How can I make radiolist dialog which content so many options what is the value of the variable?Quote:
echo "How many options?"
read=VAR
dialog --title "sdf" --backtitle "sdff" --radiolist "ffdsfsd" 15 60 5 "1" "first" on "2" "second" off "3" "third" off "4" "fourth" off etc..
I must explode dialog in loop and add options? or something like that?
I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
I have a problem to use echo to display the content of a variable.
This is what I do:
Code:
#!/bin/bash
USAGE="Usage: name [OPTIONS] [DIRECTORIES]"
echo $USAGE
When I run this little script I get the following output:
Usage: name [OPTIONS] R
So I think that [DI might be some sort of escape sequence. But I do not know how to unescape it. Does anyone have a hint for me?
my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
foo=+12.40
bar=${foo#+}
I have a program I am writing where I have a for loop and I want to make it substitute the variable twice like:
for ((i=0;i<5;i++)) do
echo $"$i"
done

View 6 Replies View RelatedI am using Fedora 12. I have the following problem, when i working with system-config-samba dialog:I add the new user on the server:as following:
Unix username: vova
Windows username:test
As described in Customisation Guide for Red Hat 9: "If the user has a different username on a Windows machine and will be logging into the Samba serverfrom the Windows machine, specify that Windows username in the Windows Username field."So i logged from the Windows machine not under test(Windows username) but under vova.And i logged in without the problem. However it seems that samba should check windows username=test (as have written in samba-config) and ask an password for different users. And additionally, if samba check the currect user in Windows itself and verify it with Unix user, what for we need write the Windows username in samba config? I don't understand
I've been using an old Fortigate-60 at home for the kids for some time but now the license is expired again. Are there any free or inexpensive alternatives? I'd like something I can run on a linux firewall and share against multiple users, with different profiles. In the past I ran squid and I whitelisted sites each kid was allowed to use but this becomes tedious as the kids get older and need access to more. I'd love something that could check a website rating or category list, let the user through for certain categories, and block bad or unrated sites. I don't really need virus checking or email scanning or the like.

how I can search within a variable and assign the results to a new variable. I'll use the following as an example -

A
C

What I'd like to get for output is -
Audi

View 8 Replies View RelatedIs there a way to make a dialog with zenity which would show an updating list? Zenity does it with progress, but I didn't figure out if it's possible to do it with the list. I.e. for example, I want to monitor something, and update the dialog with new list periodically. Is it even possible? zenity can wait for data from stdin, but it just adds stuff to the list. May be there are some control sequences which clear the list in the dialog?
For example:
{ echo "Foo"; sleep 2; echo "Bar"; } | zenity --list --title='Dynamic list?' --text='Some data' --column='values'
How can I instead of adding Bar, replace the Foo with it?

View 4 Replies View RelatedIs it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
I am envisioning a dialog menu with 2 sections, the top 2/3 a menu, then the bottom 1/3 is a message box. When you highlight a menu item it gives you a description of what it does in the message box. However I am not sure it is possible. Can this be done in BASH?
View 2 Replies View RelatedAnyway, here is something that is puzzling me and cannot think up a good way around it: I call the constructor and show elements of LoginDialog in the constructor of my QMainWindow, like this:
PHP Code:
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow){ ui->setupUi(this); LoginDialog *lid = new LoginDialog(this); lid.show();}
LoginDialog is a QDialog and it does show up on application start... but...
It is not active! The QMainWindow is the active window, even if I put lid->activateWindow();
So, the question is: how do I pop up this dialog on application start in such a way that it will show the LoginDialog on startup as active window?
I cannot seem to get if else statements to work. if $choice == Dog then i want it to say "you selected Dog" The variable choice has the value Dog in it as proved at the end by echo "yes $choice is $choice" following the error Code: ./test.sh: 37: [$choice: not found How do i get the conditional statement to work?

I want to display an un-intrusive graphical dialog to notify the workstation user that a bash script has finished running. It should be "top level", so visible to the user when it appears but should not grab focus, so the user can continue working in the current window and dismiss the notification when convenient. Researching gdialog, xdialog, xmessage and zenity it seems none of them can do this; they all grab focus.

Then I markd Inbox and All mail folders to be synced for offline usage from their properties (right-click folder and select Properties item).I tried File>Download Messages for Offline Usage and Send/Receive button and Work Offline / Work Online and pressing sync for offline usage when it asks before going offline.

View 1 Replies View RelatedSince the 10.10 upgrade my mouse clicks on my laptop have been behaving rather oddly. Sometimes it randomly does a middle click when i'm doing a left click, which is really annoying because it means that sometimes tabs close or my text gets random bits of text appearing in it. I've found that running this command "synclient tapbutton2=2 tapbutton3=0 rtcornerbutton=0 rbcornerbutton=0 clickfinger3=0" fixes it, but only temporarily, sometimes it only lasts like 10 minutes or so, other times it lasts till reboot. So, is there anyway to make these changes permanent?

I'm trying to make an environmental variable RPMS that will resolve to a website. I know I have to make the changes in .bash_profile, but all the things I try don't seem to want to work.
I've tried:
PATH=$RPMS:ftp://rha-server/pub/os/rhel5/Server/
or simply just making the variable itself
$RPMS=ftp://rha-server/pub/os/rhel5/Server/
The second one made a variable just fine, but when I attempted to run this command:
rpm -ihv $RPMS/caching-nameserver*
I am trying to strip the .wav file extension from a file name so that I can pass the result to lame encoder. I started to write a BASH script that looks like this:
Code:
for f in /home/user/wavfiles*; do FILE=basename $f .wav; lame $FILE; done
It doesn't work very well though. For the life of me I can't seem to discover how to use basename in a suitable way for a script like this.
