When I open the Konsole terminal app and press the Up arrow key to see the commands that I have typed earlier that are saved in the history file, some commands which I did not type always appear. The commands are:
cd / export TERM=xterm clear
The commands are always repopulated in the .bash_history file every time I clear the bash_history file log out and then log in or restarting and opening the Konsole app. Uninstalling and Reinstalling Konsole app does not fix this problem. Below is a screenshot of the .bash_history file after clearing the file, uninstalling and reinstalling Konsole, rebooting and opening the Konsole app and not typed and executed any command.
