Launchbar scripts12/7/2023 The -auto-kill option terminates the script if someone clicks "Cancel.".This informs the user something is happening and he should wait. The -pulsate option causes the progress dialog to display a moving indicator. The script cannot know in advance how much information the hwinfo command will produce, so it cannot set the progress bar to advance correctly to 100 percent.It sets the width and the height of the dialog window, and the title and prompt texts. The script creates a progress bar dialog window.tee sends the output into zenity and the TempFile. The script pipes the output from hwinfo into tee.If the value of Flag is "", nothing passes to hwinfo and a default, long scan is performed. If Flag contains "-short," the hwinfo command performs a short scan. The script calls the hwinfo command and passes it the value in the Flag variable.Now that the script knows which type of scan the user wants, we can perform the hardware information scan: If he presses "OK," we need to find out if he selected the "Short" or "Long" radio button: If the user presses "Cancel," we don't need to check the value in ListType, we can simply exit. column 'Scan Type' TRUE "Short" FALSE "Long"` ListType=`zenity -width=400 -height=275 -list -radiolist \ We're storing the result from this dialog window in a variable called ListType.This column holds two text labels: "Short" and "Long." The TRUE and FALSE indicators mean the "Short" option is selected by default when the dialog window appears. We set the title of the second column to be "Select," and we provide the content of the second column.We set the title of the first column to be "Select." The content of this column will be the radio buttons.We set a title and text prompt for the window.The -radiolist option causes the first column to be a column of radio buttons. The list dialog window supports columns.We specify a width and height for the window.The work-list function is called and piped into zenity.The echo lines that contain numbers, such as echo "25" , are also accepted by zenity and set the value of the progress bar.Change the text of these lines, so they pass informative messages to the user. " lines and displays them within the progress dialog window. Replace each of the sleep 1 commands with your real ones. This is where you put your commands and instructions to perform real work. The script defines a function called work-list.Work-list | zenity -progress -title "How-To Geek" -auto-close We can use that concept of piping values into zenity to include the progress dialog window in a script.Įnter this text in an editor and save it as "progress.sh." To give people an experience that's as frictionless as possible, you have to create and use GUI elements from your scripts. Most people are familiar with a graphical user interface (GUI). There are occasions when you do need something a little more intuitive and modern than the terminal window. Typically, such scripts don't need much (if any) user interaction. If the only person who'll ever use the script is its author, the interface probably isn't that important. Nor does it matter for scripts that perform background and batch type processing. Of course, sometimes the interface doesn't matter. The second complaint people have with Bash scripts is the user interface-it's a terminal window. You can often knock together a quick script and use it to perform a task much more quickly than developing a solution in a compiled language, such as C. However, this is like complaining that a tractor isn't as fast as a car they're meant for different things. Because the Bash shell interprets the commands in the script, they don't execute as quickly as compiled code. There are two main complaints people have with Bash scripts, and the first is speed.
