Arrow keys in Putty returning ^ [[A ^ [[D ^ [[B instead of moving the cursor

Question

Has anyone else had this bug in PuTTy?

For example, pressing the Up key now produces:

>>> ^[[A 

Google does not allow you to search for special characters, so I cannot find an existing version of this problem.

EDIT:

So, this happened after I inserted it into some unicode (when, I think, the translation was already installed on utf-8).

I checked the "Change Settings" dialog box for different settings than other open PuTTy windows, but the settings look the same.

EDIT2:

This is fixed by restarting PuTTy, but still a nuisance.

EDIT3:

How to replicate the same error:

• Open putty terminal on Linux PC (I use RedHat)
• Open Python 2.7. * - using the python2.7 command (note: the error does not appear in version 2.6)
• import codecs
• Now use the arrow keys and these fancy characters appear.

Answer 1

In my experience, because "bash" doesn't work. Just run "/ bin / bash" to enjoy colors, history, etc.

Answer 2

You can try changing the "Cursor application keys" mode. It is located in the Terminal-> Keyboard section of the initial configuration window (these settings can be ported by your server).

Answer 3

For those who are interested in the problem, they had the same symptoms in a virtual environment, they solved the problem with

 pip install readlines 

See the following answer for more details.

Answer 4

Just run a simple bash command or sudo bash in ssh. This usually works.

Answer 5

I found that specifying "Function keys and keyboard" according to your operating system solves many problems.

Terminal → Keyboard → RadioButton "Linux"

(if you are using Linux) and then you can start a session
