如何在Linux X会话的终端屏幕上禁用或删除关闭按钮

Question

如何在linux x-session的终端屏幕上禁用或删除关闭按钮。这是我用来运行应用程序的示例代码：

>>> df=pd.DataFrame()
>>> df['co1']=pd.date_range(start='08/01/18',periods=4)
>>> df.T
         0          1          2          3
co1 2018-08-01 2018-08-02 2018-08-03 2018-08-04

>>> df.T.to_csv('test.csv',mode='a',index=False,header=False)

这是主要代码：

#!/bin/bash
failsafe="xterm -ls -T Failsafe -geometry 80x24-0-0"
trap "exec $failsafe" EXIT SIGHUP SIGINT SIGPIPE SIGTERM SIGIO
set +e > /dev/null 2>&1
set +u > /dev/null 2>&1
set +o posix > /dev/null 2>&1
if type shopt > /dev/null 2>&1 ; then
shopt -s execfail
else
no_exit_on_failed_exec=1
fi
for script in /etc/X11/xinit/xinitrc.d/*; do
test -d $script && continue
test -x $script || continue
case "$script" in
.*) continue ;;
*.rpm*) continue ;;
*.swap) continue ;;
*.bak) continue ;;
*.orig) continue ;;
*~) continue ;;
esac
$script
done
