In ubuntu, add the icon shortcut for the program. For example, if I installed javaEE eclipse on my ubuntu, this software can be directly decompressed. At this time, there is no corresponding icon in the navigation bar, there is no icon in the Software Center in the upper left corner. You have to use commands to start the Software Center each time you start it. Now you can create an icon shortcut for it. Suppose that I decompress javaEE eclipse to open the terminal in/opt/eclipse, and sudo nano/usr/share/applications javaEE. enter [desktop Entry] Encoding = UTF-8 Name = JavaEE eclipse Comment = IDE for Rails, Python, PHP, JSP Exec =/opt/eclipse ------ Here is the startup command position of your program Icon =/opt/eclipse/icon. xpm ------- the icon you want to use. Generally, after the installation package is decompressed, there is an icon in it. You can also use another icon Terminal = false Type = Application Categories = GNOME; Application; Development; startupNotify = true and then save OK.
