">Mandatory argument prompt</h3>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=6" title="Edit section: Mandatory argument prompt">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Further information: <a href="/wiki/Named_parameter#Optional_parameters" title="Named parameter">Named parameter § Optional parameters</a></div> Mandatory arguments/parameters are arguments/parameters which must be assigned a value upon invocation of the command, function or script file. A shell that can determine ahead of invocation that there are missing mandatory values, can assist the interactive user by prompting for those values instead of letting the command fail. Having the shell prompt for missing values will allow the author of a script, command or function to mark a parameter as mandatory instead of creating script code to either prompt for the missing values (after determining that it is being run interactively) or fail with a message. PowerShell allows commands, functions and scripts to define arguments/parameters as mandatory. The shell determines prior to invocation if there is any mandatory arguments/parameters which have not been bound, and will then prompt the user for the value(s) before actual invocation. <a href="#cite_note-ps-mandatoryparameter-62">[46]</a> <div class="mw-heading mw-heading3"><h3 id="Automatic_suggestions">Automatic suggestions</h3>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=7" title="Edit section: Automatic suggestions">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Autocomplete" title="Autocomplete">Autocomplete</a></div> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Powershell_Intellisense_example_for_the_Get-Process_cmdlet.gif" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/4f/Powershell_Intellisense_example_for_the_Get-Process_cmdlet.gif/440px-Powershell_Intellisense_example_for_the_Get-Process_cmdlet.gif" decoding="async" width="440" height="120" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/4/4f/Powershell_Intellisense_example_for_the_Get-Process_cmdlet.gif 1.5x" data-file-width="514" data-file-height="140" /></a><figcaption>Command-line completion in <a href="/wiki/PowerShell" title="PowerShell">PowerShell</a>.</figcaption></figure>Shells featuring automatic suggestions display optional command-line completions as the user types.

The concept had been realized as early as 1978<a href="#cite_note-66">[50]</a> in the release of <a href="/wiki/C_shell" title="C shell">the C shell</a> (csh). PowerShell allows multiple named stacks to be used. Locations (directories) can be pushed onto/popped from the current stack or a named stack. Any stack can become the current (default) stack. Unlike most other shells, PowerShell's location concept allow location stacks to hold file system locations as well as other location types like e.g. <a href="/wiki/Active_Directory" title="Active Directory">Active Directory</a> organizational units/groups, <a href="/wiki/Database_server" title="Database server">SQL Server</a> databases/tables/objects, <a href="/wiki/Internet_Information_Server" class="mw-redirect" title="Internet Information Server">Internet Information Server</a> applications/sites/virtual directories.

There are two approaches to this; the shell can either suggest probable corrections upon command invocation, or this can happen earlier as part of a completion or autosuggestion. The <a href="/wiki/Tcsh" title="Tcsh">tcsh</a> and <a href="/wiki/Zsh" class="mw-redirect" title="Zsh">zsh</a> shells feature optional spell checking/correction, upon command invocation. Fish does the autocorrection upon completion and autosuggestion. The feature is therefore not in the way when typing out the whole command and pressing enter, whereas extensive use of the tab and right-arrow keys makes the shell mostly case insensitive. The PSReadLine<a href="#cite_note-PSReadLine-45">[31]</a> PowerShell module (which is shipped with version 5.0) provides the option to specify a CommandValidationHandler ScriptBlock which runs before submitting the command. This allows for custom correcting of commonly mistyped commands, and verification before actually running the command. <div class="mw-heading mw-heading3"><h3 id="Progress_indicator">Progress indicator</h3>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=11" title="Edit section: Progress indicator">edit</a>]</div> A shell script (or job) can report progress of long running tasks to the interactive user. Unix/Linux systems may offer other tools support using progress indicators from scripts or as standalone-commands, such as the program "pv".<a href="#cite_note-68">[52]</a> These are not integrated features of the shells, however. PowerShell has a built-in command and API functions (to be used when authoring commands) for writing/updating a progress bar. Progress bar messages are sent separates from regular command output and the progress bar is always displayed at the ultimate interactive users console regardless of whether the progress messages originates from an interactive script, from a background job or from a remote session. <div class="mw-heading mw-heading3"><h3 id="Colored_directory_listings">Colored directory listings</h3>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=12" title="Edit section: Colored directory listings">edit</a>]</div> <a href="/wiki/JP_Software" class="mw-redirect" title="JP Software">JP Software</a> command-line processors provide user-configurable colorization of file and directory names in directory listings based on their file extension and/or attributes through an optionally defined <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">%COLORDIR%</code> environment variable.

href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=19" title="Edit section: Keystroke stacking">edit</a>]</div> In anticipation of what a given running application may accept as keyboard input, the user of the shell instructs the shell to generate a sequence of simulated keystrokes, which the application will interpret as a keyboard input from an interactive user. By sending keystroke sequences the user may be able to direct the application to perform actions that would be impossible to achieve through input redirection or would otherwise require an interactive user. For example, if an application acts on keystrokes, which cannot be redirected, distinguishes between normal and extended keys, flushes the queue before accepting new input on startup or under certain conditions, or because it does not read through standard input at all. Keystroke stacking typically also provides means to control the timing of simulated keys being sent or to delay new keys until the queue was flushed etc. It also allows to simulate keys which are not present on a keyboard (because the corresponding keys do not physically exist or because a different keyboard layout is being used) and therefore would be impossible to type by a user. <div class="mw-heading mw-heading2"><h2 id="Security_features">Security features</h2>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=20" title="Edit section: Security features">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"><table class="box-Importance_section plainlinks metadata ambox ambox-content" role="presentation"><tbody><tr><td class="mbox-image"><div class="mbox-image-div"><img alt="" src="//upload.wikimedia.org/wikipedia/en/thumb/b/b4/Ambox_important.svg/40px-Ambox_important.svg.png" decoding="async" width="40" height="40" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/en/thumb/b/b4/Ambox_important.svg/60px-Ambox_important.svg.png 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/b/b4/Ambox_important.svg/80px-Ambox_important.svg.png 2x" data-file-width="40" data-file-height="40" /></div></td><td class="mbox-text"><div class="mbox-text-span">This section may contain information not <a href="/wiki/Wikipedia:What_Wikipedia_is_not#Encyclopedic_content" title="Wikipedia:What Wikipedia is not">important or relevant</a> to the article's subject.

On Unix systems, the execute permission controls access to invoking the file as a program, and applies both to executables and scripts. As the permission is enforced in the <a href="/wiki/Loader_(computing)" title="Loader (computing)">program loader</a>, no obligation is needed from the invoking program, nor the invoked program, in enforcing the execute permission – this also goes for shells and other interpreter programs. The behaviour is mandated by the <a href="/wiki/C_POSIX_library" title="C POSIX library">POSIX C library</a> that is used for interfacing with the kernel. POSIX specifies that the <code>exec</code> family of functions shall fail with EACCESS (permission denied) if the file denies execution permission (see <code><a rel="nofollow" class="external text" href="https://pubs.opengroup.org/onlinepubs/9799919799/functions/execve.html">execve</a></code> – System Interfaces Reference, <a href="/wiki/Single_Unix_Specification" class="mw-redirect" title="Single Unix Specification">The Single UNIX Specification</a>, Version 4 from <a href="/wiki/The_Open_Group" title="The Open Group">The Open Group</a>). The execute permission only applies when the script is run directly. If a script is invoked as an argument to the interpreting shell, it will be executed regardless of whether the user holds the execute permission for that script. Although Windows also specifies an execute permission, none of the Windows-specific shells block script execution if the permission has not been granted. <div class="mw-heading mw-heading3"><h3 id="Restricted_shell_subset">Restricted shell subset</h3>[<a href="/w/index.php?title=Comparison_of_command_shells&action=edit&section=23" title="Edit section: Restricted shell subset">edit</a>]</div> Several shells can be started or be configured to start in a mode where only a limited set of commands and actions is available to the user. While not a security boundary (the command accessing a resource is blocked rather than the resource) this is nevertheless typically used to restrict users' actions before logging in. A restricted mode is part of the <a href="/wiki/POSIX" title="POSIX">POSIX</a> specification for shells, and most of the Linux/Unix shells support such a mode where several of the built-in commands are disabled and only external commands from a certain directory can be invoked.<a href="#cite_note-103">[75]</a><a href="#cite_note-104">[76]</a> PowerShell supports restricted modes through session configuration files or session configurations.

Scripts will usually be designed to exclusively include scripts from known safe locations; but in some instances, e.g. when offering the user a way to configure the environment or loading localized messages, the script may need to include other scripts/files.<a href="#cite_note-106">[78]</a> One way to address this risk is for the shell to offer a safe subset of commands which can be executed by an included script.
