Many people use applications in groups or sets. This would require finding and double-clicking on several applications. Here is a way to make a double-clickable file that will open multiple applications at the same time.
In this example, I will be opening Explorer, Navigator and Mail. I am assuming these programs are all in your /Applications folder. If not you just have to modify the paths. Using your favorite text editor (vi, pico, BBEdit), create a new document and type in the following:
#!/bin/tcshIf would like to add more applications, go ahead and insert a few more "open" lines with the appropriate paths. Now, save the file as open.command and put it somewhere convenient like your desktop. If you want, you may change the part before the .command to anything else (like fun.command), but you must leave the .command part at the end. Next, go into a terminal and cd to the directory containing the open.command file. Type this at the prompt:
open /Applications/Internet Explorer.app&
open /Applications/Mail.app&
open /Applications/Navigator.app&
exit
% chmod +x open.commandThis makes your open.command file executable. Go to the desktop and double-click on the open.command file. Internet Explorer, Navigator and Mail should be launching.
