## Introduction

### What is a terminal?

&konsole; is an X terminal emulator, often referred to as a terminal or a shell. It emulates a command line interface in a text only window.

&konsole; typically runs a command shell, an application that executes commands that you type. The shell the &konsole; runs depends on your account settings. Consult your operating system documentation to know what the shell is, how to configure it and how to use it.

### Scrollback

&konsole; uses the notion of scrollback to allow users to view previously displayed output. By default, scrollback is on and set to save 1000 lines of output in addition to what is currently displayed on the screen.

As lines of text scroll off the top of the screen, they can be reviewed by moving the scroll bar upwards, scrolling with a mouse wheel or through the use of the &Shift;Page Up (to move back), &Shift;Page Down (to move forward), &Shift;Up Arrow (to move up a line) and &Shift;Down Arrow (to move down a line) keys.

The amount of scrolling using &Shift;Page Up/Down can be switched between half and full page in the Scrolling tab of the profile configuration window (use Settings Edit Current Profile... to open this window).

### Profiles

Profiles allow the user to quickly and easily automate the running of common commands. Examples could include:

- ssh into another machine

- starting an irc session

- use tail to watch a file

All new and changed profiles are saved in the user's local home folder in `$`XDG_DATA_HOME`/konsole`.

Procedure to create a new profile:

1. Click on the menu entry Settings Manage Profiles...

2. Switch to the Profiles page.

3. Click on the button New Profile....

4. Fill in the first entry with a name. This is the name that will show in the menu, and will be the default label instead of Shell when you start a session of this type.

5. Enter a command just as you normally would if you opened a new shell and were going to issue that command. For our first example above, you might type ``ssh` administration`.

6. On the other tabs of the dialog, configure this session's appearance. You can configure a different font, color scheme, $`TERM` type and many other settings for each session.

7. Press the OK button. The new session is now available in the Manage Profiles... dialog.

Any profiles which have Show in Menu checked will be listed by their name in the File New Tab menu. There will be no submenu if only the default profile is to be shown.

### Mouse Buttons

This section details the use of the mouse buttons for the common right handed mouse button order. For the left handed mouse button order, swap left and right in the text below.

Left

  All &LMB; clicks will be sent to a mouse-aware application running in &konsole;. If an application will react on mouse clicks, &konsole; indicates this by showing an arrow cursor. If not, an I-beam (bar) cursor is shown.

  Holding the &LMB; down and dragging the mouse over the screen with a mouse-unaware application running will mark a region of the text. While dragging the mouse, the marked text is displayed in reversed color for visual feedback. Select Copy from the Edit menu to copy the marked text to the clipboard for further use within &konsole; or another application. The selected text can also be dragged and dropped into compatible applications. Hold the &Ctrl; key and drag the selected text to the desired location.

  Normally, new-line characters are inserted at the end of each line selected. This is best for cut and paste of source code, or the output of a particular command. For ordinary text, the line breaks are often not important. One might prefer, however, for the text to be a stream of characters that will be automatically re-formatted when pasted into another application. To select in text-stream mode, hold down the &Ctrl; key while selecting normally.

  Pressing the &Ctrl; and &Alt; keys along with the &LMB; will select text in columns.

  Double-click with the &LMB; to select a word; triple-click to select an entire line.

  If the upper or lower edge of the text area is touched while marking, &konsole; scrolls up or down, eventually exposing text within the history buffer. The scrolling stops when the mouse stops moving.

  After the mouse is released, &konsole; attempts to keep the text in the clipboard visible by holding the marked area reversed. The marked area reverts back to normal as soon as the contents of the clipboard change, the text within the marked area is altered or the &LMB; is clicked.

  To mark text in a mouse-aware application (Midnight Commander, for example) the &Shift; key has to be pressed when clicking.

Middle

  Pressing the &MMB; pastes text currently in the clipboard. Holding down the &Ctrl; key as you press the &MMB; pastes the text and appends a new-line. That is convenient for executing pasted command quickly, but it can be dangerous so use it with caution.

  If you have a mouse with only two buttons, pressing both the &LMB; and &RMB; together emulates the &MMB; of a three button mouse.

  If you have a wheel as the middle button, rolling it in a mouse-unaware program will move &konsole;'s scrollbar.

Right

  These items appear in the menu when the &RMB; is pressed:

  - Copy

  - Paste

  - With a text selection a submenu Search for with a list of the preferred Web Shortcuts and an option to configure web shortcuts.

  - Open File Manager

  - Set Encoding

  - Clear Scrollback

  - Adjust Scrollback...

  - Show Menu Bar, only when the menubar is hidden

  - Switch Profile

  - Edit Current Profile...

  - Close Tab

  In a mouse aware application, press the &Shift; key along with the &RMB; to get the popup menu.

### Drag and Drop

If you drop a file, folder or &URL; on a &konsole; window, a context menu appears with these actions:

Drag and Drop Context Menu
Drag and Drop Context Menu

&Shift;Move Here

  Move the dropped item into the current folder. This item only appears in the context menu, if you have the rights to delete the dropped file or folder.

&Ctrl;Copy Here

  Copy the dropped item into the current folder.

&Ctrl;&Shift;Link Here

  Insert a symbolic link to the dropped item.

Paste Location

  Insert the full file path of the dropped item at the cursor.

Change Directory To

  If a folder is dropped, this action appears in the context menu and allows you to change the working folder of the &konsole; session.

&Esc;Cancel

  Break the drag and drop action.

If you press the shortcuts before releasing the &LMB; during drag and drop, no context menu appears and the actions will be executed immediately.

If you want to use the &Ctrl; key for drag and drop or disable the context menu to insert &URL;s as text by default, enable the corresponding options on the Mouse tab in the profile settings dialog.

## Command Reference

### The Menubar

The menubar is at the top of the &konsole; window. If the menubar is hidden, Show Menu Bar can be reached by right clicking in the window (as long as no full screen application is running in that window such as vi, minicom, etc.). The default shortcut is listed after each menu item.

It is also possible to configure the search case sensitivity, usage of the regular expression, highlighting all matches, and the search direction (Search backwards is the default). The General page is also the place where you can Enable all "Don't Ask Again" messages again if they were switched off before.

  - The Profiles page is meant for creating and handling profiles.

  - Using the Tab Bar/Splitters page you can configure the visibility and placement of tab bar, define tabs behavior and fine-tune the tab buttons options. It is possible to configure if you want to Show 'New Tab' button and Expand individual tab widths to full window or configure Use user-defined stylesheet. The Behavior tab can be used to define the place for the new tabs (At the end or After current tab) and closing of tabs with a &MMB; click.

    It is also possible to configure visibility of the split headers (When needed (default), Always, or Never) and define the drag handle size for splits (Small (default), Medium, or Large) using the Splits tab of this configuration page.

  - The Temporary Files page is used to define the scrollback file location.

  - The Thumbnails page can be used to define the thumbnail size and activation options (you can choose the activation control key from &Shift;, &Alt;, and &Ctrl;).

    To use the thumbnails feature showing image thumbnails in popups when hovering image items with the mouse pointer, you should enable file underlining for your current profile: Settings Edit Current Profile...Mouse Miscellaneous Underline files.

#### Help Menu

&konsole; has the some of the common &kde; Help menu items, for more information read the section about the Help Menu of the &kde; Fundamentals.

### &konsole; Dialogs

#### Configure Tab Settings Dialog

The name format, the remote tab title format, and the color of the current tab can be changed from this dialog. The dialog can be displayed via the menu, the shortcut &Ctrl;&Alt;S or by double-clicking on the tab in the tab bar. These changes are temporary and can be made permanent by editing the current profile.

&konsole; will substitute these tokens for local tabs:

- %n : program name

- %d : current directory (short)

- %D : current directory (long)

- %h : local host (short)

- %u : user name

- %B : user's Bourne prompt sigil ($ = normal user, # = superuser)

- %w : window title set by shell

- %# : session number

&konsole; will substitute these tokens for remote tabs:

- %c : current program

- %h : remote host (short)

- %H : remote host (long)

- %u : user name

- %U : user name@ (if given)

- %w : window title set by shell

- %# : session number

Examples:

- `%d : %n` with /usr/src as current directory and running bash will display src : bash

- `%D : %n` with /usr/src as current directory and running top will display /usr/src : top

- `%w (%#)` with ~ as current directory and running vim in the first tab will display [No Name] (~) - VIM(1)

#### Copy Input Dialog

The text entered in one tab can simultaneously be sent to other tabs. This dialog allows you to select which tabs will get that input. The current tab will be greyed out.

#### Adjust Scrollback Dialog

The scrollback options for the history size can be changed in this dialog. Any changes are for the current tab only and will not be saved to the profile.

## Command-line Options

When &konsole; is started from the command line, various options can be specified to modify its behavior.

`--help`

  List various options.

`--profile` `file`

  Start &konsole; using the specified profile instead of the default profile.

`--fallback-profile`

  Use the internal FALLBACK profile. This option is a shortcut for `--profile` `FALLBACK/`.

`--workdir` `dir`

  Open with `dir` as the initial working directory.

`--hold, --noclose`

  Do not close the initial session automatically when it ends.

`--new-tab`

  Create a new tab in an existing window rather than creating a new window.

`--tabs-from-file` `file`

  Create tabs as specified in the given tabs configuration file.

  The file has one tab per line in the following format:

  Each line specifies a tab to open using up to 4 fields specifying how it is to open. Fields are delimited with `;;` and a field name must have a `:` appended. Empty lines or lines with `#` at the beginning are ignored, so you can use line beginning with `#` to add comments.

  - `title:` a name for this tab, tab default if blank or not specified
  - `workdir:` working directory, `~` if blank or not specified
  - `profile:` a &konsole; profile to use, the default if blank or not specified
  - `command:` a command to run

  Each line should contain at least one of `command` or `profile` field.

  Example: `title: %n;; command: /usr/bin/top ;; profile: Shell`

`--background-mode`

  Start &konsole; in the background and bring to the front when &Ctrl;&Shift;F12 (by default) is pressed.

`--separate`
`--nofork`

  Run the new instance of &konsole; in a separate process.

`--show-menubar`

  Show the menubar, overriding the default behavior.

`--hide-menubar`

  Hide the menubar, overriding the default behavior.

`--show-tabbar`

  Show the tabbar, overriding the default behavior.

`--hide-tabbar`

  Hide the tabbar, overriding the default behavior.

`--fullscreen`

  Start &konsole; in fullscreen mode.

`--notransparency`

  Disable transparent backgrounds, even if the system supports them.

`--list-profiles`

  List all available profiles.

`--list-profile-properties`

  List all possible properties with name and type. See option `-p`.

  For more information, please visit &konsole; API Reference.

`-p` `property=value`

  Change the value of a profile property.

`-e` `command`

  Execute `command` instead of the normal shell.

  This option will catch all following arguments passed to &konsole;, and execute it as `command`. So this option should always be used as the last option.

&konsole; also accepts generic &Qt; and &kf5-full; options, see man pages qt5options and kf5options.

## Scripting &konsole;

&konsole; does support numerous methods that can be used with &DBus;.

There are two ways to use the &DBus; interface: &Qt;'s &GUI; qdbusviewer and the command line qdbus.

Examples:

- &percnt; `qdbus` will display all services available.

- &percnt; `qdbus` `org.kde.konsole` will display the &DBus; interface for &konsole;.

- &percnt; `qdbus` `org.kde.konsole /Windows/1` will display methods for controlling window 1.

- &percnt; `qdbus` `org.kde.konsole $KONSOLE_DBUS_WINDOW` will display methods for controlling the current window.

- &percnt; `qdbus` `org.kde.konsole /Sessions/1` will display methods for controlling session 1.

- &percnt; `qdbus` `org.kde.konsole $KONSOLE_DBUS_SESSION` will display methods for controlling the current session.

- &percnt; `qdbus` `$KONSOLE_DBUS_SERVICE $KONSOLE_DBUS_SESSION` will display methods for controlling the current &konsole;'s session.

If any of the above commands outputs: Service 'org.kde.konsole' does not exist, change `org.kde.konsole` to one of the following:

- `org.kde.konsole-`pidof -s konsole`` (will select first pid)

- `$KONSOLE_DBUS_SERVICE` (this can be used from the current &konsole;)

- `select one from the output of 'qdbus | grep konsole'`

For more information, please visit &DBus; tutorial.

## Terminal Key Bindings

### How &konsole; Uses Key Bindings

#### Introduction

&konsole; uses *.keytab files to translate key combinations into control characters and escape sequences that are sent to the shell or to interactive programs (typically programs that use the Alternate Screen buffer, &eg; vim, less, screen) running in the shell.

Users can customize the key bindings settings in &konsole; using the Key Bindings Editor. A key combination can be configured to send a specific control or escape sequence to the terminal.

You can open the Key Bindings Editor from the menu entry Settings Edit Current Profile, and going to the Keyboard tab. Listed there are the Key Bindings schemas that come by default with &konsole;.

#### Key Combinations and Modes

Key combinations follow the pattern:

    Key (+|-) Modes

for example:

    Up+Shift+AppScreen
    Down+Shift-AppScreen
    Space+Ctrl

Key names are defined in the qnamespace.h header file, with the Qt::Key_ prefix removed, for a list of key names check the Qt::Key enumeration in the &Qt; documentation.

A + preceding a Mode name means that mode is set; for a modifier key, that means it's pressed, whereas for all other modes it means that particular mode is in effect (&ie; active). For example +Ctrl means the key combination will work only if the &Ctrl; key is pressed.

A - preceding a Mode name means that mode is reset; basically this is the opposite of putting + before a Mode name, so for a modifier key that means the key isn't pressed, whereas for all other modes it means that particular mode is inactive. For example -Ctrl means the key combination will work only if the &Ctrl; key is not pressed.

If a Mode name isn't present in a key combination, its state is ignored.

The supported Key Bindings modes are listed below:

Alt, Ctrl, Shift

  One or more of these Modes can be used in a key combination, if any of them is set, the key combination uses that modifier key, respectively; and vice versa if it's reset

AnyModifier

  If this mode is set, the key combination uses any modifier key (any of the previous three modifier keys); and vice versa if it's reset

Ansi

  If this mode is set, &konsole; will send ANSI escape and control sequences

  If this mode is reset &konsole; will send VT52 escape and control sequences

AppScreen

  If this mode is set, the key combination will only affect interactive programs that use the Alternate Screen buffer

  If this mode is reset the key combination will only affect the terminal when it's using the Normal Screen buffer

  &konsole; makes use of two screen buffers:

  - The Normal Screen buffer (default): allows you to scroll back to view previous lines of output, this is the default buffer you usually use to execute commands... &etc;

  - The Alternate Screen buffer: the terminal switches to this buffer when you run an interactive program (&eg; less, vim, screen, tmux... &etc;)

KeyPad

  If this mode is set, the key combination uses a key on the Keypad (Number Pad). This mode is useful to distinguish between keys on the keyboard and keys on the Keypad. For example when Num Lock is on you can configure two separate key combinations, one using the key labelled 1 on the keyboard (usually under the F1 key) and the other using the key labelled 1 on the Keypad. The same concept applies when Num Lock is off for the End, Home, Cursor Keys ...etc on the Keypad

AppCursorKeys

  This mode implements the VT100 Cursor Keys Mode (DECCKM). It controls the escape sequences each Cursor Key (Up, Down, Right, Left) sends, depending on whether this mode is set or reset

  By default &konsole; follows the XTerm behavior of treating the Home and End keys as cursor keys with respect to DECCKM

AppKeyPad

  If this mode is set, the key combination will only work when the Keypad is in Application Mode (DECKPAM)

  If this mode is reset, the key combination will only work when the Keypad is in Numeric Mode (DECKPNM)

NewLine

  If this mode is set, the Return (Enter) key on the keyboard will send both Carriage Return "\r" and New Line "\n" control characters

  If this mode is reset, the Return key will send only a Carriage Return "\r"

  The same applies to the Enter key on the Keypad

  This mode emulates the LNM - Line Feed/New Line Mode

Note that each combination of Key and Modes (set/reset) must be unique. For example, consider the following two rules:

- A+Shift : A

- a : a

&konsole; will not accept the small letter a rule, you have to add a -Shift to that rule to make it work.

#### The Output Field

In the Output field you can add the escape sequences or control characters that you want &konsole; to send to the terminal when the associated key combination is pressed.

You can also use any of the following keywords, each of which has a special meaning in &konsole;:

- scrollUpLine : scroll up one line in the shell history scrollback buffer

- scrollUpPage : scroll up one page in the shell history scrollback buffer

- scrollDownLine : scroll down one line in the shell history scrollback buffer

- scrollDownPage : scroll down one page in the shell history scrollback buffer

- scrollUpToTop : scroll up to the begining of the shell history scrollback buffer

- scrollDownToBottom : scroll down to the end of the shell history scrollback buffer

You can also use strings with C-string syntax; you may use the following escapes sequences:

- \E : Escape

- \\ : Backslash

- \" : Double quote

- \t : Tab

- \r : Carriage Return

- \n : New line

- \b : Backspace

- \xHH : where HH are two hex digits

  This can be used to send &ASCII; control characters, &eg; \x00 which is the NUL character

#### Other System Resources

There are other system resources that can affect terminal Key Bindings:

- Consult the terminfo or termcap database for the expected escape sequences and control characters that each key combination is supposed to send.

- It is likely that your system has other keyboard databases which have to be in sync too, (&eg; /etc/inputrc and readline for the BASH shell) as they affect the operations (interactions) bound to key combinations.

#### Further Reading

For more information on escape sequences and control characters, check the following documentation:

- The VT100 user guide

- The VT102 user guide

- The comprehensive and indispensable XTerm Control Sequences documentation

## Using Style Sheet for the Tab Bar

The default style sheet for the tab bar sets the minimum and maximum tab widths. The user can create a `.css` file and have &konsole; use that as the style sheet for the tab bar. In the `.css` file, the widget to use is `QTabBar::tab`.

For more information, consider reading &Qt; Style Sheets

Examples:

- Change the selected tab's background to a light gray

      QTabBar::tab:selected {
          background: #999999
      }

- Change the selected tab's text to red

      QTabBar::tab:selected {
          color: red
      }

- All tabs will be at least 200 pixels in width

      QTabBar::tab {
          min-width: 200px
      }

- Only the selected tab will be at least 200 pixels in width

      QTabBar::tab::selected {
          min-width: 200px
      }

- Any of these can be combined in one file

      QTabBar::tab::selected {
          background: #999999;
          color: red;
          min-width: 200px;
      }
      QTabBar::tab {
          min-width: 100px
      }

## Did You Know?, Common Issues and More

### Did You Know?

- Pressing &Ctrl; while selecting text will cause lines breaks to be converted to spaces when pasted.

- Pressing the &Ctrl;&Alt; keys while selecting text will select columns.

- The &Ctrl;Wheel combination will zoom text size, like in konqueror and firefox.

- When a program evaluates either mouse button, pressing the &Shift; key will allow the popup menu to appear.

- The &Ctrl;&Shift;F10 shortcut will activate the menu.

- The &Shift;Insert keys will insert the clipboard.

- Double-clicking will select a whole word. Continuing to hold the mouse button and moving the mouse will extend the selection.

- Triple-clicking will select a whole line. Continuing to hold the mouse button and moving the mouse will extend the selection.

- There is a hidden feature for the "%d" formatter in tab title. You can tell &konsole; to abbreviate a directory name into its first character. For example, "/path/to/konsole/src" can be abbreviated into "konsole/s". If you want to enable and control this hidden feature, open `konsolerc` in ``qtpaths` `--paths GenericConfigLocation`` and add following lines:

      [ProcessInfo]
      CommonDirNames=name1,name2,name3...

  If you are using Yakuake, you need to edit `yakuakerc` in ``qtpaths` `--paths GenericConfigLocation`` instead.

### Common Issues

- Some fonts might be unavailable for usage in &konsole;, although they are available in other applications. That doesn't mean there is a bug in &konsole;. &konsole; requires monospaced fonts to provide the best visual result, so it asks &Qt; to only list monospaced fonts.

  Starting with version 16.08 (August 2016), &konsole; can be configured to allow selecting any font with the caveat that the display may not be correct.

- Since KDE4 all the tabs use the same process ID. This has the side-effect that if one tab's process has issues, all the other tabs may experience issues as well.

  This is most noticeable when a command that connects to an external device or system (ssh, nfs) has issues.

- &konsole; treats arguments after the `-e` option as one command and runs it directly, instead of parsing it and possibly dividing it into sub-commands for execution. This is different from xterm.

  - `konsole -e "command1 ; command2"` does not work

  - `konsole -e $SHELL -c "command1 ; command2"` works

- &konsole; doesn't provide convenience for running login shell, because developers don't like the idea of running login shell in a terminal emulator.

  Of course, users still can run login shell in &konsole; if they really need to. Edit the profile in use and modify its command to the form of starting a login shell explicitly, such as "`bash -l`" and "`zsh -l`".

- The `--new-tab` option sometimes behaves strangely. It may create new window, or it may create new tab in another existing &konsole; window instead of the current &konsole; window.

  Those behaviors feel strange, but they are not necessarily bugs. The `--new-tab` option tries to reuse existing &konsole; windows, but not all &konsole; windows are reusable. All &konsole; windows opened through &krunner; are reusable, while most &konsole; windows opened from command line are not.
