<div class="mw-translate-fuzzy"> | |||
Puedes usar '''KRunner''' para matar aplicaciones también. Escribe en el teclado <code>kill</code> seguido del nombre del proceso y '''KRunner''' mostrará varias opciones para cerrar la aplicación (SIGTERM) o matarla forzosamente (SIGKILL). '''KRunner''' buscará nombres de procesos parciales (a partir de tres caracteres) para ejecutar los procesos. | |||
</div> | |||
Nota que el comando <code>kill</code> puede ser cambiado en el runner "Terminar aplicaciones" para avoler la confusión del comando kill el cual acepta las ID de los procesos. | |||
=== | ===Direct installation=== | ||
(builtin plugin: Software Center) | |||
In case that you look for an application that has not been installed yet, KRunner will suggest a set of applications that match your search. In specific, since KRunner has been integrated with Plasma Software Center, [[Special:myLanguage/Discover | Discover]], will present you a list of applications, enabling you to proceed to direct installation. | |||
===Problemas de los comandos=== | |||
(builtin plugin: Command Line) | |||
Además para los programas listados en el menú de las aplicaciones, '''KRunner''' puede se usado para ejecutar comandos de la consola, incluyendo lanzadores binarios. Observa que cuando introduces un comando, '''KRunner''' no acepta comandos parciales u ofrece un autocompletado de los comandos. | |||
En la ejecución de un comando aparece un icono de llave inglesa que permite elegir opciones adicionales. Puedes optar por ejecutar el comando en una ventana de terminal e iniciarlo allí (eso puede ser útil si el comando produce una salida de texto que usted desea leer), o ejecutar el programa como un usuario diferente (introduciendo el nombre de usuario y la contraseña de este usario). | |||

KRunner es un lanzador construido sobre el escritorio Plasma. Si bien su función básica es lanzar programas desde una especie de línea de comandos, sus funcionalidades pueden ser extendida por los llamados "runners" que ayudan al usuario a lograr hacer una gran cantidad de tareas.
Características
Lamentablemente esta lista está incompleta y solo se presentan algunos ejemplos básicos del uso de KRunner. Descubre mas haciendo click en el icono '?' en KRunner.
Iniciar y terminar aplicaciones
(builtin plugin: Applications)
Puedes iniciar programas escribiendo simplemente el nombre de la aplicación que quieras abrir. Necesitas escribir como mínimo tres caractéres para empezar a buscar coincidencias. Las coincidencias serán encontradas en tu menú de aplicaciones.
You may type a single character and KRunner will start finding matches. Matches will be found to applications from your easily customizable applications menu (for that, right-click in menu).
Ejemplos:
Entrada | Salida |
gwe |
(starts Gwenview) |
Puedes usar KRunner para matar aplicaciones también. Escribe en el teclado kill
seguido del nombre del proceso y KRunner mostrará varias opciones para cerrar la aplicación (SIGTERM) o matarla forzosamente (SIGKILL). KRunner buscará nombres de procesos parciales (a partir de tres caracteres) para ejecutar los procesos.
Nota que el comando kill
puede ser cambiado en el runner "Terminar aplicaciones" para avoler la confusión del comando kill el cual acepta las ID de los procesos.
Direct installation
(builtin plugin: Software Center)
In case that you look for an application that has not been installed yet, KRunner will suggest a set of applications that match your search. In specific, since KRunner has been integrated with Plasma Software Center, Discover, will present you a list of applications, enabling you to proceed to direct installation.
Problemas de los comandos
(builtin plugin: Command Line)
Además para los programas listados en el menú de las aplicaciones, KRunner puede se usado para ejecutar comandos de la consola, incluyendo lanzadores binarios. Observa que cuando introduces un comando, KRunner no acepta comandos parciales u ofrece un autocompletado de los comandos.
En la ejecución de un comando aparece un icono de llave inglesa que permite elegir opciones adicionales. Puedes optar por ejecutar el comando en una ventana de terminal e iniciarlo allí (eso puede ser útil si el comando produce una salida de texto que usted desea leer), o ejecutar el programa como un usuario diferente (introduciendo el nombre de usuario y la contraseña de este usario).
Ejemplos:
Entrada | Salida |
ls ~/Documentos |
lista de contenidos de ~/Documentos (preferentemente un terminal) |
cp ~/Documentos/miArchivo ~/miArchivo |
copia miArchivo desde ~/Documentos a ~/ |
mplayer miVídeo.mkv |
reproduce miVídeo.mkv en mplayer |
De paso, si la línea de comandos es lo tuyo, podrías apreciar la integración con las páginas de ayuda (man). Simplemente escribe un comando precedido por #
para abrir la página de ayuda en formato web para una fácil lectura desde tu navegador.
Ejemplos:
Entrada | Salida |
#ls |
abre el manual para ls en un navegador |
Buscar páginas web
(builtin plugins: Bookmarks, Locations, Web Search Keywords)
Usted puede simplemente comenzar escribiendo la URL del sitio web que desea abrir en su navegador predeterminado. Puede incluso escribir el nombre de un marcador de Konqueror y KRunner lo abrirá para ti. Si has visitado una página web en el pasado, KRunner también puede buscar los resultados desde el historial de tu navegador.
Ejemplos:
Entrada | Salida |
miMarcador |
abre el marcador en un navegador |
kde.org |
abre la página de inicio de KDE en un navegador |
http://userbase.kde.org/ |
abre Userbase en un navegador |
KRunner conoce los atajos de teclado de Konqueror, por lo que puedes utilizarlos directamente.
Ejemplos:
Entrada | Salida |
gg:KDE |
busca en Google KDE |
wp:krunner |
busca en Wikipedia krunner |
KRunner además ofrece opciones para descargar archivos desde una web utilizando KGet escribiendo la URL.
Existen runners adicionales para una búsqueda rápida en Wikipedia, Wikitravel y KDE Techbase.
Abrir archivos, carpetas y dispositivos
(builtin plugin: Locations)
KRunner puede además abrir archivos y directorias en tu equipo local. Si desea buscar equipos remotos, puedes hacerlo también. Prestad atención como KRunner usa kioslaves para ssh (fish:) y samba (smb:).
Ejemplos:
Entrada | Salida |
file:/home/ |
opens file:///home/ (el directorio Home) en Dolphin |
file:miVídeo.mkv |
abre /home/miVídeo.mkv |
fish:you@server.com |
abre fish:/you@server.com/ vía fish (archivo sobre protocolo ssh) |
smb:miCarpetadeWindows |
abre smb:/miCarpetadeWindows vía Samba |
If you don't know the path to a file, simply type the name of the file. If the file is a recently opened document, KRunner will list it for you. If you have enabled "File Search" provided by Baloo daemon, you can also search your computer for the file by its indexed contents. KRunner will also open folders you've bookmarked in Dolphin (in your Places sidebar) if you type their name in. What's more, if you want to access devices on your system (both mounted and unmounted), you can do that, too. KRunner will even provide device-specific options.
Examples:
Input | Output |
Home |
opens the Home directory in Dolphin |
myFlashDrive |
shows options to mount or open the contents of myFlashDrive |
Multitask with sessions, windows, desktops and activities
Several KDE applications allow you to save and load sessions. KRunner allows you to launch these sessions. You can either type in the name of the application or directly type in the name of the session. Runners exist for opening sessions saved in Kate, Konqueror, Konsole, etc.
KRunner is a multitasker's dream. If you have too many windows open, just type in the title of the window and switch directly to it. You can similarly type in the name of a virtual desktop and switch directly to it. If you roll with activities, switch activities by typing their name in. KRunner will find a match as soon as you type three characters in.
KRunner will even switch desktop sessions for you. Type in the keyword switch
or new session
to start a separate X session. You can switch back and forth between sessions by using the switch
keyword.
Examples:
Input | Output |
Desktop 1 |
switches the virtual desktop to Desktop 1 |
myWorkActivity |
switches the activity to myWorkActivity |
switch |
shows options to switch to an existing session or start a new one |
new session |
starts a new session |
Several plasma widgets can be launched as windowed applications. You can simply type the name of a widget and KRunner will launch a window for you.
Talk to people
Type in the name of a contact in your KAddressBook to get a list of options to contact them. Typing in an email address into KRunner will open a KMail composer window. You can also search through contacts in your Kopete contact list.
The addressbook and kopete runners don't seem to be working in SC 4.8.
Examples:
Input | Output |
kde@mail.kde.org |
compose a mail to the KDE mailing list |
myContact |
show options to contact myContact |
Listen to some music
You can control any modern audio player such as Amarok using KRunner. You can use several keywords (all configurable) to play
, pause
or skip songs. Typing in the name of an artist, album or song that is in Amarok's library will let you either play immediately, play next (queue
) or play at the end (append
) of the current playlist. You can use keywords to increase
or decrease
the volume of the player, or even to mute
or quit
it.
Examples:
Input | Output |
play song search |
plays a song immediately |
pause |
pauses Amarok or your designated music player |
next |
plays next song in playlist |
Be on time
You can get the current date or time by typing in the keywords date
or time
. Selecting the result will copy it to your clipboard so you can paste it elsewhere. The format of the date and time respects your system settings.
Examples:
Input | Output |
date |
Today's date is ... |
time |
The current time is ... |
You can even get the date and time at another location by specifying the time zone or the city listed in the TZ database.
Examples:
Input | Output |
time UTC |
The current time in UTC is ... |
time oslo |
The current time in Europe/Oslo is ... |
time kolkata |
The current time in Asia/Kolkata is ... |
There is a runner for interfacing with Korganizer and fetching events, but it doesn't seem to be working in SC 4.8.
Calculator
KRunner features a very versatile calculator that can be called by starting or ending a calculation with an =
sign. In addition to basic arithmetic, you can call scientific functions like sqrt()
, sin()
, log()
, etc. A list of the supported functions is here. Note that trigonometric functions like sin()
, cos()
, etc expect the angle in radians. KRunner understands pi
in expressions.
Examples:
Input | Output |
32*12 = |
384 |
= sqrt(4) + 32*sin(30*pi/180) |
18 |
KRunner also supports combinatorics functions, like perm()
or comb()
.
Examples:
Input | Output |
= perm(10,5) |
30240 |
= comb(10,5) |
252 |
KRunner can also handle symbolic mathematics and perform integration and differentiation on expressions
Examples:
Input | Output |
= integrate( -x/y^2, y ) |
-x/y |
diff( log(x) ) = |
1/x |
You can also use KRunner to solve polynomial functions to find its roots.
Examples:
Input | Output |
= solve( x^2 + 4*x - 21 = 0 ) |
[3, -7] |
KRunner intelligently handles units as part of the calculations. Try the following examples to see how.
Examples:
Input | Output |
= 2.5 kg * 10 m/s^2 |
25 N |
220 V / 10 A = |
22 ohms |
Since KRunner understands most units, you can use it to convert them very quickly. Note that unit conversions don't require an =
sign.
Examples:
Input | Output |
30 F |
-1.11111 degrees C (°C), 273.039 K, ... |
27.8 km |
1.09449e+06 inches (in), 17.2742 miles (mi), ... |
5 gallons in liters |
18.9271 liters (l) |
KRunner knows currencies, too. Conversions between currencies is done by fetching the exchange rate from the European Central Bank website.
Examples:
Input | Output |
1 dollar |
0.657002 pounds sterling (GBP), 0.742501 euros (EUR), ... |
125 euros |
110.606 pounds sterling (GBP), 15,785 yen (JPY), ... |
30 JPY in RUB |
9.40731 rubles (RUB) |
Go places
If you have bookmarked locations in the Marble (in OpenStreetMap), KRunner can open the map directly.
Spell checking and special characters
KRunner can tell you whether your spelling is correct and/or suggest corrections. The default keyword to start the spellchecker is spell
and can be configured.
Examples:
Input | Output |
spell linux |
Suggested words: Linux, lynx, ... |
KRunner can also allow you to pick special characters if you can specify the hexadecimal unicode for the character, preceded by a #
sign.
Examples:
Input | Output |
#03b2 |
β |
#00b1 |
± |
Manage your computer
You can directly open system settings control modules from KRunner. Often, if you want to change something, just type associated terms and KRunner will find the control module with the settings you want.
Examples:
Input | Output |
keyboard |
opens the Keyboard settings control module |
fonts |
opens the fonts settings control module |
password |
opens the Password & User account control module |
KRunner can also be used to adjust the screen brightness by using the keywords "screen brightness". You can specify a percentage or just turn the brightness halfway or fully down. Additionally, keywords exist to suspend, logout, shutdown or restart your machine.
Examples:
Input | Output |
screen brightness 100 |
increases screen brightness to 100% |
sleep |
suspends computer to RAM |
lock |
locks the screen |
restart |
restarts computer |
shutdown |
shutdowns computer |
Usage
Open KRunner
The easiest way to open KRunner is to trigger its global shortcut (Alt+Space or Alt+F2, by default). In some activities (e.g. Desktop), you can simply click on the desktop and start typing. In others (e.g. Search and Launch), KRunner may be built into the activity itself.
You can also right-click on your plasma workspace and select krunner
.
Use KRunner
Use Tab/Ctrl+j or Shift+Tab/Ctrl+k to navigate up and down results. Use arrow keys to move between options (if any) in a result. Use Enter (or left click) to select a result.
Discover KRunner
Click on the wrench icon to bring up configuration options where you can enable/disable/configure runners that will process your searches. Additional options are available to change the position on the screen where krunner appears. You can even change the style to a task-oriented interface, if you like.
