While typing any commands one of my environment variables also gets printed.

[root@appdynamics home]# ls

ls

192.168.71.2  192.168.71.50  karti  lost+found  postgres

printf "33]0;%s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"

How can I solve it for all the commands it is getting printed?

Shell type:Bash

This is what the output of prompt command and prompt vars

[root@appdynamics home]#
echo $PROMPT_COMMAND
echo $PROMPT_COMMAND
printf "33]0 %s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"
printf "33]0;%s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"

[root@appdynamics home]# echo $promptvars



echo $promptvars



printf "33]0;%s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"

/etc/bashrc:

# are we an interactive shell?
if [ "$PS1" ]; then
if [ -z "$PROMPT_COMMAND" ]; then
case $TERM in
xterm*)
if [ -e /etc/sysconfig/bash-prompt-xterm ]; then
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm
else
PROMPT_COMMAND='printf "33]0;%s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"'
fi
;;

if [ -e /etc/sysconfig/bash-prompt-screen ]; then

fi
;;

[ -e /etc/sysconfig/bash-prompt-default ] && PROMPT_COMMAND=/etc/sysconfig/bash-prompt-default
;;

# Turn on checkwinsize

printf "33]0;%s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"

This comes when you use the command bash -v. To get rid of it give the exit command.

Evidently something is wrong in your prompt settings. Check your shell configuration file; that's .bashrc for bash, .kshrc for ksh, .zshrc for zsh (always in your home directory). It's also possible that the configuration is in some system-wide file like /etc/bash.bashrc or /etc/zshrc. It's also possible that the configuration is misplaced, e.g. in ~/.profile or ~/.bash_profile or /etc/profile.

What you're seeing as the prompt looks like a command that's meant to be executed by the shell to construct the prompt. Maybe this is bash and someone wrote PS1='printf …' meaning PROMPT_COMMAND='printf …'. But that's only one possibility among many. Check the configuration files to see how the PS1 variable is defined, and other shell-dependent settings, such as the PROMPT_COMMAND variable and the promptvars option in bash.

If you can't figure it out, post your shell configuration files. And be sure to say which shell you're using! If you don't tell us exactly what's in your configuration, we can only speculate.

Quite simply, you simply exit the current shell using multiple exits
