Brain cramp using zenity in script ??

wmcase · 12-03-2006, 12:52 PM

Hi;

I have obviously missed something.

I am using 'zenity --entry' in a script. I want to capture within my script the value that I have input in the zenity input screen/block.

How do I do that? Are they the same as Bash parameters?
I.E. Are they positional parameters or $? or $# or $*?

I have read the manual examples and ny google tutorials carefully and I can't see how this might be done.

For those interested my script is the following:

#! /bin/bash
# Open nautilus as root
# file name: RootBrowse
# zenity --info \
# --text="$?"

sudo -K
zenity --entry \
--title="Browse files as root" \
--text="Enter your _password:" \
--entry-text "" \
--hide-text | sudo -S nautilus --no-desktop --browser \
1> /dev/null 2> /dev/null

if [ "$?" != 0 ]; then
zenity --error --text="Sorry, wrong password"
exit 1
fi

# End

My problem is that this script runs fine from the gterminal command line, but always tells me I have a wrong password when run from a panel/desktop launcher or the nautilus-script right click menu.

But still, I would be happy just knowing how to capture the zenity input value.

All suggestions gratefully received.

I am using Fedora Core 6 and Gnome 2.16.0.

Hi.

In a small sample:

Code:

#!/bin/sh

# @(#) s2       Demonstrate capture of entered text.

VERSION=$( zenity --version )
echo " Zenity version is :$VERSION:"

NAME=$( zenity   --title  "Entry box for name" --entry --text \
"What is your name?" )

echo " Variable NAME is :$NAME:"

which follows the man page note for the second example:

Quote:

... The entered text is returned on standard output.

The example produces, after a name has been entered:

Code:

% ./s2
 Zenity version is :2.8.2:
 Variable NAME is :Bill Case:

Best wishes ... cheers, makyo

Thanks mayko;

Resolved with a big sigh of relief and a huge slap on the forehead. "Of course"

Quote:

NAME=$( zenity --title "Entry box for name" --entry --text \
"What is your name?" )

I wasn't writing the variable syntax properly and I know better.
