In the case of command execution from WSL, once cursor is above INSERT command or even when the cursor doesn't appear, directly gets copied from clipboard so just copy the command that you want to type and place the cursor. This happens when you add or edit contents of a file within a corresponding path.
Example:
[ansadmin@DESKTOP-M6D3UNM myproject]$ vi ansible.cfg
Within this file, I was unable to type or edit, so I entered the below command in notepad, copied it and once I placed the cursor, the command was auto pasted from clipboard. I then saved using esc and by :wq!
[defaults]
inventory=./inventory
host_key_checking=False
Ctrl+Cafter opening the terminal? Does the prompt appear? – sourav c. Oct 20 '14 at 06:07
