PuTTY: How to change the bell style and settings


A terminal bell is a sort of notification produced by an SSH server when some things happen or appear, such as an error message or global announcement

By default, PuTTY will use the Windows system ding whenever it’s told to signal a bell. This can sometimes be annoying, especially if something’s triggering the bell repeatedly

To change the bell style and settings, first choose a saved session from the menu

1) Click Load

2) Then, go to Bell

3) First, you can set the style of the terminal bell

4) Let’s change ours to Visual bell, which will cause the window to flash instead of making a sound

You can also change it to None to disable the bell completely, force it to beep using the PC speaker, or choose a custom sound file to play

Next section. With the buttons above, you can make the taskbar and window title notify you if you receive a bell when the window is not in focus

Flashing will cause the taskbar to blink, whereas Steady will display a solid color

The bottom section allows you to disable the bell temporarily when over-used, as defined by the settings. The defaults here should work fine

5) Return to the Session panel

6) Be sure to Save your session, or else the settings won’t stick

Then, let’s test out the bell

7) Log in

One way to trigger a bell is by pressing Backspace at the beginning of a line

The window will flash momentarily to represent a bell signal

This tutorial is now complete. You now know how to change the bell style and settings in PuTTY

  • I need to disable the bell for about 50 sessions, is there a way to automate changing this setting on all of them?

    • Hello komrad,

      Not that I am aware of, no. You would need to manually change this in each PuTTY installation or session.
