for example, this terminal command: ping www.google.com so my question is how can I create a launcher in my desktop can do this command, so there is no longer needs to open terminal every time and write this it.

Well you could create a new document on your Desktop, name it something.desktop like ping1.desktop

Then put this in, Name= & Icon= lines can be whatever you want (usually best to full path Icon=) or you can leave Icon= blank

[Desktop Entry]

Version=1.0

Type=Application

Terminal=true

Exec=ping www.google.com

Name=whatever you want

Icon= 

After creating right click on the launcher > Properties > Permissions > & check the Execute: box

(- you could also extend it's use to other pings if you use in unity's launcher via added quicklist entries in the .desktop

It took me a while to understand this because I'm a total Ubuntu beginner. Eventually, I figured it out. Rewritten in terms a dummy and a beginner like me might more easily understand:

1) Right click on desktop. From the pop-up menu select "New Document", then "Empty Document".

2) Name the document something.desktop, where "something" is replaced by the name you want.

3) Open the document with gedit (usually just by double clicking).

4) In gedit paste the following in, where "whatever you want" is the name of the launcher you choose, and where "path to icon", is the path to the icon you want, i.e. the directory location of the icon image:

[Desktop Entry]

Version=1.0

Type=Application

Terminal=true

Exec=ping www.google.com

Name= whatever you want

Icon= path to icon

5) After creating right click on the launcher > Properties > Permissions > & check the Execute: box

For example, to find the path to execute Spyder, type : "which spyder" in the terminal and the response was for me : /home/tech/anaconda3/bin/spyder

Then I wrote this in spyder.desktop :

[Desktop Entry]

Version=1.0

Type=Application

Terminal=false

Exec=/home/tech/anaconda3/bin/spyder

Name=spyder

Icon=/usr/share/spyder/images/spyder.png
