Kubuntu Run Command Dialog (Alt+F2) - A Quick Guide
Kubuntu and the Command Line: A Quick Access Guide
Kubuntu Linux represents a distinct version of Ubuntu, distinguished by its utilization of the KDE desktop environment in place of Gnome. However, the KDE desktop environment can be readily installed on standard Ubuntu systems.
A highly efficient method for executing commands within either Ubuntu or Kubuntu is through the Alt+F2 shortcut key. This action invokes a dialog box designed for direct command input.
Utilizing the Run Command Dialog
Pressing Alt+F2 brings up a dialog where you can type commands, much like you would in a terminal window. The command will then be executed immediately.
The "Options" button within this dialog provides access to a range of additional functionalities and settings.
For example, consider the command 'ls -l':
By selecting the "Run in terminal window" checkbox, the command's output will be displayed directly within a terminal window. While this feature's functionality may vary on Ubuntu, it proves particularly beneficial within Kubuntu or KDE environments.
Initiate the command by either pressing Enter or clicking the "Run" button. The resulting output will then be presented as follows:
Command History and Preferences
This method is especially useful for swiftly obtaining the results of commands like ifconfig, where only the command's output is required.
A noteworthy aspect of the Run Command feature is its ability to retain settings for individual commands. For instance, after typing 'ls -l' and enabling the "run in terminal window" option, subsequent command entries will default to these settings:
However, re-entering 'ls -l' will automatically re-activate the previously selected checkbox:
Additional Options
Further options include the ability to execute commands under the identity of a different user and to adjust the command's priority. While commands requiring root privileges are typically prefixed with sudo or gksu, this feature offers utility when running commands as entirely different user accounts.
