How to know the exact command to set as a startup program?

Question

I was looking for a way to set my weather indicator to launch right after the system startup.

I've found a nice and clear answer here. The answer says that the command to add to the startup programs is indicator-weather.

My question is, how may I know in advance that the command is "indicator-weather"? Why not "weather-indicator"? Where do I get that kind of information from?

Thanks!

Answer 1

Go to /usr/share/applications directory location (or your respective application location) and right-click to see properties. you will get the command field. This is the required command for you to use it for start-up command.

If it is not in application search the location of the executable file from whereis <nameofprogram>. It will give you many places (you need to search among them, generally from /usr/bin location). Then after finding the exact location of executable file use that path as command in startup application.

Answer 2

There is several ways to know the exact command to start an application.

• Using the command-line and dpkg:

  $ dpkg -S indicator-weather | grep "/bin/"
  /usr/bin/indicator-weather
  

• Or by looking at the package file list on package.ubuntu.com:

  http://packages.ubuntu.com/precise/all/indicator-weather/filelist

Both methods should help you to find the right command (e.g indicator-weather)
