Read other recent issues. There are many about this.

If you run clink update it should get some changes that compensate for CJK ambiguous width characters. This is a CJK problem, which happens depending on the combination of font and code page and terminal program and characters in the prompt.

It should make the problem go away. But after updating Clink and restarting Cmder, if it still occurs, then press Ctrl-X Ctrl-Z and read the diagnostic report and further steps it suggests.

Thanks for your reply @chrisant996 . I didn't use clink for my usecase.

I am using bash in cmder using this method. https://gist.github.com/nickautomatic/02ccb76292f7f8d9767e

Oh. 😞 Sorry, then you can either run chcp 65001 to use UTF8 and disable CJK code pages, or change the prompt character to an ASCII character instead of the lambda. There are some other issues with directions on how to do that.

@lawweiliang Not sure why you would want to run bash this way since it is supported natively with the Cmder - Full you say you are using. You could simply make the Cmder included task {bash::bash} your default task as shown below:

Also I do not believe you are using the config you think you are using because you would not have the λ in the prompt if you were.

Running bash according to the link provided is not using Cmder configuration at all. It is simply using ConEmu and external component distributed as a part of Cmder to run your external install of Git Bash. I am running the config detailed here below:

Notice the difference between mine, $ instead of λ, where yours has the λ:
