Nautilus Scripts Not Working (Fedora 12)

[kwanbis]

I'm trying to write some nautilus scripts.

I have a file (script) called fileType, on the scripts folder, that shows when i right click over a file, on the context menu, but it does nothing.

#!/bin/sh
for arg
do
filetype=$(file "$arg")
  gdialog --title "File-Type Determinator" --msgbox "File $filetype" 200 200
done

Now, i tried gdialog on terminal, and i get a command not found.

So, i changed gdialog --title "File-Type Determinator" --msgbox "File $filetype" 200 200 to echo "File $filetype" but i see nothing.

To test, i added at the end of the script the command "peazip", and peazip starts, so the script is running, but the echo/gdialog lines are not working, any ideas?

Ok, i finally got my script to work. Almost.

#!/bin/sh
for arg
do
	pathName=`echo $NAUTILUS_SCRIPT_CURRENT_URI | sed -e 's|file:///|/|' -e 's|//|/|' -e 's|%20| |'`
	fileName="$arg"
	fullName=$pathName/$fileName
	fileNoExt=${fileName%.*}
	fullFolder=$pathName/$fileNoExt
	# zenity --info --title="Executing..." --text="/usr/local/share/PeaZip/res/7z/7z x -o$fullFolder $fullName" --width=200 --height=200
	/usr/local/share/PeaZip/res/7z/7z x -o"$fullFolder" "$fullName"
	zenity --info --title="DONE Executing" --text="/usr/local/share/PeaZip/res/7z/7z x -o$fullFolder $fullName" --width=200 --height=200
done

Now, the problem is that 7z, executes hidden! I don't see it, i thought it would open a terminal like screen. But nothing.

What can it be? Can it be related to me not being able to see "echo XXX" messages also?
