Clonning Linux desktop to Apple TV

mackowiakp · 01-18-2018, 03:32 AM

Below small script for cloning Linux desktop over network to Apple TV:

Code:

#!/bin/bash
if [ -f ~/tmp/apple ]
then
proc=`cat ~/tmp/apple`
kill -9 $proc 
rm -f ~/tmp/apple 2>/dev/null
kdialog --passivepopup "End of cloning to Apple TV" 5 2>/dev/null
else
choice="$(avahi-browse _airplay._tcp -ptr|grep IPv4|awk -F';' '{print $7}'|grep -v ^$|zenity --list --hide-header --title="Apple TV" --text="Choose Apple TV..." --column="IP adresses" 2>/dev/null)"
if [ -z "$choice" ] 
then
kdialog --passivepopup "Error - no Apple TV chosen" 5 2>/dev/null
exit
else
PASSWD="$(zenity --password --title="Enter password")"
if [ -z "$PASSWD" ]
then
java -jar ~/Pobrane/airplay.jar -h "$choice" -d >~/tmp/apple_wyn 2>&1 &
proc=$!
else
java -jar ~/Pobrane/airplay.jar -h "$choice" -a $PASSWD -d >~/tmp/apple_wyn 2>&1 &
proc=$!
fi
sleep 2
error=`ack -1 --match password ~/tmp/apple_wyn`
if [ ! -z "$error" ]
then
        kdialog --passivepopup "Wrong password" 5 2>/dev/null
        kill -9 $proc
        exit
fi
kdialog --passivepopup "Cloning desktop to Apple TV" 5 2>/dev/null
echo $proc > ~/tmp/apple
fi
fi

It works properly when I run it from console. But if I define lunch icon on desktop in KDE environment, it seams to not execute line:

Code:

error=`ack -1 --match password ~/tmp/apple_wyn`

Any idea what is the problem?

Maybe it doesn't like backticks (are they UTF-8 special chars?)
Did you try to replace with

Code:

error=$(ack -1 --match password ~/tmp/apple_wyn)

Hmm. It still works when I run it from console. From KDE desktop define icon = no. I use only English ASCII characters as a password. But for example if I run script from desktop icon and enter blank password (Apple TV has already password assigned)
the lines

Code:

error=`ack -1 --match password ~/tmp/apple_wyn`
if [ ! -z "$error" ]

seams to not work. I have to mention once more that running script for console, works properly.

I was simply suggesting that whatever interprets .desktop file might not like the backticks ` so why not try the bash $() syntax instead?

Also are sure that error comes from this line? I mean you see a Kdialog popup with "Wrong password" message?

Finally I got it working. But really dont know what is the difference in fuctionality.
So instead the lines:

Code:

error=`ack -1 --match password ~/tmp/apple_wyn`
if [ ! -z "$error" ]

I placed:

Code:

error=`tail ~/tmp/apple_wyn|grep password|wc -l`
if [ $error -ne "0" ]

Now it works both started from ASCII console and from custom defined icon on KDE desktop.
But

my bet is that ack behaves differently when started from the "desktop" than from a terminal.
Ubuntu seems to have various of such tools, that make it quite hard to predict what they will do. There are workarounds for those commands I think, to make them behave more similar.
