unrecognized command in my ec2 instance history.

I have these two unrecognized commands in my ec2 instance history. I am not sure who has executed these and what does it do.

1.builtin printf "\e[?1049l"

2.if [ "$_termius_integration_installed" = "" ]; then _termius_integration_installed="yes"; builtin printf "\e]4545;A\a"; _termius_encode() { builtin echo -n "$1" | command base64; }; _termius_get_trap() { builtin local -a terms; builtin eval "terms=( $(trap -p "${1:-DEBUG}") )"; builtin printf '%s' "${terms[2]:-}"; }; if [[ "$HISTCONTROL" =~ .(erasedups|ignoreboth|ignoredups). ]]; then _termius_history_verify=0; else _termius_history_verify=1; fi; _termius_original_PS1="$PS1"; _termius_custom_PS1=""; _termius_in_command_execution="1"; _termius_current_command=""; _termius_current_cwd() { builtin printf "\e]4545;SetCwd;%s\a" "$(_termius_encode "$PWD")"; }; _termius_prompt_begins() { builtin printf "\e]4545;ShellPromptBegins\a"; }; _termius_prompt_ends() { builtin printf "\e]4545;ShellPromptEnds\a"; }; _termius_wrap_prompt() { builtin printf "[$(_termius_prompt_begins)]%s[$(_termius_prompt_ends)]" "$1"; }; _termius_command_started() { builtin printf "\e]4545;CommandStarted;%s\a" "$(_termius_encode "$1")"; }; _termius_command_exited() { builtin printf "\e]4545;CommandExited;%s\a" "$1"; }; _termius_update_prompt() { if [ "$_termius_in_command_execution" = "1" ]; then if [[ "$_termius_custom_PS1" == "" || "$_termius_custom_PS1" != "$PS1" ]]; then _termius_original_PS1=$PS1; _termius_custom_PS1=$(_termius_wrap_prompt "$_termius_original_PS1"); PS1="$_termius_custom_PS1"; fi; _termius_in_command_execution="0"; fi; }; _termius_precmd() { if [ "$_termius_current_command" != "" ]; then _termius_command_exited "$_termius_status"; fi; _termius_current_cwd; _termius_current_command=""; _termius_update_prompt; }; _termius_preexec() { if [[ !
