How to make CONFIRMATION DIALOG

[kurci2]

Hi!
I have created some lounchers. Usually for autostarting more programs. I'm wondering if someone can help me with making a CONFIRMATION DIALOG. Like one witch appears when i wanna shut my machine down.
I want to put that script in my other scripts, so when someone starts it, the first thing appearing is the confirmation dialog...
I don't want any more accidentally opned programs.

thanks :KS

$ man zenity
if you want dialogs from the shell.

for more elaborate widgets you could use python and wxpython.

[linux18]

sudo apt-get dialog
man dialog

I don't need it, I always start the right program every time no matter what it is :)

i have focused on zenity.

i have created louncher:

zenity --question
sleep 1
gnome-screensaver-command -l
sleep 1
sudo s2disk

problem is ... when zanity shows dialog i can press YES or NO. But no matter witch i press the script runs...

[MadCow108]

please read the manpage:
man zenity


For example, zenity --question will return either 0 or 1, depending on whether the user pressed OK or Cancel.


the return value of the last command is also saved in the $? variable in bash



if zenity --question; then
echo "yes";
else
echo "no";
fi

zenity --question
echo "return value was $?"

You need to write a bash script. Maybe something like this (using a zenity list):

#!/usr/bin/env bash

CHOICE1=$(zenity --list \
--height=220 \
--title="List" \
--text="Options" \
--radiolist \
--column="" --column="Option" \
FALSE "Shutdown" \
FALSE "Restart" \
FALSE "Suspend" \
TRUE "Hibernate")

case $CHOICE1 in
"Shutdown")
echo "shutdown..."
sudo shutdown -h now
;;
"Restart")
echo "restart..."
sudo reboot
;;
"Suspend")
echo "suspend..."
gnome-screensaver-command -l
;;
"Hibernate")
echo "hibernate..."
sudo s2disk
;;
esac

It's called a launcher, not to make fun of you, lounch is something completely different:
