Overrides the TERM environment variable.

Displays the terminal reset string, which typically resets the terminal to its power on state.

Displays the terminal initialization string, which typically sets the terminal's rendering options, and other attributes to the default values.

Turns the terminal's cursor on or off.

Turns keyboard repeat on or off.

Sets Cursor Key Application Mode on or off. When on, ESC O A, ESC O B, etc. will be sent for the cursor keys instead of ESC [ A, ESC [ B, etc. See the "vi and Cursor-Keys" section of the Text-Terminal-HOWTO for how this can cause problems for vi users.

Turns automatic line-wrapping on or off.

Sets the terminal's rendering options to the default values.

Sets the foreground text color.

Sets the background text color.

Sets the color for underlined characters.

Sets the color for half-bright characters.

Inverts the screen colors. Foreground and background are swapped, as are underline and half-brightness.

Turns bold (extra bright) mode on or off. Except at a virtual console, −bold off turns off all attributes (bold, half-brightness, blink, reverse).

Turns dim (half-brightness) mode on or off (see −hbcolor). Except at a virtual console, −half−bright off turns off all attributes (bold, half-brightness, blink, reverse).

Turns blink mode on or off. Except at a virtual console, −blink off turns off all attributes (bold, half-brightness, blink, reverse).

Turns reverse video mode on or off. Except at a virtual console, −reverse off turns off all attributes (bold, half-brightness, blink, reverse).

Turns underline mode on or off (see −ulcolor).

Stores the terminal's current rendering options (foreground and background colors) as the values to be used at reset-to-default.

Clears the screen and "homes" the cursor, as clear(1).

Clears from the current cursor position to the end of the screen.

Sets tab stops at the given horizontal cursor positions, in the range 1-160. Without arguments, shows the current tab stop settings.

Clears tab stops from the given horizontal cursor positions, in the range 1-160. Without arguments, clears all tab stops.

Clears all tab stops, then sets a regular tab stop pattern, with one tab every specified number of positions. Without an argument, defaults to 8.

Sets the interval of inactivity, in minutes, after which the screen will be automatically blanked (using APM if available). Without an argument, gets the blank status (returns which vt was blanked or zero for unblanked vt).

The force option keeps screen blank even if a key is pressed.

The poke option unblank the screen.

Writes a snapshot of the given virtual console (with attributes) to the file specified in the −file option, overwriting its contents; the default is screen.dump. Without an argument, dumps the current virtual console. Overrides −append.

Like −dump, but appends to the snapshot file instead of overwriting it. Only works if no −dump options are given.

Sets the snapshot file name for any −dump or −append options on the same command line. If this option is not present, the default is screen.dump in the current directory.

Enables or disables the sending of kernel printk() messages to the console.

Sets the console logging level for kernel printk() messages. All messages strictly more important than this will be printed, so a logging level of 0 has the same effect as −msg on and a logging level of 8 will print all kernel messages. klogd(8) may be a more convenient interface to the logging of kernel messages.

Puts the monitor into VESA vsync suspend mode.

Puts the monitor into VESA hsync suspend mode.

Puts the monitor into VESA powerdown mode.

Turns off monitor VESA powersaving features.

Sets the VESA powerdown interval in minutes. Without an argument, defaults to 0 (disable powerdown). If the console is blanked or the monitor is in suspend mode, then the monitor will go into vsync suspend mode or powerdown mode respectively after this period of time has elapsed.

Sets the bell duration in milliseconds. Without an argument, defaults to 0.

Sets the bell frequency in Hz. Without an argument, defaults to 0.
