Embedded Local Terminal
CLion has an embedded local terminal where you can use the command line mode without leaving the IDE. Depending on your platform, you can work with command prompt, Far, powershell, bash, and so on.
Configure the terminal
-
In the Settings/Preferences dialog (Ctrl+Alt+S), click Terminal under Tools.
On the Terminal page, you can configure the desired shell, the default name for new session tabs, and other options.
The following settings are inherited by the embedded local terminal from the IDE settings:
On the Keymap page, you can configure the copy (Ctrl+C) and paste (Ctrl+V) shortcuts.
On the editor's Appearance page, you can configure anti-aliasing and caret blinking. The setting Use block caret is not inherited in the terminal: its caret is always block.
-
Under the editor's Color Scheme settings, you can change the following options:
On the Console Fonts page: line spacing, and console fonts.
On the Console Colors page: console colors.
On the General page: selection foreground and background colors.
