Starting an application on X by console

tiagomadeira · 01-08-2005, 06:59 PM

Hey...

I did a program (my automatic e-mail verify) and I'm running it in console (starting in rc.local):

Code:

#!/bin/sh
        while : ; do
                if fetchmail -a --fetchmailrc /etc/fetchmailrc 2> /dev/null | grep flushed > /dev/null
                then
                        play /home/tiago/bin/notify.wav &
                        chown tiago.users /home/tiago/Mail/inbox/new/* &
                        chmod 777 /home/tiago/Mail/inbox/new/* &
                        su 'tiago' -c graphic-dialog.sh # THIS IS THE POINT
                fi
        done

graphic-dialog.sh

Code:

#!/bin/bash
if [ -z "$DISPLAY" ]; then
        dialog=dialog
else
        dialog=kdialog
fi
$dialog --yesno "`date`\nYou got `ls /home/tiago/Mail/inbox/new/ | wc -l` new mail(s).\n\nWant to open mutt?"

if [ $? = 0 ]; then
                aterm +sb -T "Mutt for Tiago Madeira" -fn nada -e mutt
        fi
fi

I'm using KDE (and DISPLAY=:0). The graphics programs (kdialog, aterm) doesn't work because I'm not connecting X. When I receive a mail it just play the sound.

How I do that?

PS: tiago <- my user
root <- who runs the program

Thanks...

I'm not sure but my guess is you need to add local users to x. The command is something like "xhost +local:". This will get X to accept connections from local users.

Thanks! Now it's working...

~/.kde/Autostart/xhost.sh

Code:

xhost +local:

~/bin/up_fetchmail.sh

Code:

#!/bin/sh
        while : ; do
                if fetchmail -a --fetchmailrc /etc/fetchmailrc 2> /dev/null | grep flushed > /dev/null
                then
                        play /home/tiago/bin/notify.wav &
                        chown tiago.users /home/tiago/Mail/inbox/new/* &
                        chmod 777 /home/tiago/Mail/inbox/new/* &
                        su tiago -c /home/tiago/bin/dialogo-mutt.sh
                fi
        done

~/bin/dialogo-mutt.sh

Code:

#!/bin/bash
if [ -z "$DISPLAY" ]; then
        dialog=/bin/dialog
else
        dialog=/opt/kde/bin/kdialog
fi
$dialog --yesno "`date`\nVocê tem `ls /home/tiago/Mail/inbox/new/ | wc -l` novo(s) e-mail(s).\n\nDeseja abrir o Mutt?" 0 0

if [ $? = 0 ]; then
        if [ "$dialog" = "/bin/dialog" ]; then
                mutt
        else
                aterm +sb -T "Mutt for Tiago Madeira" -fn nada -e mutt
        fi
fi

Now I got only another problem... if I'm not in graphic mode, I want that /bin/dialog does the dialogs (line 2-4, dialogo-mutt.sh) and mutt opens without terminal (line 10-12, dialogo-mutt.sh). Can I do that?

Thanks...

Ooops... It continues not working. I did the test with up_fetchmail running on KDE and it worked, but I rebooted and it's not working.

Some idea?

Thanks...

Yeah! Now it's working. I put a "export DISPLAY=":0"" in the start of my dialogo-mutt.sh. The problem was because only for user tiago the var DISPLAY had the right value.

Thanks for all and if somebody can help me now with openning non-graphic dialog in my user's console, it will be great.
